Abstract:
The high incidence of aneurysms of different arterial systems in case of abdominal aortic aneurysm causes the need for the examination of all patients with aortic aneurysm in order to detect aneurysmal process in all main arteries. The use of the mentioned predictors of aneurism wall failure in daily clinical practice provides an opportunity to improve the results of surgical treatment. Active surgical approach in relation to aortic aneurysm and main arteries is indicated in the presence of aneurismal disease. The choice of treatment depends on the severity of the patient’s condition, clinical manifestations, localization of the aneurysm and its morphology, with the preference for endovascular approach.

Abstract:
Aortic disease is a collection of diseases of the aorta, which includes aortic aneurysms; acute aortic infections consisting of aortic dissection, intramular hematoma, penetration of atherosclerotic ulcers (PAU) and traumatic injury to the aorta; pseudoaneurysm; aortic rupture; Marfan syndrome; and congenital abnormalities such as coarctation of the aorta. One of the aortic diseases that cause the death rate to increase according to the 2010 Global Burden Disease is aortic aneurysm. Abdominal aortic aneurysm (AAA) is a focal dilatation of the aortic segment. The diagnosis of AAA is done by history taking, physical examination and supporting examination. Management at AAA aims to prevent aortic wall rupture. An alternative procedure without open surgery is endovascular aortic repair (EVAR) using prostheses. It is expected that through the EVAR method, mortality and morbidity due to AAA can be reduced. Keywords: abdominal aortic aneursym, EVAR, prostheses Penyakit aorta merupakan kumpulan penyakit pada aorta yang meliputi aneurisma aorta; sindrom aorta akut berupa diseksi aorta, hematoma intramular, penetrating atherosclerosis ulcer (PAU) dan cedera akibat trauma pada aorta; pseudoaneurysm; ruptur aorta; sindrom Marfan; serta penyakit kongenital seperti koarktasio aorta. Salah satu penyakit aorta yang menyebabkan angka kematian meningkat menurut Global Burden Disease 2010 adalah aneurisma aorta. Aneurisma aorta abdominalis (AAA) merupakan dilatasi fokal pada segmen aorta. Penegakan diagnosis AAA dilakukan dengan anamnesis, pemeriksaan fisik dan pemeriksaan penunjang. Penatalaksanaan pada AAA bertujuan untuk mencegah pecahnya dinding aorta.

Abstract:
The infrarenal abdominal aortic aneurysm is the most common among arterial aneurysms; it happens when there is an abnormal and irreversible enlargement of the blood vessel. This disease usually compromises other arterial segments and is linked to high mortality rates, mainly due to its rupture. Given its importance, we present a case study of an abdominal aortic aneurysm associated with a common iliac artery aneurysm. During a dissection practice in the Morphofunctional Laboratory at FACERES Medical School, we observed the presence of a mild stenosis in the abdominal aorta below the renal arteries, as well as the formation of an infrarenal abdominal aortic aneurysm. In addition, we noticed that the infrarenal abdominal aortic aneurysm was associated with a bilateral common iliac artery aneurysm. Morphological analyses carried out in the blood vessels showed a large quantity of atheromatous plaques, which are the probable cause of the pathology. The information herein may broaden the knowledge on the infrarenal abdominal aortic aneurysmal disease, thus reducing its complications and mortality rates.

Abstract:
Abdominal aortic aneurysms (AAA) are the most common arterial aneurysms. Endovascular or open surgical aneurysm repair is indicated in patients with large AAA ≥ 5.5 cm in diameter as this prevents aneurysm rupture. The presence even of small AAAs not in need of immediate repair is associated with a very high cardiovascular risk including myocardial infarction, stroke or cardiovascular death. This risk by far exceeds the risk of aneurysm rupture. These patients therefore should be considered as high-risk patients and receive optimal medical treatment and life-style modificiation of their cardiovascular risk factors to improve their prognosis. In addition, these patients should be followed-up for aneurysm growth and receive medical treatment to decrease aneurym progression and rupture rate. Treatment with statins has been shown to reduce cardiovascular mortality in these patients, and also slows the rate of AAA growth. Use of beta-blockers, ACE inhibitors and AT1-receptor antagonists does not affect AAA growth but may be indicated for comorbidities. Antibiotic therapy with roxithromycin has a small effect on AAA growth, but this effect must be critically weighed against the potential risk of wide-spread use of antibiotics.

Abstract:
Introduction. Abdominal aortic aneurysm diameter is one of the most important parameters in the diagnostic and therapeutic algorithm for aneurysm follow-up. Currently, two therapeutic modalities are used: open surgery and endovascular aortic repair. The aim of this study is to analyze the impact of the maximum transverse diameter of the abdominal aortic aneurysm on the incidence of general and specific complications. Material and Methods. The retrospective study included 75 patients with infrarenal abdominal aortic aneurysm who underwent endovascular aortic repair in the period from July 2008 to January 2020. The patients were divided into two groups: group A with an abdominal aortic aneurysm size ? 5.9 cm, and group B with an abdominal aortic aneurysm size ? 6.0 cm. Results. A total of 41.3% of patients presented with a maximum transverse aneurysm diameter of ? 5.9 cm, and 58.7% of patients had ? 6.0 cm. Of comorbid diseases, chronic obstructive pulmonary disease was more prevalent in patients with a large abdominal aortic aneurysm (group A 25.8%; group B 59.1%). None of the other comorbidities showed a statistically significant difference between the two groups of patients. Early complications were present in a total of 14.7% of patients, of which 12.9% of patients with a small and 15.9% with a large abdominal aortic aneurysm. Late complications occurred in a total of 18.7% of patients, in 9.7% of patients with a small and 25% of patients with a large abdominal aortic aneurysm. Conclusion. Patients with abdominal aortic aneurysms with a maximum transverse diameter of 6 cm and larger, present with a higher rate of late postoperative complications, increase in aneurysmal sac on control multislice computed tomography angiography, and have a worse prognosis compared to patients with smaller abdominal aortic aneurysms.

Abstract:
INTRODUCTION Inflammatory abdominal aortic aneurysm accounts for 5% to 10% of all cases of abdominal aortic aneurysm and differs from typical atherosclerotic abdominal aortic aneurysm in many important ways. Although both inflammatory and atherosclerotic abdominal aortic aneurysms most commonly affect the infrarenal portion of the abdominal aorta, patients with the inflammatory variant are younger and usually symptomatic, chiefly from back or abdominal pain. Unlike patients with atherosclerotic abdominal aortic aneurysm, most with the inflammatory variant have an elevated erythrocyte sedimentation rate or abnormalities of other serum inflammatory markers. Computed tomography and magnetic resonance imaging are both sensitive for demonstrating the cuff of soft tissue inflammation surrounding the aneurysm that is characteristic of inflammatory abdominal aortic aneurysm. Inflammatory abdominal aortic aneurysm can be primarily infected by degenaration of an infected artery (in less than 1% of cases), or can become secondary infected in the already existing aneurysm. Secondary infection of the pre-existing aneurysm has big influence on treatment choice, but is also rare. Clinically non-symptomatic infection, also known as bacterial collonisation, can be very frequent, regarding a greatly increased number of positive intraoperative findings (10-15%). Prolonged intravascular catheterization, vascular grafting, repeated punctures with large bore needles, and decreased immune defense mechanism make uraemic patients undergoing hemodialysis more likely to develop Staphylococcus aureus bacteraemia and its complications. CASE OUTLINE The case shows a gigantic inflammatory aneurysm of the abdominal aorta, localized infrarenally, which was solved successfully by resection of the aneurysm of the abdominal aorta, and interposition of Dacron tubular graft 22 mm. Bacterial examination of the aneurysmal sac was positive: methicillin-resistent Staphylococcus aureus was detected. CONCLUSION There were no postoperative complications, and the final outcome was fully satisfactory. Control CT scans after 3, 6 and 12 months were regular, with signs of regression fibrosis of the retroperitoneum.

Abstract:
INTRODUCTION Renal artery aneurysms is relatively uncommon with reported incidence ranges from 0.3% to 1%. However, considering all visceral artery aneurysms the percentage of renal artery aneurysms is relatively high between 15-25%. The distal forms of renal artery aneurysms sometimes require "ex vivo" reconstruction and kidney autotransplantation. CASE REPORT A 75-year-old male presented with the right abdominal and back pain. He suffered from a long history of arterial hypertension and chronic renal failure over the last few months (urea blood = 19.8 mmol/l; creatinine = 198 mmol/l). Duplex ultrasonography showed abdominal aortic aneurysm. Subsequent translumbarangiography revealed juxtarenal abdominal aortic aneurysm associated with distal right renal artery aneurysm. The operation was performed under combined thoracic epidural analgesia and general anesthesia using transperitoneal approach. After the laparotomy, the ascending colon was mobilized and reflected medially followed by Kocher maneuver. The result was visualization of the anterior aspect of the right kidney, the collecting system, ureter as well as the right renal vein and artery with large saccular aneurysm located distally. After mobilization of the renal vessels and careful dissection of the ureter, the kidney was explanted. The operation was continued by two surgical teams. The first team performed abdominal aortic aneurysm resection and reconstruction with bifurcated Dacron graft. The second team performed ex vivo reparation of renal artery aneurysm. All time during the explantation, the kidney was perfused by Collins' solution. The saccular right renal artery aneurysm 4 cm in diameter was located at the kidney hilus at the first bifurcation. Three branches originated from the aneurysm. The aneurysm was resected completely. The longest and widest of three branches arising from the aneurysmal sac was end-to-end anastomized with 6 mm PTFE graft. After this intervention, one of shorter arteries was implanted into the long artery, and another one into PTFE graft. After 30 minutes of explanation, autotransplantation of the kidney into the right iliac fossa was performed. The right renal vein was implanted into the inferior vein cava, and PTFE graft into the right limb of Dacron graft. Immediately following the completion of both anastomoses, large volume of urine was evident. Finally, ureteneocystostomy was performed with previous insertion of double "J" catheter. In the immediate postoperative period, renal function was restored to normal, while postoperative angiography revealed all patent grafts. DISCUSSION The most common causes of renal artery aneurysms are arteriosclerosis, as in our case, and fibro-muscular dysplasia. Very often, renal artery aneurysms are asymptomatic and discovered only during angiography in patients with aneurysmal and occlusive aortic disease. Other cases include: arterial hypertension, groin pain and acute or chronic renal failure. Due to relatively small number of evaluated cases, the risk of aneurysmal rupture is not known. According to some authors, the overall rupture rate of renal artery aneurysm is 5%, however, the rupture risk becomes higher in young pregnant woman. Several standard surgical procedures are available for the repair of renal artery aneurysms. These include saphenous vein angioplasty, bypass grafting, as well as ex vivo reconstruction with reimplantation or autotransplantation. Furthermore, interventional embolization therapy, as well as endovascular treatment with ePTFE covered stent, or autologous vein-coverage stent graft, have been also reported to be successful. CONCLUSION The major indications for surgical treatment of renal artery aneurysms are to eliminate the source of thromboembolism which leads to fixed renal hypertension and kidney failure, as well as prevention of aneurysmal rupture.

Abstract:
Relevance. Evidence exists that infrarenal aortic aneurisms and aortoiliac occlusive disease in women are different than in men in terms of anatomical features and more severe clinical course. Gender differences in histopathology of abdominal aorta are not fully studied.The objective was to study gender based differences in histopathology of abdominal aorta in patients with aortic aneurisms and aortoiliac occlusive disease.Methods and materials. The study included 96 biopsy specimens from 71 patients with aorto-iliac lesions (23 women and 48 men). A number of morphological characteristics and expression of matrix metalloproteinase 9 (MMP-9) were analyzed. The data obtained were processed statistically.Results. Adventitial infiltrate and medial sclerosis are more intense in the aneurysm than in occlusive-stenotic lesions, differences in the grade of fibrosis were proven only in men. Regardless of the patients’ gender, adventitial infiltration is denser in the aneurysmal body than in the neck; other changes in the anatomic parts of the aneurysm are similar. MMP-9 expression in the adventitia in the aneurysmal neck is higher in women, than in men. MMP-9 expression in the media and adventitia is higher in men with aneurysm, then with occlusive or stenotic lesion. Almost all indices of the aortic wall remodeling and MMP-9 expression correlate with each other in men with the aneurysm, in contrast to women.Conclusion. Gender based features in histopathology of abdominal aorta and the degree of their correlation may determine differences in the anatomy and course of abdominal aortic aneurysm and aortoiliac occlusive disease in women and men.

AbstractAortic aneurysms are usually asymptomatic until catastrophic rupture occurs. Ruptured abdominal aortic aneurysms classically present with acute back pain, shock, and a pulsatile abdominal mass. The natural history of some aortic aneurysms also includes a stage of contained rupture. This occurs when extravasation of blood from the ruptured aneurysm is contained by surrounding tissues. Here, the authors report the case of a chronic contained abdominal aortic aneurysm rupture that resulted in erosion of the spine.

Objective To analyze the characteristics of patients with abdominal aortic aneurysms referred to a tertiary center and to compare with individuals with abdominal aortic aneurysm found at necropsy. Methods We have retrospectively analyzed the medical records of 556 patients with abdominal aortic aneurysm and 102 cases abdominal aortic aneurysm found at necropsy. Results At univariated analysis, hypertension, tobacco use and maximum diameter were significant risk factors for symptomatic aneurysm, while diabetes tended to be a protective factor for rupture. By logistic regression analysis, the largest transverse diameter was the only one significantly associated with abdominal aortic aneurysm rupture ( p < .0001, odds ratio 1.7, 95% confidence interval 1.481–1.951). Intact abdominal aortic aneurysm found at necropsy showed similarities with outpatients in relation to abdominal aortic aneurysm diameter and risk factors. Conclusion Intact abdominal aortic aneurysm at necropsy and at outpatients setting showed similarities that confirmed that abdominal aortic aneurysm repair is less offered to women, and they died more frequently with intact abdominal aortic aneurysm from other causes.

Abstract:
ObjectiveUsing combined positron emission tomography and CT (PET-CT), we measured aortic inflammation and calcification in patients with abdominal aortic aneurysms (AAA), and compared them with matched controls with atherosclerosis.MethodsWe prospectively recruited 63 patients (mean age 76.1±6.8 years) with asymptomatic aneurysm disease (mean size 4.33±0.73 cm) and 19 age-and-sex-matched patients with confirmed atherosclerosis but no aneurysm. Inflammation and calcification were assessed using combined 18F-FDG PET-CT and quantified using tissue-to-background ratios (TBRs) and Agatston scores.ResultsIn patients with AAA, 18F-FDG uptake was higher within the aneurysm than in other regions of the aorta (mean TBRmax2.23±0.46 vs 2.12±0.46, p=0.02). Compared with atherosclerotic control subjects, both aneurysmal and non-aneurysmal aortae showed higher 18F-FDG accumulation (total aorta mean TBRmax2.16±0.51 vs 1.70±0.22, p=0.001; AAA mean TBRmax2.23±0.45 vs 1.68±0.21, p<0.0001). Aneurysms containing intraluminal thrombus demonstrated lower 18F-FDG uptake within their walls than those without (mean TBRmax2.14±0.43 vs 2.43±0.45, p=0.018), with thrombus itself showing low tracer uptake (mean TBRmax thrombus 1.30±0.48 vs aneurysm wall 2.23±0.46, p<0.0001). Calcification in the aneurysmal segment was higher than both non-aneurysmal segments in patients with aneurysm (Agatston 4918 (2901–8008) vs 1017 (139–2226), p<0.0001) and equivalent regions in control patients (442 (304-920) vs 166 (80-374) Agatston units per cm, p=0.0042).ConclusionsThe entire aorta is more inflamed in patients with aneurysm than in those with atherosclerosis, perhaps suggesting a generalised inflammatory aortopathy in patients with aneurysm. Calcification was prominent within the aneurysmal sac, with the remainder of the aorta being relatively spared. The presence of intraluminal thrombus, itself metabolically relatively inert, was associated with lower levels of inflammation in the adjacent aneurysmal wall.

Abstract:
Abdominal aortic aneurysms are a common health problem and currently the need for surgical intervention is determined based on maximum diameter and growth rate criteria. Since these universal variables often fail to predict accurately every abdominal aortic aneurysms evolution, there is a considerable effort in the literature for other markers to be identified towards individualized rupture risk estimations and growth rate predictions. To this effort, biomechanical tools have been extensively used since abdominal aortic aneurysm rupture is in fact a material failure of the diseased arterial wall to compensate the stress acting on it. The peak wall stress, the role of the unique geometry of every individual abdominal aortic aneurysm as well as the mechanical properties and the local strength of the degenerated aneurysmal wall, all confer to rupture risk. In this review article, the assessment of these variables through mechanical testing, advanced imaging and computational modeling is reviewed and the clinical perspective is discussed.

The risk of cardiovascular disease begins to increase from the early stages of chronic kidney disease (CKD). Abdominal aortic aneurysms are the most common arterial aneurysms of peripheral arterial diseases. The frequency of abdominal aortic aneurysm varies according to the population studied. This study aimed to determine the prevalence of abdominal aortic aneurysm in patients with stage 3-4 CKD and investigate CKD is a risk factor for abdominal aortic aneurysm formation. Methods. Patients aged 55 years and older who were followed up in the internal medicine outpatient clinics were enrolled. Two hundred CKD patients with glomerular filtration rates between 15-59 mL/min per 1.73 m2 were included in the study group, and 110 patients with glomerular filtration rates of 60 mL/min per 1.73 m2 or above were assigned to the control group. An ultrasonography device with a 3.5 MHz probe was used for screening. Abdominal aortic diameters of 3 cm and above were accepted as abdominal aortic aneurysms. Results. Eighteen patients in the study group (9%) and four in the control group (3.6%) had an abdominal aortic aneurysm. The prevalence of abdominal aortic aneurysms was higher in the CKD group. However, the difference was not statistically significant (p=0.078). Moreover, the median aortic diameter was 21.8 mm (14-44 mm) in the study group, compared to 21.0 mm (14-46 mm) in the control group. The prevalence of the abdominal aortic aneurysm was 14.9% in stage 4 CKD patients and 6% in stage 3 CKD patients (p=0.038). Conclusion. An abdominal aortic aneurysm is more common in patients with CKD although it does not reach statistical significance. The median aortic diameter was significantly wider in CKD patients compared to the control group . The prevalence of abdominal aortic aneurysm increased with an increase in the CKD stage .

The presence of associated cerebral aneurysm and abdominal aortic aneurysm is an extremely rare degenerative vascular pathology. The article describes a two-stage treatment of a patient with aneurysms that occur in different types of blood vessels characterized by different hemodynamic conditions. A 56-year-old man suffering from hypertension complained of abdominal pain, headache, and dizziness. The exam-ination revealed multiple aneurysms: in the abdominal and iliac arteries, as well as an ophthalmic artery aneurysm of the internal carotid ar-tery. Surgical interventions were carried out in stages: osteoplastic pterional craniotomy with aneurysm clipping of the right internal carotid artery with vascular ultrasound and endoprosthesis of abdominal aorta and iliac arteries with a stent graft. The patient was discharged in a satisfactory condition. Regression of clinical disease manifestations was found. It was shown that the key point was to create a multidisci-plinary team and determine the stages of surgical treatment when managing such patients.KEYWORDS: abdominal aortic aneurysm, iliac artery aneurysm, cerebral aneurysm, hypertension, degenerative pathology, treatment stages.FOR CITATION: Gilemkhanov A.R., Plechev V.V., Ishmetov V.Sh. et al.

Abstract:
Background Abdominal aortic aneurysms can be either treated by an open abdominal aortic aneurysm repair or an endovascular repair. Comparing clinical predictors of outcomes and those which influence survival rates in the long term is important in determining the choice of treatment offered and the decision-making process with patients. Aims To determine the influence of pre-existing clinical predictors and perioperative determinants on late survival of elective open abdominal aortic aneurysm repair and endovascular repair at a tertiary hospital. Methods Consecutive patients undergoing elective abdominal aortic aneurysm repair from 1990 to 2013 were included. Data were collected from a prospectively acquired database and death data were gathered from the Queensland state death registry. Pre-existing risks and perioperative factors were assessed independently. Kaplan–Meier and Cox regression modeling were performed. Results During the study period, 1340 abdominal aortic aneurysms were repaired electively, of which 982 were open abdominal aortic aneurysm repair. The average age was 72.4 years old and 81.7% were males. The cumulative percentage survival rates for open abdominal aortic aneurysms repair at 5, 10, 15 and 20 years were 79, 49, 31 and 22, respectively. The corresponding 5-, 10- and 15-year survival rates for endovascular repair were not significantly different at 75, 49 and 33%, respectively (P = 0.75). Predictors of reduced survival were advanced age, American Society of Anaesthesiology scores, chronic obstructive pulmonary disease, renal impairment, bifurcated grafts, peripheral vascular disease and congestive heart failure. Conclusions Open repair offers a good long-term treatment option for patients with an abdominal aortic aneurysm and in our experience there is no significant difference in late survival between open abdominal aortic aneurysms repair and endovascular repair. Consideration of the factors identified in this study that predict reduced long-term survival for open abdominal aortic aneurysms repair and endovascular repair should be considered when deciding repair of abdominal aortic aneurysm.

Abstract:
Background and Aims: According to the heterogeneous results of previous studies, the prevalence of abdominal aortic aneurysm seems high among men with coronary artery disease. The associating risk factors for abdominal aortic aneurysm in this population require clarification. Our objective was to assess the prevalence of non-diagnosed abdominal aortic aneurysms in men with angiographically verified coronary artery disease and to document the associated co-morbidities and risk factors. Material and Methods: Altogether, 407 men with coronary artery disease were screened after invasive coronary angiography in two series at independent centers. Risk factor data were recorded and analyzed. Results and Conclusion: The mean age of the study cohort was 70.0 years (standard deviation: 11.0). The prevalence of previously undiagnosed abdominal aortic aneurysms in the whole screened population of 407 men was 6.1% (n = 25/407). In a multivariate analysis of the whole study population, the only significant risk factors for abdominal aortic aneurysm were age (odds ratio: 1.04, 95% confidence interval: 1.00–1.09) and history of smoking (odds ratio: 3.13, 95% confidence interval: 1.26–7.80). Non-smokers with abdominal aortic aneurysm were significantly older than smokers (mean age: 80.7 (standard deviation: 8.0) vs 68.0 (standard deviation: 11.1), p = 0.003), and age was a significant risk factor only among non-smokers (p = 0.011; p = 0.018 for interaction). Among smokers, the prevalence of abdominal aortic aneurysm was 8.8%, and 72% (n = 18/25) of all diagnosed abdominal aortic aneurysm patients were smokers. Prevalence of undiagnosed abdominal aortic aneurysms among patients with coronary artery disease is high, and history of smoking is the most significant risk factor for abdominal aortic aneurysm. Effectiveness of selective screening of abdominal aortic aneurysm in male patients with coronary artery disease warrants further studies.

Abstract:
Objectives: Abdominal aortic aneurysms are associated with a sharply increased cardiovascular risk. Cardiovascular risk management is therefore recommended in prevailing guidelines for abdominal aneurysm patients. It has been hypothesized that associated risk relates to loss of aortic compliance. If this hypothesis is correct, observations for abdominal aneurysms would also apply to thoracic aortic aneurysms. The objective of this study is to test whether thoracic aneurysms are also associated with an increased cardiovascular risk burden. Methods: Patients who underwent aortic valve or root surgery were included in the study (n = 239). Cardiovascular risk factors were studied and atherosclerosis was scored based on the preoperative coronary angiographies. Multivariate analyses were performed, controlling for cardiovascular risk factors and aortic valve morphology. Comparisons were made with the age- and gender-matched general population and non-aneurysm patients as control groups. A thoracic aortic aneurysm was defined as an aortic aneurysm of ≥45 mm. Results: Thoracic aortic aneurysm was not associated with an increased coronary atherosclerotic burden (p = 0.548). Comparison with the general population revealed a significantly higher prevalence of hypertension (61.4% vs. 32.2%, p < 0.001) and a lower prevalence of diabetes (1.4% vs. 13.1%, p = 0.001) in the thoracic aneurysm group. Conclusions: The extreme cardiovascular risk associated with abdominal aortic aneurysms is location-specific and not explained by loss of aortic compliance. Thoracic aortic aneurysm, in contrast to abdominal, is not part of the atherosclerotic disease spectrum and, therefore, cardiovascular risk management does not need to be implemented in treatment guidelines of isolated thoracic aneurysms. Hypertension should be treated.

This is the second article in a series of articles regarding screening programmes. In this article, an overview of the abdominal aorta is provided. The article also considers the abdominal aortic aneurysm screening programme. Aortic abdominal aneurysm is described. The majority of abdominal aortic aneurysms are asymptomatic; however, if there are any symptoms, these are explained. All four UK countries offer men aged 65 years and over a screening opportunity using an ultrasound scan, the fundamental aspects of abdominal aortic aneurysm screening programmes is offered. It is emphasised that screening is not mandatory in the UK; the man has a right to decline the invitation to attend any screening programme.

Abstract:
Background Studies reporting the influence of preoperative abdominal aortic aneurysm diameter on late survival following abdominal aortic aneurysm repair have not been consistent. Aim: To report the influence of abdominal aortic aneurysm diameter on overall long-term survival following abdominal aortic aneurysm repair. Methods Embase, Medline and the Cochrane electronic databases were searched to identify articles reporting the influence of abdominal aortic aneurysm diameter on late survival following open aneurysm repair and endovascular aneurysm repair published up to April 2015. Data were extracted from multivariate analysis; estimated risks were expressed as hazard ratio. Results A total of 2167 titles/abstracts were retrieved, of which 76 studies were fully assessed; 19 studies reporting on 22,104 patients were included. Preoperative larger abdominal aortic aneurysm size was associated with a worse survival compared to smaller aneurysms with a pooled hazard ratio of 1.14 (95% CI: 1.09–1.18), per 1 cm increase in abdominal aortic aneurysm diameter. Subgroup analysis of the different types of repair was performed and the hazard ratio (95% CI), for open aneurysm repair and endovascular aneurysm repair were 1.08 (1.03–1.12) and 1.20 (1.15–1.25), respectively, per 1 cm increase. There was a significant difference between the groups p < 0.02. Conclusions This meta-analysis suggests that preoperative large abdominal aortic aneurysm independently influences overall late survival following abdominal aortic aneurysm repair, and this association was greater in abdominal aortic aneurysm repaired with endovascular aneurysm repair.

Abstract:
Background Abdominal aortic aneurysm has become increasingly important owing to demographic changes. Some other diseases, for example, cholecystolithiasis, chronic obstructive pulmonary disease, and hernias, seem to co-occur with abdominal aortic aneurysm. The aim of this retrospective analysis was to identify new comorbidities associated with abdominal aortic aneurysm. Methods We compared 100 patients with abdominal aortic aneurysms and 100 control patients. Their preoperative computed tomographic scans were examined by two investigators independently, for the presence of hernias, diverticulosis, and cholecystolithiasis. Medical records were also reviewed. Statistical analysis was performed using univariate analysis and multiple logistic regression analysis. Results The aneurysm group had a higher frequency of diverticulosis (p = 0.008). There was no significant difference in the occurrence of hernia (p = 0.073) or cholecystolithiasis (p = 1.00). Aneurysm patients had a significantly higher American Society of Anesthesiology score (2.84 vs. 2.63; p = 0.015) and were more likely to have coronary artery disease (p < 0.001), congestive heart failure (p < 0.001), or chronic obstructive pulmonary disease (p < 0.001). Aneurysm patients were more likely to be former (p = 0.034) or current (p = 0.006) smokers and had a significantly higher number of pack years (p < 0.001). Aneurysm patients also had a significantly poorer lung function. In multivariate analysis, the following factors were associated with aneurysms: chronic obstructive pulmonary disease (odds ratio, OR = 12.24; p = 0.002), current smoking (OR = 4.14; p = 0.002), and coronary artery disease (OR = 2.60; p = 0.020). Conclusions Our comprehensive analysis identified several comorbidities associated with abdominal aortic aneurysms. These results could help to recognize aneurysms earlier by targeting individuals with these comorbidities for screening.

Abstract:
In rare cases, the celiac artery and the superior mesenteric artery arise from a common origin known as a common celiacomesenteric trunk. Celiac trunk stenosis or occlusion has been reported to accompany this anatomical aberrancy. Even rarer, are aneurysms associated with this common celiacomesenteric trunk. In general, visceral artery aneurysms are uncommon. We hereby present a 39-year-old female patient with a 1-month history of mild diffuse abdominal pain, with an incidental finding of superior mesenteric artery aneurysm on abdominal ultrasound. Subsequent contrast-enhanced computed tomography revealed severe narrowing of the celiac trunk and saccular aneurysmal dilatation of the superior mesenteric artery. Coil embolization of the aneurysm was performed, while maintaining persistent flow in the superior mesenteric artery and celiacomesenteric trunk. Visceral artery aneurysms are increasingly being identified incidentally with improvement in imaging techniques. The question lies whether to treat these aneurysms or observe. No universal guidelines exist regarding that matter, but the decision to intervene is made based on aneurysm location, size, and patient characteristics.

Abstract:
This investigation evaluated the results of single-stage thoracic endovascular aneurysm repair (TEVAR) and endovascular aneurysm repair (EVAR) for multilevel aortic disease in a series of nine patients. The lesions repaired included thoracic and abdominal aortic aneurysms ( n = 7) and subacute type B dissections with abdominal aortic aneurysms ( n = 2). All procedures were successfully performed, and none of the patients experienced postoperative stroke or spinal cord ischemia. The median follow-up period for these patients was 18.9 months (range 1.7–31.4 months) and none of the patients exhibited any signs of type I endoleaks or aneurysmal diameter enlargements more than 5 mm. In conclusion, single-stage TEVAR and EVAR procedures for multilevel aortic disease were found to be safe and feasible modalities for high-risk patients.

Abstract:
AbstractTo contribute to the understanding of flow phenomena in abdominal aortic aneurysms, numerical computations of pulsatile flows through aneurysm models and a stability analysis of these flows were carried out. The volume flow rate waveforms into the aneurysms were based on measurements of these waveforms, under rest and exercise conditions, of patients suffering abdominal aortic aneurysms. The Reynolds number and Womersley number, the dimensionless quantities that characterize the flow, were varied within the physiologically relevant range, and the two geometric quantities that characterize the model aneurysm were varied to assess the influence of the length and maximal diameter of an aneurysm on the details of the flow. The computed flow phenomena and the induced wall shear stress distributions agree well with what was found in PIV measurements by Salsac et al. (J. Fluid Mech., vol. 560, 2006, pp. 19–51). The results suggest that long aneurysms are less pathological than short ones, and that patients with an abdominal aortic aneurysm are better to avoid physical exercise. The pulsatile flows were found to be unstable to three-dimensional disturbances if the aneurysm was sufficiently localized or had a sufficiently large maximal diameter, even for flow conditions during rest. The abdominal aortic aneurysm can be viewed as acting like a ‘wavemaker’ that induces disturbed flow conditions in healthy segments of the arterial system far downstream of the aneurysm; this may be related to the fact that one-fifth of the larger abdominal aortic aneurysms are found to extend into the common iliac arteries. Finally, we report a remarkable sensitivity of the wall shear stress distribution and the growth rate of three-dimensional disturbances to small details of the aneurysm geometry near the proximal end. These findings suggest that a sensitivity analysis is appropriate when a patient-specific computational study is carried out to obtain a quantitative description of the wall shear stress distribution.

The mycotic tuberculous aneurysm of the Abdominal Aorta is an extremely rare disease. An aortic mycotic aneurysm is a life-threatening condition caused by tuberculous infection. Tuberculous aneurysms of the aorta usually present as rapidly growing or ruptured pseudoaneurysms. Most of these aneurysms are of the pseudoaneurysm type. We presented a case of a 61-year-old man who was diagnosed with a tubercular abdominal aortic mycotic aneurysm associated with the posterior invasion of the vertebral body leading to discitis. The patient underwent a mycotic aneurysm repair with grafting. Even with a combination of surgical and medical treatment, a favorable outcome could not be achieved.

Abstract:
Inflammation plays a part in the development of abdominal aortic aneurysm (AAA), and the gut microbiota affects host inflammation by bacterial translocation. The relationship between abdominal aortic aneurysm and the gut microbiota remains unknown. This study aimed to detect bacterial translocation in the aneurysmal wall and blood of patients with abdominal aortic aneurysm, and to investigate the effect of the gut microbiota on abdominal aortic aneurysm. We investigated 30 patients with abdominal aortic aneurysm from 2017 to 2019. We analysed the aneurysmal wall and blood using highly sensitive reverse transcription-quantitative polymerase chain reaction, and the gut microbiota was investigated using next-generation sequencing. In the 30 patients, bacteria were detected by reverse transcription- quantitative polymerase chain reaction in 19 blood samples (detection rate, 63%) and in 11 aneurysmal wall samples (detection rate, 37%). In the gut microbiota analysis, the Firmicutes/Bacteroidetes ratio was increased. The neutrophil-lymphocyte ratio was higher (2.94 ± 1.77 vs 1.96 ± 0.61, P < 0.05) and the lymphocyte-monocyte ratio was lower (4.02 ± 1.25 vs 5.86 ± 1.38, P < 0.01) in the bacterial carrier group than in the bacterial non-carrier group in blood samples. The volume of intraluminal thrombus was significantly higher in the bacterial carrier group than in the bacterial non-carrier group in aneurysmal wall samples (64.0% vs 34.7%, P < 0.05). We confirmed gut dysbiosis and bacterial translocation to the blood and aneurysmal wall in patients with abdominal aortic aneurysm. There appears to be a relationship between the gut microbiota and abdominal aortic aneurysm.

ABSTRACT Objective: to determine the blood flow pattern changes after endovascular treatment of saccular abdominal aortic aneurysm with triple stent. Methods: we conducted a hemodynamic study of seven Landrace and Large White pigs with saccular aneurysms of the infrarenal abdominal aorta artificially produced according to the technique described. The animals were subjected to triple stenting for endovascular aneurysm. We evaluated the pattern of blood flow by duplex scan before and after stent implantation. We used the non-paired Mann-Whitney test for statistical analysis. Results: there was a significant decrease in the average systolic velocity, from 127.4cm/s in the pre-stent period to 69.81cm/s in the post-stent phase. There was also change in the flow pattern from turbulent in the aneurysmal sac to laminate intra-stent. Conclusion: there were changes in the blood flow pattern of saccular abdominal aortic aneurysm after endovascular treatment with triple stent.

Abstract:
Background: Besides biological factors, abdominal aortic aneurysm rupture is also caused by mechanical parameters, which are constantly affecting the wall’s tissue due to their abnormal values. The ability to evaluate these parameters could vastly improve the clinical treatment of patients with abdominal aortic aneurysms. The objective of this study was to develop and demonstrate a methodology to analyze the fluid dynamics that cause the wall stress distribution in abdominal aortic aneurysms, using accurate 3D geometry and a realistic, nonlinear, elastic biomechanical model using a computer-aided software. Methods: The geometry of the abdominal aortic aneurysm; was constructed on a 3D scale using computer-aided software SolidWorks (Dassault Systems SolidWorksCorp., Waltham MA). Due to the complex nature of the abdominal aortic aneurysm geometry, the physiological forces and constraints acting on the abdominal aortic aneurysm wall were measured by using a simulation setup using boundary conditions and initial conditions for different studies such as finite element analysis or computational fluid dynamics. Results: The flow pattern showed an increase velocity at the angular neck, followed by a stagnated flow inside the aneurysm sack. Furthermore, the wall shear stress analysis showed to focalized points of higher stress, the top and bottom of the aneurysm sack, where the flow collides against the wall. An increase of the viscosity showed no significant velocity changed but results in a slight increase in overall pressure and wall shear stress. Conclusions: Conducting computational fluid dynamics modeling of the abdominal aortic aneurysm using computer-aided software SolidWorks (Dassault Systems SolidWorksCorp., Waltham MA) proves to be an insightful approach for the clinical setting. The careful consideration of the biomechanics of the abdominal aortic aneurysm may lead to an improved, case-specific prediction of the abdominal aortic aneurysm rupture potential, which could significantly improve the clinical management of these patients.

Abstract:
In this paper, we have constructed a three-dimensional abdominal aorta aneurysm model based on the CT-scan/angiography images. The inlet velocity is pulsatile and the simulation was done by means of finite volume analysis. The velocity and pressure contours were obtained for four different aneurysm sizes in three sections. The results indicate that the velocity decreases in aneurysm wall but pressure increases in that area. Furthermore, the increase of the aneurysm diameter increases the rupture risk due to high pressure in the wall. The shear stress is high in the start point and end of the aneurysm's curvature. Our study indicates that the aneurysm diameter is directly related to the pressure. High blood pressure could be a risk factor in artery rapture. Our model can serve as a useful tool for the study of the aortic aneurysms.

Aim. Although osteopontin (OPN) and osteoprotegerin (OPG) have been associated with abdominal aortic aneurysms (AAAs), no association of these two biomarkers with AAA surgical or endovascular treatment has been reported. Material and Methods. Seventy-four AAA patients were prospectively selected for open or endovascular repair. All aneurysms were classified (Types A–E) according to aneurysmal extent in CT imaging (EUROSTAR criteria). All patients had preoperative serum OPN and OPG values measurements and 1 week after the procedure. Preoperative and postoperative values were compared with a control group of twenty patients (inguinal hernia repair). Results. Preoperative OPN values in patients with any type of aneurysm were higher than in the control group, while OPG values showed no difference. Postoperative OPN values in AAA patients were higher than in the control group. OPN values increased after open surgery and after EVAR. OPG values increased after open surgery but not after EVAR. There was no difference in OPN/OPG values between EVAR and open surgery postoperatively. Conclusions. OPN values are associated with aneurysm presence but not with aneurysm extent. OPG values are not associated either with aneurysm presence or with aneurysm extent. OPN values increase after AAA repair, independently of the type of repair.

Abstract:
Introduction. An abdominal aortic aneurysm is a permanent focal dilation of the blood vessel wall to about 1.5 times larger than the normal diameter. Clinically, it may be divided into symptomatic and asymptomatic. It is still discussed whether patients with symptomatic non-ruptured abdominal aortic aneurysm benefit more from emergency or delayed surgical treatment. The aim of the study was to evaluate the results of the symptomatic non-ruptured aneurysms in regard to the diameter of ruptured and non-ruptured symptomatic aneurysms and the impact of the time elapsed from admission to surgery on its outcome. Material and Methods. The retrospective study included all 133 patients who underwent surgery due to symptomatic non-ruptured or ruptured abdominal aortic aneurysm at the Clinic of Vascular and Endovascular Surgery during the previous 3 years. Results. Out of a total of 133 patients, 75.19% underwent surgery in the first 24 hours after admission, while the rest 24.81% of patients were operated later. Intraoperative complications were recorded only in patients with ruptured aneurysms, 4% had cardiac arrest and 1.5% of patients had fatal outcome. The in-hospital mortality was 16.67% in patients with non-ruptured aneurysm of the abdominal aorta operated in the first 24 hours, and 9.91% in patients who were operated after 24 hours after admission. Conclusion. Early elective surgery is a method of choice in the treatment of symptomatic non-ruptured aneurysm of the abdominal aorta. However, surgical treatment in the first 24 hours is associated with a higher mortality rate than surgery after 24 hours after admission. Also, there is no statistically significant difference in the diameter of ruptured and non-ruptured symptomatic aneurysms, but the average size of the aneurysm diameter is higher in ruptured than in non-ruptured aneurysms, which confirms the fact that the increase in diameter increases the risk of aneurysm rupture.

Abstract:
OBJECTIVES: To assess the accuracy of screening for abdominal aortic aneurysms (AAAs) by ultrasound (US). SETTING: An aneurysm screening programme in Huntingdon. METHODS: False negative tests were identified by tracing all patients with a ruptured aneurysm who were screened and then finding the number classified as normal on US. False positive tests were identified by calculating the number of aneurysmal aortas on US that were classified as normal on CT. Measurement variability of the infrarenal aortic diameter between US and CT was estimated. RESULTS: 14 out of 93 patients with a ruptured AAA since 1991 had been screened. No ruptured aneurysm had been classified as normal on US. All 64 patients with an AAA larger than 4.5 cm on US had their aneurysm confirmed on CT. The mean difference between CT and US measurements was 4 mm. The limit of variability between CT and US was 12 mm. CONCLUSION: No false negative scans were found using a cut off point of 3 cm as abnormal. No false positives were found if subjects with an AAA exceeding 4.5 cm were referred for further procedures. A serial US screening policy has excellent screening performance, justifying its use as a screening tool.

Splenic artery aneurysm (SAA) is a rare condition in abdominal surgery and the third most abdominal aneurysm after aortic and iliac artery aneurysms. Open surgery during the giant SAA is still the gold standard of treatment. Here we present the case of the giant SAA in a 68-year-old man. He had a pancreatic mass and iron deficiency anemia. The diagnosis was confirmed by ultrasound and CT angiography and showed a pancreatic mass and expansion of the splenic artery more than 3.5 cm. The size of the aneurysm and the clinical picture of the patient were indications for open surgery. The patient was treated by resection of the spleen and distal pancreatectomy with the aneurysmal part of the splenic artery. As far as we know, open surgery is still the best treatment choice, despite some advances in endovascular methods.

Abstract:
Today, abdominal aortic aneurysm surgery is a fairly well-studied area of medicine. Nevertheless, some questions remain rather debatable. No clear criteria for giant aneurysms have been developed so far. The available foreign and domestic literature reports about 40 cases of surgical treatment of giant abdominal aortic aneurysms, 16 of which are cases of aneurysm rupture. Open surgery remains the method of choice in the treatment of giant aneurysms due to the pronounced technical difficulties of endovascular intervention. The authors present a case of successful surgical treatment of a giant aneurysm rupture in an elderly patient. The peculiarity of this patient's condition is the occurrence of aneurysm rupture after hospital admission. The patient refused surgical treatment for two years after aneurysm detection. On examination after admission, multispiral computed tomography revealed an aneurysm size of 101 mm. On the eve of surgery, pain syndrome in the left abdomen and tachycardia appeared. Aneurysm rupture was suspected and the patient was urgently admitted to the operating room. The surgery was performed under the conditions of machine reinfusion of autoblood. The patient underwent abdominal aortic aneurysm resection with linear prosthesis and retroperitoneal hematoma removal. The postoperative period had no peculiarities. On the 10th day after the operation the patient was discharged in satisfactory condition to the outpatient treatment. This clinical case demonstrates the possibility of successful surgical treatment of giant aneurysm rupture in elderly patients.

Aneurysms are characterized by structural deterioration of the vascular wall leading to progressive dilatation and, potentially, rupture of the aorta. While aortic aneurysms often remain clinically silent, the morbidity and mortality associated with aneurysm expansion and rupture are considerable. Over 13,000 deaths annually in the United States are attributable to aortic aneurysm rupture with less than 1 in 3 persons with aortic aneurysm rupture surviving to surgical intervention. Environmental and epidemiologic risk factors including smoking, male gender, hypertension, older age, dyslipidemia, atherosclerosis, and family history are highly associated with abdominal aortic aneurysms, while heritable genetic mutations are commonly associated with aneurysms of the thoracic aorta. Similar to other forms of cardiovascular disease, family history, genetic variation, and heritable mutations modify the risk of aortic aneurysm formation and provide mechanistic insight into the pathogenesis of human aortic aneurysms. This review will examine the relationship between heritable genetic and epigenetic influences on thoracic and abdominal aortic aneurysm formation and rupture.

AbstractMycotic aneurysms, often saccular, accounting for approximately 2.5% of all abdominal aortic aneurysms, possess increased risk of rupture, uncontrolled sepsis, and protracted hospital stay and are associated with high morbidity and mortality. The authors report the case of a 49-year-old female with no known comorbidities who presented with free rupture of an infrarenal dissecting mycotic aneurysm and underwent emergent open repair successfully. The etiological agent, Brucella melitensis, a Gram-negative zoonotic coccobacillus, is rarely reported to cause mycotic aneurysm.

Abstract:
Patient with Syphilitic Thoracic and Abdominal Aortic AneurysmsWe are presenting a rare case of patient with two syphilitic aneurysms localized in thoracic and abdominal aorta. Routine lung computer tomography (CT) for the patient with complains about irritating and unclear ethiology cough revealed 10 cm diameter aneurysm of descending thoracic aorta (TAA) and additionally 4.8 cm aneurysm of abdominal aorta (AAA) just below the aortic hiatus. As there was no evidence of previous trauma, Marfan syndrome or connective tissue disease patient was screened for syphilis. Diagnosis of tertiary syphilis was confirmed and specific treatment started. As complains of irritating cough intensified - patients TAA was successfully treated endovascularly with thoracic stent graft (Valiant®Captivia, Medtronic Ltd.) on emergency basis. On control CT angiography 3 month after treatment there was no evidence of graft migration, endoleaks and aneurysmal sac was thrombosed. AAA has not increased in size, and open repair is planned.

Abstract:
The pathogenesis of abdominal aortic aneurysm involves vascular inflammation and elastin degradation. Astragalusradix contains cycloastragenol, which is known to be anti-inflammatory and to protect against elastin degradation. We hypothesized that cycloastragenol supplementation inhibits abdominal aortic aneurysm progression. Abdominal aortic aneurysm was induced in male rats by intraluminal elastase infusion in the infrarenal aorta and treated daily with cycloastragenol (125 mg/kg/day). Aortic expansion was followed weekly by ultrasound for 28 days. Changes in aneurysmal wall composition were analyzed by mRNA levels, histology, zymography and explorative proteomic analyses. At day 28, mean aneurysm diameter was 37% lower in the cycloastragenol group (p < 0.0001). In aneurysm cross sections, elastin content was insignificantly higher in the cycloastragenol group (10.5% ± 5.9% vs. 19.9% ± 16.8%, p = 0.20), with more preserved elastin lamellae structures (p = 0.0003) and without microcalcifications. Aneurysmal matrix metalloprotease-2 activity was reduced by the treatment (p = 0.022). Messenger RNA levels of inflammatory- and anti-oxidative markers did not differ between groups. Explorative proteomic analysis showed no difference in protein levels when adjusting for multiple testing. Among proteins displaying nominal regulation were fibulin-5 (p = 0.02), aquaporin-1 (p = 0.02) and prostacyclin synthase (p = 0.007). Cycloastragenol inhibits experimental abdominal aortic aneurysm progression. The suggested underlying mechanisms involve decreased matrix metalloprotease-2 activity and preservation of elastin and reduced calcification, thus, cycloastragenol could be considered for trial in abdominal aortic aneurysm patients.

Abstract:
Retroperitoneal fibrosis is a rare fibrosing reactive process that may be confused with mesenteric fibromatosis. Abdominal aorta aneurysm is rare too and mostly develops secondary to Behcet’s disease, trauma, and infection or connective tissue diseases. Incidence of aneurysms occurring as a result of atherosclerotic changes increases in postmenopausal period. Diagnosis can be established with arteriography, tomography, or magnetic resonance imaging associated with clinical findings. Tumors and cysts should be considered in differential diagnosis. Abdominal ultrasound and contrast-enhanced computerized tomography revealed an infrarenal abdominal aorta aneurysm in a 41-year-old woman, but, on surgery, retroperitoneal fibrosis surrounding the aorta was detected. We present this interesting case because retroperitoneal fibrosis encircling the abdominal aorta can mimic abdominal aorta aneurysm radiologically.

Abstract:
Purpose: To describe the successful endovascular repair and regression of an extensive descending thoracoabdominal aortic dissection associated with thoracic and abdominal aortic aneurysms. Case Report: An 83-year-old man presented with acute chest pain and shortness of breath. A descending thoracoabdominal aortic dissection that extended from near the left subclavian artery (LSA) to the right common iliac artery was found on computed tomography. Separate aneurysms in the thoracic and abdominal aorta were also identified. Staged endovascular procedures were undertaken to (1) close the single entry site and exclude the aneurysm in the thoracic aorta with an AneuRx thoracic stent-graft, (2) exclude the abdominal aneurysm and distal re-entry site with a bifurcated AneuRx endograft, and (3) treat a newly dilated thoracic segment between the LSA and first thoracic stent-graft. At 1 year, the false lumen had completely disappeared, the thoracic aneurysm had collapsed onto the endograft, and the abdominal aneurysm had shrunk by 30%. Conclusions: The potential to treat extensive aortic dissections with the hope that they might regress is promising, but repair of highly complex lesions involving one or more aneurysms in addition to the dissection requires meticulous imaging studies both preoperatively and intraprocedurally.

Abstract:
Background. Most available large animal extracranial aneurysm models feature healthy non-degenerated aneurysm pouches with stable long-term follow-ups and extensive healing reactions after endovascular treatment. This review focuses on a small subgroup of extracranial aneurysm models that demonstrated growth and potential rupture during follow-up. Methods. The literature was searched in Medline/Pubmed to identify extracranial in vivo saccular aneurysm models featuring growth and rupture, using a predefined search strategy in accordance with the PRISMA guidelines. From eligible studies we extracted the following details: technique and location of aneurysm creation, aneurysm pouch characteristics, time for model creation, growth and rupture rate, time course, patency rate, histological findings, and associated morbidity and mortality. Results. A total of 20 articles were found to describe growth and/or rupture of an experimentally created extracranial saccular aneurysm during follow-up. Most frequent growth was reported in rats (n = 6), followed by rabbits (n = 4), dogs (n = 4), swine (n = 5), and sheep (n = 1). Except for two studies reporting growth and rupture within the abdominal cavity (abdominal aortic artery; n = 2) all other aneurysms were located at the neck of the animal. The largest growth rate, with an up to 10-fold size increase, was found in a rat abdominal aortic sidewall aneurysm model. Conclusions. Extracranial saccular aneurysm models with growth and rupture are rare. Degradation of the created aneurysmal outpouch seems to be a prerequisite to allow growth, which may ultimately lead to rupture. Since it has been shown that the aneurysm wall is important for healing after endovascular therapy, it is likely that models featuring growth and rupture will gain in interest for preclinical testing of novel endovascular therapies.

The article analyzed the results of surgical treatment of 140 patients with surgery of abdominal aortic aneurism. The comparison group consisted of 80 patients with aortic aneurism more than 4,5 cm, who didn’t undergo surgery. The conventional method of Khardi-Pokrovskiy resection was complemented by a number of surgical methods in these cases. The results of surgery were improved due to application of these methods. All the patients (100%), who didn’t undergo surgery, passed away during 5 years, though 70% of them died because of aneurysm rupture. The early postoperative lethality was 5% in the main group, but 5-year survival was 81%.

Abstract:
Introduction. Splanchnic artery aneurysms are uncommon but important vascular entity because nearly 25% of all cases present as surgical emergency. Objective. The purpose of our study was to present nine patients operated on at the Institute of cardiovascular diseases, as well as literature review of clinical presentation of the disease. Method. There were three splenic artery aneurysms, two celiac trunk aneurysms, and one aneurysm of the hepatic, superior mesenteric, inferior mesenteric and gastroduodenal artery. All patients were males, mean aged 67.5 years (60-73). In four patients, splanchnic artery aneurysm was discovered accidentally during routine ultrasonographic and angiographic examinations of the abdominal aorta. At that time, arteriovenous fistula was diagnosed in a patient No 1; it was formed after rupture of the splenic artery aneurysm into the splenic vein. Three aneurysms were manifested by abdominal pain and palpable pulsating abdominal mass. Two patients were admitted as urgent cases in the state of hemorrhagic shock and signs of intraabdominal bleeding due to rupture of the splenic and hepatic arteries. In 7 cases, diagnosis was made preoperatively by means of ultrasonography and angiography; in two patients, accurate diagnosis was confirmed during surgery. Results. Proximal and distal ligation of the artery was performed in a patient with rupture of the splenic aneurysm into the splenic vein that caused arteriovenous fistula. Gastroduodenal artery aneurysm was treated by trans-aneurysmatic ligation of its "entering" and "exiting" branches. Aneurysms of distal part of the superior mesenteric and splenic artery were resected without further reconstruction. Partial resection of the aneurysm and endoaneurysmorrhaphy was carried out in one case of celiac trunk aneurysm, and in another, after aneurysm resection, the restoration of blood flow through the hepatic and lienal artery was achieved by Dacron grafts. In a patient with the inferior mesenteric artery aneurysm, the resection of aneurysm was followed by reimplantation of medial part of the artery into bifurcated Dacron graft which replaced abdominal aorta. In 5 patients, some of additional surgical procedures were performed. There were 4 reconstructive procedures of abdominal aorta and one splenectomy. The patient with ruptured hepatic artery aneurysm died during surgery due to uncontrolled hemorrhage. In other patients, there was neither morbidity nor mortality in the early postoperative period (first 30 days after surgery). Mean follow up was 1 to 5 years (mean 3.4 years). One patient died after 5 years due to myocardial infarction. CONCLUSION Although the introduction of precise diagnostic procedures (computerized tomography, magnetic resonance imaging, spiral scan) make diagnosis easier, the splanchnic artery aneurysms are still difficult to detect due to their uncommon clinical presentations.

Abstract:
Iliac artery aneurysm rupture can be rapidly fatal if not diagnosed immediately. These aneurysms usually present in patients with other aneurysmal diseases of the aortoiliac arterial system. If not diagnosed and surgically repaired, iliac artery aneurysms can proceed to expand and ultimately rupture, usually presenting with back, flank, or abdominal pain and, possibly, signs of systemic shock. We present an unusual case report of a common iliac artery aneurysm rupture presenting as gross hematuria due to an arteriovesical fistula. Only three other cases of arteriovesical fistulae have been reported previously. Unlike the case presented, all three of these cases involved trauma or surgical instrumentation or manipulation of the bladder.

Abstract:
Object. This study was conducted to investigate the familial and genetic contribution to intracranial, abdominal aortic, and all other types of aneurysms, and to define familial relationships among patients who present with the different aneurysm types. Methods. The authors used a unique Utah resource to perform population-based analysis of the familial nature of aneurysms. The Utah Population Data Base is a genealogy of the Utah population dating back eight generations, which is combined with death certificate data for the state of Utah dating back to 1904. Taking into account the genetic relationships among all aneurysm cases derived from this resource, the authors used a previously published method to estimate the familiality of different aneurysm types. Using internal, birth-cohort-specific rates of disease calculated from the database, they estimated relative risks by comparing observed to expected rates of aneurysm incidence in defined sets of relatives of probands. Conclusions. Each of the three aneurysm types investigated showed significant evidence for a genetic component. Relatives of patients with intracranial aneurysms do not appear to be at increased risk for abdominal or other lesions, but relatives of patients with abdominal aortic aneurysms appear to be at increased risk for other types of these lesions.

Abstract:
Chronic-contained rupture of an aortic aneurysm is a rare subset of ruptured aneurysms. The presentation is unusual, and the diagnosis is frequently delayed. Here, we describe a case of contained rupture of abdominal aortic aneurysm that presented with signs and symptoms of femoral neuropathy. Clinical and radiological findings were initially misinterpreted. The correct diagnosis was formulated belatedly, causing a progressively increased risk of fatal events. Surgical aortic repair was performed and the postoperative course was uneventful. In conclusion, in the presence of a retroperitoneal mass, a diagnosis of chronic-contained rupture of an abdominal aortic aneurysm should be considered.

Abstract:
Introduction: Diabetes mellitus appears to be negatively associated with abdominal aortic aneurysm; however, the mechanisms underlying this relationship remain poorly understood. The aim of this article is to provide a comprehensive review of the currently understood biological pathways underlying this relationship. Methods: A review of the literature (‘diabetes’ OR ‘hyperglycaemia’ AND ‘aneurysm’) was performed and relevant studies grouped into biological pathways. Results: This review identified a number of biological pathways through which diabetes mellitus may limit the presence, growth and rupture of abdominal aortic aneurysms. These include those influencing extracellular matrix volume, extracellular matrix glycation, the formation of advanced glycation end-products, inflammation, oxidative stress and intraluminal thrombus biology. In addition, there is an increasing evidence to suggest that the medications used to treat diabetes can also limit the development and progression of abdominal aortic aneurysms. Conclusion: The negative association between diabetes and abdominal aortic aneurysm is robust. Future studies should attempt to target the pathways identified in this review to develop novel therapeutic agents aimed at slowing or even halting aneurysm progression.

Abstract:
CONTEXT: Abdominal aortic aneurysm is an asymptomatic but potentially fatal condition. Elective surgery can prevent death from rupture, and is indicated for aneurysms larger than 45 mm. Because aneurysms tend to grow with time, detection of small ones (> 29 mm) may lead to a closer follow-up of patients at risk. OBJECTIVE: To determine the prevalence of abdominal aortic aneurysms in São Paulo, Brazil. DESIGN: Prospective, descriptive. SETTING: University Hospital. PARTICIPANTS: Persons aged 50 years or more were offered, through the press, the opportunity to be screened for abdominal aortic aneurysm. The total number screened was 2,756. PROCEDURE: All were submitted to abdominal palpation and ultrasound examination. PARAMETER STUDIED: A maximum diameter of 30 mm or more was considered to be an aneurysm. RESULTS: Sixty-four aneurysms were detected, nine of which measuring more than 49 mm. Palpation detected 60 aneurysms, but only 20 of these were confirmed by the ultrasound. Conversely, 41 of the ultrasound-detected aneurysms were not palpable. The percentages of abdominal aortic aneurysms found in the subgroups via ultrasound examination (with 95% confidence interval) were as follows: total group, 2.3 (1.8-3); men, 4.6 (3.5-5.9); women, 0.6 (0.3-1.1); men aged 60 or more, 6 (4.3-8); women aged 60 or more, 0.9 (0.4-1.8). CONCLUSION: In São Paulo, Brazil, 1.8 to 3 % of persons aged 50 years or more are expected to have abdominal aortic aneurysms. In the subgroup of men aged 60 or more, the expected prevalence is between 4.3 and 8%.

Abstract:
Purpose: To assess the effect of abdominal aortic aneurysm (AAA) size on overall aneurysm morphology with special attention to possible relationships among various anatomic variables that determine the feasibility of endovascular repair. Methods: One hundred sixty-eight patients were assessed with spiral computed tomographic angiography to measure the length and diameter of the AAA, the proximal neck, and the common iliac arteries. Anatomic variables were correlated with aneurysm size using Spearman's rank order correlation coefficients (rs); comparisons among small, intermediate, and large aneurysms were made using the Chi-square test. Results: Correlations between aneurysm size and the anatomic variables above were weak. The strongest association was between aneurysm size and aortic length (rs = 0.41, p < 0.001). Subgroup analysis showed no difference in proximal neck length, neck diameter, or overall suitability for endovascular repair between aneurysms greater or smaller than 5.5-cm diameter. However, significantly more short (< 1.5 cm), wide (> 3 cm), and, hence, unsuitable proximal necks were found in patients with aneurysms > 7 cm in diameter (χ2 = 7.8, p < 0.01). Conclusions: Shortening and widening of the proximal neck seems to increase with aneurysm size but only after the aneurysm expands beyond 7 cm in diameter. Aneurysms with diameters in the 4.5- to 5.5-cm range are no more suitable for endovascular repair than those between 5.5 and 7 cm. The lack of any significant correlation between anatomic variables emphasizes the need for accurate preoperative assessment of the anatomy of each individual patient before endovascular repair.
