Abstract:

Resumen La oclusión del TPI es poco observada durante la realización de angioplastia primaria en infarto agudo de miocardio, posiblemente en parte por la baja probabilidad de sobrevivir al evento el tiempo suficiente para llegar a un hospital (1). Reportamos cinco casos de pacientes tratados con angioplastia primaria con presentación y evolución clínica diferentes. Palabras clave: Infarto con elevación del ST, angioplastia primaria, oclusión aguda del tronco principal izquierdo. Abstract The left main trunk occlusion is rarely observed during primary angioplasty in acute myocardial infarction, possibly in part by the low probability of surviving the event long enough to reach a hospital. We report five cases of patients treated with primary angioplasty with different clinical presentation and course. Keywords: ST-elevation infarction, primary angioplasty, acute occlusion of the left main trunk.

Abstract:

Stenosis Aterosklerosis Intrakranial (ICAS) adalah penyebab umum Transient Ischemic Attack (TIA) dan stroke iskemik yang merupakan penyebab kematian nomor dua di dunia. Hingga 40 - 50%, tingkat ICAS simptomatik secara signifikan lebih tinggi pada populasi Asia dan mungkin merupakan penyebab paling umum dari stroke di seluruh dunia. Indikasi untuk perawatan endovaskular merupakan tantangan dan pemilihan bahan serta teknik intervensi pada dasarnya berbeda dari pengobatan stenosis ekstrakranial. Prosedur konservatif (perubahan medis dan gaya hidup) dan terapi endovaskular serta pendekatan terapi endovaskular (angioplasti balon perkutan (PTA) atau angioplasti stent-assisted (PTAS)) tersedia untuk perawatan ICAS. Tinjauan pustaka ini bertujuan untuk menevaluasi peran angioplasty sebagai tatalaksana dari stenosis aterosklerosis intrakranial. Perawatan endovaskular, seperti balloon angioplasty dengan atau tanpa stenting, telah muncul sebagai pilihan terapeutik untuk stenosis intrakranial simtomatik. Ada banyak jenis teknik endovaskular yang tersedia untuk perawatan ICAS, termasuk balloon angioplasty, ballon – mounted stent (Pharos Vitesse), dan self – expandable stent (Wingspan), masing-masing memiliki fitur dan keunggulan spesifik yang berkaitan dengan lesi arteri intrakranial yang berbeda. Maka dari itu, terapi endovascular pada pasien ICAS dapat dipertimbangkan sebagai alternatif untuk mencegah TIA/stroke iskemik berulang. Tindakan endovaskular membutuhan pertimbangan yang komprehensif dan persiapan multidisiplin agar dapat memberikan pelayanan yang efektif untuk pasien.

Abstract:

Background and objectives: Coarctation of aorta is the fourth most prevalent heart disease in infants requiring catheterization and surgery during the first year of life. Unfortunately, the initial clinical manifestations in infants are non-specific and mainly consist of tachypnea, poor feeding, and failure to thrive which result in delays in the correct diagnosis and therapeutic interventions. The aim of the study was to assess the immediate and intermediate outcome of balloon angioplasty in neonatal-type coarctation of aorta. Methods: It is a case series study of 13 young infants with neonatal coarctation of aorta their ages were between 10 days to 18 months and were admitted to intensive care unit of pediatric teaching hospital and Shar Hospital neonatal care unit in Sulaimani. Balloon angioplasty was done for them in Sulaimani cardiac center between February 2014 to October 2017. Results: Balloon angioplasty was done for 13 young infants with good results in 10/13 cases without any complication. There were significant mean pressure gradient changes before and after the procedure (48 ± 18.57mmHg and 28.15 ±16.12mmHg, respectively). The complications of balloon angioplasty were divided into immediate complications which occurred within 24h post angioplastic procedure and included peripheral cyanosis1case (7.7%), small aneurysm formation 1 case(7.7%), and intermediate complications which occurred within 6 month of the angioplasty showed repeated dilatation of coarctation in 1 case (7.7%), while in 10 cases (76.9%) there were no any complications. Conclusions: Balloon angioplasty is a safe and effective treatment option in infants with coarctation of aorta; however, timely diagnosis and improvement in angioplasty techniques are necessary to improve the outcome.

Abstract:

Introduction: the AVERT study (“Aggressive lipid-lowering therapy compared with angioplasty in stable coronary artery disease”) compared aggressive cholesterol-lowering (with the statin atorvastatin) to angioplasty in patients with mild to moderate coronary artery disease. Aim: our aim was to investigate the economic consequence of high dose of atorvastatin vs percutaneous coronary revascularization followed by standard therapy in Italian patients with stable coronary artery disease Methods: clinical information were taken from the AVERT study. We conducted a cost-effectiveness analysis, comparing high dose of atorvastatin (80 mg/die) versus angioplasty in the perspective of the Italian National Health Service. We identified and quantified medical costs: drug costs according to the Italian National Therapeutic Formulary and hospitalizations were quantified based on the Italian National Health Service tariffs (2006). Effects were measured in terms of mortality and morbidity reduction (number of deaths, life years gained and frequency of hospitalizations). We considered an observation period of 18 months. The costs borne after the first 12 months were discounted using an annual rate of 3%. We conducted one and multi-way sensitivity analyses on unit cost and effectiveness. We also conducted a threshold analysis. Results: the cost of atorvastatin therapy or angioplasty over the 18 months period amounted to approximately 779 euro and 5.5 millions euro per 1,000 patients respectively. Atorvastatin was more efficacious compared to angioplasty and the overall cost of care per 1,000 patients over 18 months of follow-up was estimated at 1.8 millions euro in the atorvastatin group and 7.2 millions euro in the angioplasty group, resulting into a cost saving of 5.4 millions euro that is 74,9% of total costs occurred in the angioplasty group. Discussion: this study demonstrates that high does atorvastatin treatment leads to a reduction of direct costs for the National Health System if compared to angioplastic treatment. Atorvastatin therapy is dominant since it is both less costly and more effective than angioplasty. Results of sensitivity analysis showed that atorvastatin therapy remains dominant even in the most unfavourable hypotheses.

Abstract:

Objectives The aim of this report is to assess the safety of endovascular treatment for chronic cerebrospinal venous insufficiency (CCSVI). Although balloon angioplasty and stenting seem to be safe procedures, there are currently no data on the treatment of a large group of patients with this vascular pathology. Methods A total of 564 endovascular procedures (balloon angioplasty or, if this procedure failed, stenting) were performed during 344 interventions in 331 CCSVI patients with associated multiple sclerosis. Results Balloon angioplasty alone was performed in 192 cases (55.8%), whereas the stenting of at least one vein was required in the remaining 152 cases (44.2%). There were no major complications (severe bleeding, venous thrombosis, stent migration or injury to the nerves) related to the procedure, except for thrombotic occlusion of the stent in two cases (1.2% of stenting procedures) and surgical opening of femoral vein to remove angioplastic balloon in one case (0.3% of procedures). Minor complications included occasional technical problems (2.4% of procedures): difficulty removing the angioplastic balloon or problems with proper placement of stent, and other medical events (2.1% of procedures): local bleeding from the groin, minor gastrointestinal bleeding or cardiac arrhythmia. Conclusions The procedures appeared to be safe and well tolerated by the patients, regardless of the actual impact of the endovascular treatments for venous pathology on the clinical course of multiple sclerosis, which warrants long-term follow-up.

Abstract:

Clinical success of percutaneous transluminal coronary angioplasty is limited by restenosis within months of the initial intervention. A number of vasoactive mediators and growth factors have been reported to participate in this process. The aim of the present experiments was to examine the effects of nonselective neutral endopeptidase (NEPi)/endothelin-converting enzyme (ECEi) inhibitors against neointimal proliferation (NIP) following balloon angioplasty of the left carotid artery of SpragueDawley rats with the right vessel serving as the uninjured control. The rats were divided in several groups: group 1, nontreated (vehicle); group 2, treated with a selective NEPi i.p.; groups 37, treated with nonselective NEPi/ECEi either i.p., s.c., i.v., or p.o. at various doses. After 2 weeks, cross-sectional histopathological and morphometrical examination of the left carotids revealed a severe NIP in vehicle-treated angioplastic rats compared with the control uninjured right carotid of the same rats. The selective NEPi CGS 24592 had no significant effect on restenosis, nor did the dual NEPi/ECEi CGS 26303 at 5 mg·kg1·day1 i.p. Both s.c and i.v. NEPi/ECEi treatment (10 mg·kg1·day1 b.i.d. s.c. or 10 mg·kg1·day1 i.v.) reduced NIP by up to 35%. The prodrug CGS 26393 (p.o.) also attenuated NIP by 23%. Plasma concentrations of these compounds correlated with the degree of inhibition. These data support the participation of the endothelin system in the rat model of balloon angioplasty and suggest that selective ECEi may be effective.Key words: endothelin, endothelin-converting enzyme, neutral endopeptidase, neprilysin, inhibitors, balloon angioplasty, neointimal proliferation.

Abstract:

Balloon angioplasty is often performed for symptomatic vasospasm following aneurysmal subarachnoid hemorrhage. Angioplasty of the anterior cerebral artery (ACA), however, is perceived to be a challenging endeavor and not routinely performed due to technical and safety concerns. Here, we evaluate the safety and efficacy of balloon angioplasty of the anterior cerebral artery for vasospasm treatment. Patients with vasospasm following subarachnoid hemorrhage who underwent balloon angioplasty at our institution between 2011 and 2016 were retrospectively reviewed. All ACA angioplasty segments were analyzed for pre- and post-angioplasty radiographic measurements. The degree of vasospasm was categorized as mild (<25%), moderate (25–50%), or severe (>50%), and relative change in caliber was measured following treatment. Clinical outcomes following treatment were also assessed. Among 17 patients, 82 total vessel segments and 35 ACA segments were treated with balloon angioplasty. Following angioplasty, 94% of segments had increased caliber. Neurological improvement was noted in 75% of awake patients. There were no intra-procedural complications, but two patients developed ACA territory infarction, despite angioplasty treatment. We demonstrate that balloon angioplasty of the ACA for vasospasm treatment is safe and effective. Thus, ACA angioplasty should be considered to treat vasospasm in symptomatic patients recalcitrant to vasodilation infusion therapy.

Abstract:

✓ To define the pathological effects of angioplasty on vasospastic arteries, 36 rabbits underwent angiography and induction of vasospasm by placement of blood-filled (vasospasm groups) or empty (control group) silastic sheaths around the cervical carotid arteries. Two (Day 2) or 7 days (Day 7) later, angiography was repeated and one carotid artery in each animal was dilated by balloon angioplasty. The rabbits were sacrificed 1 day, 7 days, or 3 to 4 weeks after angioplasty. Significant vasospasm developed after placement of silastic sheaths with blood (mean reductions in diameter 39% ± 6% at Day 2 and 48% ± 5% at Day 7). Arterial narrowing was less apparent in the control groups at Day 2 (24% ± 7%). Angioplasty performed on Day 2 significantly increased arterial diameters of vasospastic arteries (50% ± 7%; p < 0.05) but not those of control arteries (10% ± 6%, p > 0.05). Angioplasty performed on Day 7 increased the arterial diameters by a similar degree (47% ± 13%, not significant). Arteries remained dilated after angioplasty, although there was significant vasospasm 7 days after angioplasty when angioplasty was performed on Day 2. Blinded, semiquantitative histopathological study of the arteries showed that 3 to 4 weeks after angioplasty, there was significant endothelial proliferation and a trend for thinning of the tunica media. There were no significant changes in control arteries subjected to angioplasty. Angioplasty was not associated with significant arterial fibrosis as measured by hydroxyproline content (analysis of variance). The increase in endothelial proliferation and decrease in the thickness of the tunica media suggest that, in the rabbit model, angioplasty damages endothelial and smooth-muscle cells. This may be the basis for the observation that vasospastic arteries do not reconstrict after angioplasty.

Abstract:

Introduction: Arteriovanous (AV) access failure is one of the main problems in patients with end stage renal disease (ESRD), who receive hemodialysis. Balloon angioplasty is a favorable method for managing vascular access failure. The purpose of this study was to compare the six-month efficacy of paclitaxel-eluting balloon and plain balloon angioplasty in failed AV access cases among hemodialysis patients. Methods: In this quasi-experimental study (http://en.irct.ir/trial/35333), 50 hemodialysis patients with failure of AV access (stenosis > 50%), who were candidates for angioplasty, were included. They were divided to receive either paclitaxel-eluting balloon (25 patients) or plain balloon (25 patients) angioplasty. Patients were followed up for six months with color Doppler ultrasonography and clinical examination for the hemodynamic success rate of angioplasty. Results: After six months, 19 patients (76%) in paclitaxel-eluting balloon angioplasty group achieved hemodynamic success, which was significantly higher than plain balloon angioplasty group (13 patients, 52%) (P = 0.012). Age, gender, diabetes mellitus, hypertension, and location of AVF (snuff box, forearm, and antecubital fossa) did not associate with hemodynamic success rate in any group. Conclusion: The use of angioplasty with paclitaxel-eluting balloon was superior to plain balloon angioplasty for failed AV access cases in hemodialysis patients. It is recommended to use paclitaxeleluting balloon angioplasty in patients with failure of AV access and requirement for balloon angioplasty.

Abstract:

Background: Although percutaneous transluminal angioplasty has been established as a first-line therapy for access failure in dialysis, there are few reports on primary patency after percutaneous transluminal angioplasty. We investigated factors associated with primary patency following the first percutaneous transluminal angioplasty performed after vascular access construction in patients with arteriovenous fistula, including blood flow volume before and after percutaneous transluminal angioplasty and previously reported factors. Methods: We used medical records at six dialysis centers to retrospectively identify and analyze prognostic factors for primary patency after percutaneous transluminal angioplasty in 159 patients with arteriovenous fistula who underwent initial percutaneous transluminal angioplasty after vascular access construction. Results: Multivariate analysis with the Cox proportional hazard model showed that primary patency after percutaneous transluminal angioplasty in patients with arteriovenous fistula was significantly associated with lesion length (hazard ratio, 1.76; 95% confidence interval, 1.01–3.07; P = 0.045), and blood flow volume after percutaneous transluminal angioplasty (hazard ratio, 0.71; 95% confidence interval, 0.60–0.84; P < 0.001). When blood flow volume after percutaneous transluminal angioplasty was classified into three categories, risks of outcome events defining the end of primary patency after percutaneous transluminal angioplasty were significantly lower for 400–630 mL/min (hazard ratio, 0.38; 95% confidence interval, 0.21–0.68; P = 0.001) and >630 mL/min (hazard ratio, 0.16; 95% confidence interval, 0.06–0.40; P < 0.001) compared with <400 mL/min. Conclusion: Our study showed that blood flow volume after percutaneous transluminal angioplasty is an important prognostic factor for primary patency after percutaneous transluminal angioplasty in patients with arteriovenous fistula.

Abstract:

Abstract OBJECTIVE To compare the short- and long-term rates of stroke-and/or-death associated with primary angioplasty alone and angioplasty with stent placement using a meta-analysis of published studies. Both primary angioplasty alone and angioplasty with stent placement have been proposed as treatment strategies for symptomatic intracranial atherosclerotic disease to reduce the risk of stroke-and/or-death with best medical treatment alone. However, it remains unclear which of these endovascular techniques offers the best risk reduction. METHODS We identified pertinent studies published between January 1980 and May 2008 using a search on PubMed and Cochrane libraries, supplemented by a review of bibliographies of selected publications. The incidences of stroke-and/or-death were estimated for each report and pooled for both angioplasty alone and angioplasty with stent placement at 1 month and 1 year postintervention and then compared using a random-effects model. The association of year of publication and 1-year incidence of stroke-and/or-death was analyzed with meta-regression. RESULTS After applying our selection criteria, we included 69 studies (33 primary angioplasty-alone studies [1027 patients] and 36 studies of angioplasty with stent placement [1291 patients]) in the analysis. There were a total of 91 stroke-and/or-deaths reported in the angioplasty-alone–treated group (8.9%; 95% confidence interval [CI], 7.1%–10.6%), compared with 104 stroke-and/or-deaths in the angioplasty-with-stent–treated group (8.1%; 95% CI, 6.6%–9.5%) during a 1-month period (relative risk [RR], 1.1; P = 0.48). The pooled incidence of 1-year stroke-and/or-death in patients treated with angioplasty alone was 19.7% (95% CI, 16.6%–23.5%), compared with 14.2% (95% CI, 11.9%–16.9%) in the angioplasty-with-stent–treated patients (RR, 1.39; P = 0.009). The incidence of technical success was 79.8% (95% CI, 74.7%–84.8%) in the angioplasty-alone group and 95% (95% CI, 93.4%–96.6%) in the angioplasty-with-stent–treated group (RR, 0.84; P < 0.0001). The pooled restenosis rate was 14.2% (95% CI, 11.8–16.6%) in the angioplasty-alone group, as compared with 11.1% (95% CI, 9.2%–13.0%) in the angioplasty-with-stent–treated group (RR, 1.28; P = 0.04). There was no effect of the publication year of the studies on the risk of stroke-and/or-death. CONCLUSION Risk of 1-year stroke-and/or-death and rate of angiographic restenosis may be lower in symptomatic intracranial atherosclerosis patients treated by angioplasty with stent placement compared with patients treated by angioplasty alone.

Abstract:

Introduction Subclavian stenosis has a prevalence of approximately 2% in the community, and 7% within a clinical population. It is closely linked with hypertension and smoking. There is a relative paucity of published data to inform clinicians on the optimal mode of treatment for subclavian artery stenosis. Objectives To compare clinical outcomes of subclavian bypass surgery with that of subclavian endovascular re-vascularisation. Endpoints were survival time, re-intervention-free survival, and symptom-free survival. Method In all, 21 subclavian interventions were performed from 2000 to 2010. We compared angioplasty vs angioplasty with stenting vs bypass. Results Technical success was 100% in all groups. Symptom-free survival, at 70 months, was 60% in the angioplasty group, 100% in the angioplasty and stenting group and 75% in the bypass group. Re-intervention rate was 40% in the angioplasty group, 0% in the angioplasty and stenting group and 25% in the bypass group. Median time for re-intervention was 9.5 months in angioplasty patients and 36 months in bypass patients ( p = 0.102). Target lesion revascularisation was 20.0% for angioplasty procedures, 16.67% for angioplasty and stenting and 25% for bypass procedures. Conclusion Angioplasty with stenting provides improved symptom-free survival and freedom from re-intervention in patients with symptomatic subclavian artery stenosis.
