Resumen

Environ deux tiers des patients atteints de syndrome de détresse respiratoire aiguë (SDRA) présenteront une instabilité hémodynamique avec recours aux vasopresseurs. Sous ventilation mécanique, la diminution de précharge du ventricule droit (VD) suite à l’augmentation de la pression pleurale et l’augmentation de la postcharge du VD secondaire à l’élévation de la pression transpulmonaire seront des phénomènes exacerbés en cas de SDRA. Les risques encourus sont une diminution du débit cardiaque global et l’évolution vers un cœur pulmonaire aigu (CPA). Le contrôle de la pression motrice, de la pression expiratoire positive et la lutte contre l’hypoxémie et l’hypercapnie auront un impact autant respiratoire qu’hémodynamique. L’échographie cardiaque tient un rôle central au sein du monitorage hémodynamique au cours du SDRA, à travers l’évaluation du débit cardiaque, des différentes pressions de remplissage intracardiaques et le diagnostic de CPA. Le cathéter artériel pulmonaire est un outil de monitorage complet, indiqué en cas de défaillance cardiaque droite ou hypertension artérielle pulmonaire sévère ; mais le risque d’effets indésirables est élevé. Les moniteurs utilisant la thermodilution transpulmonaire permettent un monitorage du débit cardiaque en temps réel et sont d’une aide précieuse dans l’évaluation du statut volumique. L’évaluation de la précharge dépendance ne doit pas s’effectuer sur les variabilités respiratoires de la pression pulsée ou du diamètre des veines caves, mais à travers l’épreuve de lever de jambe passif, le test d’occlusion télé-expiratoire ou encore les épreuves de remplissage titrées.

Resumen

The gold-palladium mineralization of the Chudnoe deposit is represented by mineralized veined zones in fractured and brecciated rhyolites of the Riphean-Vendian age. Native gold and palladium minerals are concentrated mainly in veins of Cr-containing muscovite (fuchsite), in which allanite is present in small amounts; quartz, albite, calcite, potassium feldspar, titanite, apatite, zincochromite and other minerals are also found. Veins of allanite-albite-quartz composition are found in ore zones, in some cases containing abundant fuchsite secretions. It has been established that quartz-albite-allanite-fuchsite and other fuchsite-containing veins are the result of the superposition of quartz-albite vein execution on previously formed gold-bearing fuchsite veins. Quartz-albite vein material fills central parts of the combined veins and cements fragments (xenoliths) of fuchsite, while in some cases part of the gold was redeposited and fixed in the quartz-albite part of the veins. Based on the study of the decomposition structures of solid solutions in native gold, it was previously established that the temperature of gold formation in fuchsite veinlets exceeded 220 °C. The deposition temperature of the main part of the quartz-albite veins was noticeably lower. The homogenization temperature of fluid inclusions in vein minerals (quartz, albite, allanite, calcite) was mainly in the range of 96—168 °C, solutions were enriched with magnesium and calcium chlorides. Under these conditions, allanite, apatite, monazite, xenotime, and molibdosheelite were formed and redeposited, and fuchsite recrystallized.

Resumen

Introduction : L’oreillette unique est une cardiopathie congénitale rare. Le traitement est la chirurgie. Son pronostic est bon après chirurgie. Le but de ce travail est de rapporter un cas d’oreillette unique. Observation : Nous rapportons l’observation d’une jeune femme âgée de 17 ans issue d’un mariage non consanguin sans antécédents, présentant depuis quelques mois une dyspnée d’aggravation progressive. L’examen physique avait révélé un souffle latérosternal de 5/6. La radiographie pulmonaire mettait en évidence une hyper vascularisation pulmonaire et un ICT à 0,60. Echocardiographie : oreillette unique, insuffisance tricuspide grade II, FE : 45 %, PAPS : 63 mm hg. Exploration per-opératoire : veine cave supérieure gauche se jetant dans un sinus coronaire dilaté de topographie anormale et oreillette unique par absence complète du septum interauriculaire. Elle a bénéficié de la fermeture de la communication inter auriculaire par un patch péricardique autologue sous circulation extracorporelle. Les suites post opératoires étaient simples. Conclusion : L’oreillette unique est une variété rare de communications inter-auriculaires caractérisée par l’absence du septum inter-auriculaire. Elle peut être isolée ou associée à d’autres cardiopathies congénitales.

Resumen

The prospective study was conducted from December 2022 to May 2023 to assess patient-based, radiological, and clinical outcomes after conventional surgery and radiofrequency ablation for great saphenous varicose veins. Patients were randomly divided to undergo conventional surgery or RFA. American Society of Anesthesiologists fitness grade, Venous Disability Score (VDS), Total Clinical Severity Score (TCSS), Michael's, and CEAP clinical classes were recorded. VEINES-QoL/Sym questionnaire and Aberdeen Varicose Vein Questionnaire were used to estimate baseline QoL. Patients were called for follow-up at the end of 1st and 5th week. The study was conducted on a total of 110 patients. Patients were randomly divided; 57 underwent RFA, and 53 underwent conventional surgery. Results showed that the difference between both groups regarding anesthesia induction, recovery, and discharge from surgery was insignificant. RFA had significantly longer total theater time compared to conventional surgery. Duplex imaging showed that RFA resulted in successful ablation except in two cases where veins had segmental brisk flow. These cases were retreated successfully. Conventional surgery only had the problem of incomplete stripping (6 cases). Post-operative pain, bruising, and the need for analgesia were significantly higher following conservative surgery. Patients in the RFA group returned to work and normal activities more quickly than the conventional surgery group. It is concluded that RFA had a longer intervention time but significantly better outcomes than conventional surgery.

Resumen

Dural arteriovenous fistulas (AVF) are rare intracranial vascular malformations, consisting of communications between dural venous arteries and sinuses, meningeal veins, cortical veins, or combinations thereof. In most cases the etiology is unknown. The clinical presentation is determined by the location and mainly by the drainage pattern. The recognition of this rare clinical entity is essential for an early diagnosis and intervention, to avoid the potentially serious complications of the disease, such as, intracranial hypertension, vascular dementia, hemorrhage, among others.

Resumen

We report our experience of 93 patients with recurrent varicose veins. Doppler ultrasound and ascending phlebology were routinely performed, with descending or popliteal phlebography in some patients, as a means of evaluating recurrence. Early recurrence was found in a few cases due to incorrect diagnosis. Late recurrence, in the majority of cases, was due to incorrect surgery or the overlooking of gastrocnemius vein incompetence. In some cases deep reflux, soleal arch compression or left iliac vein compression was found to be a possible cause of recurrence. Extensive evaluation of the venous disorder and the ligation of every site of deep to superficial reflux are the first steps in preventing recurrence. The rules and pitfalls of surgical treatment are stressed. On recurrence, Doppler ultrasound is accurate in deep venous assessment and in demonstrating leaking perforators. Ascending phlebography is the method of choice in the investigation of the deep veins and in confirming perforating vein incompetence. We have used popliteal phlebography to demonstrate incompetence of the LSV junction, SSV junction, gastrocnemius vein and mid-thigh and popliteal fossa perforators. When necessary, surgery for recurrent varicose veins must be carefully carried out according to certain basic principles.

Resumen

Klippel–Trenaunay–Weber syndrome (KTWS) is a congenital disorder characterized by a triad of varicose veins and venous malformation involving one or more extremities, cutaneous haemangioma, and hypertrophy of soft tissue and bone. The syndrome is rare and it usually presents as varicose veins or cutaneous naevi. We report a patient with KTWS who developed superficial thrombophlebitis in her varicose veins and died from a pulmonary embolism. To optimize management it is important to recognize the syndrome, and the patient should ideally be referred for multidisciplinary vascular care and all such patients should be anticoagulated in the long term.

Resumen

ABSTRACT Our study was performed on 21 cases, of which 12 were plastic casts and 9 were CT reconstruction. We found that, most frequently (68.75% of the cases), the pulmonary veins were formed by two roots, one superior and one inferior. In 28.13% of cases, the pulmonary veins were formed from three roots (superior, middle and inferior) and in only one case the superior right pulmonary vein had five roots. The venous roots confluence to form the corresponding trunk was at a distance of between 0.5-2 cm. The termination of the superior pulmonary veins was on the upper part of the anterior atrial wall, most commonly in its lateral side. The distance between the right pulmonary veins was between 0.4-3 cm. The inferior pulmonary veins ended on the infero-lateral part of the posterior atrial wall. The distance between the left pulmonary veins was 1.2-3.4 cm. Among the variation in number of the pulmonary veins we met: three cases with three right pulmonary veins and one case when the inferior right pulmonary vein joined terminally the inferior left pulmonary vein, forming a single venous trunk. Supplementary pulmonary veins were encountered only on the right; in one case there were two posterior right pulmonary veins (superior and inferior), in the second case were anterior right pulmonary veins (superior and inferior) and in a third case were three veins, superior, middle and inferior

Resumen

Objectives To evaluate the clinical presentation and disease course of symptomatic plantar vein thrombosis. Patients and methods Patients with a first diagnosis of symptomatic plantar vein thrombosis at our institution were retrospectively identified from a prospectively maintained database. All patients underwent complete venous compression sonography extended to the plantar veins because of local symptoms at the sole of the foot. Clinical characteristics were obtained from the medical records. Results Between 2005 and 2013, 22 patients were diagnosed with a first episode of plantar vein thrombosis (64% women, mean age at diagnosis 58.2 years, range 32–79 years). All patients reported moderate to heavy pain of the sole of the foot. The lateral plantar veins (96%) were more frequently affected than the medial plantar veins (41%) and extension into the deep calf veins was common (27%). Half of the episodes were idiopathic, with subsequent diagnosis of occult malignancy in two of these patients. In seven patients (32%), plantar vein thrombosis occurred in association to physical strain to the foot. All patients were treated with anticoagulation. Symptomatic pulmonary embolism was not observed and during a mean follow up of 21 months, the post-thrombotic syndrome did not occur. However, recurrences were common (27%) and frequently again affected the plantar veins. Conclusion Plantar vein thrombosis should be considered as an important differential diagnosis of acute foot pain.

Resumen

Abstract BACKGROUND AND IMPORTANCE: Prompt diagnosis of intracranial dural arteriovenous shunt (DAVS) with spinal venous drainage, classified as Cognard type V, is difficult. We investigated the angiographic and magnetic resonance imaging (MRI) characteristics of Cognard type V DAVS to determine the reason for the difficulty in early diagnosis. CLINICAL PRESENTATION: We systematically reviewed 54 published and 3 new cases of Cognard type V DAVS. The pattern of venous drainage was classified on the basis of relative dominance of the anterior and posterior spinal veins with the use of angiograms. T2-weighted sagittal MRIs were used to detect signal flow voids of enlarged spinal veins. Types of venous drainage were determined in 49 of the 57 cases. Twenty-eight and 8 cases showed a dominance of anterior and posterior spinal venous drainage, respectively. In 13 cases, venous drainage was equally distributed through the anterior and posterior spinal veins. Of 41 cases with an abnormally dilated anterior spinal vein, MRIs were available for 25 cases. Signal flow voids of enlarged anterior spinal veins were detected in 9 cases (36.0%), whereas dilatation of the posterior spinal veins was apparent in 9 of 16 cases (56.3%). Overall, MRI detected enlargement of either anterior or posterior spinal veins in 15 of 41 cases (36.6%). CONCLUSION: In Cognard type V DAVS, anterior venous drainage is dominant. Because the anterior spinal veins are located subpially, flow voids are less prominent on sagittal T2-weighted MRI. This may lead to difficulties in diagnosing. Evaluation with MR angiography may compensate for these limitations.

Resumen

The study objective is to investigate the pathogenesis of the development of pelvic symptoms in patients with pelvic varicose veins.Materials and methods. From 2015 to 2022, 145 men with pelvic varicose veins were examined. The examination included questioning of patients using questionnaires (scales) and instrumental methods: 1) ultrasound examination of the scrotum with color Doppler mapping; 2) transrectal ultrasound examination of the prostate and veins of the periprostatic plexus; 3) magnetic resonance imaging of the inferior vena cava and pelvic vessels or computer (multispiral) tomography of the abdominal organs with contrast; 4) phlebography of the renocaval and ileocaval segments.Results. The variant anatomy of fibrous and fibro-osseous canals (tunnels) can explain the fact that with equally pronounced expansion of the pelvic veins, some patients have pelvic symptoms due to nerve compression, while the other part does not. This concept is supported by the fact that in those patients who had complaints of pain, dysuria and erectile dysfunction, after surgical treatment of pelvic varicose veins, in most cases they disappeared or decreased.Conclusion. Pain syndrome (56.6 % of cases), erectile dysfunction (51 % of cases) and dysuria (17.9 % of cases) were noted as clinical manifestations in patients with pelvic varicose veins. Analysis of data after examination and treatment of patients with pelvic varicose veins allowed us to identify “venous compression neuropathy syndrome” as a probable cause of the development of pelvic symptoms in patients with pelvic varicose veins. Depending on the level of localization of nerve compression by varicose veins, we proposed to distinguish three forms of this syndrome: 1) thoracic, 2) lumbar, and 3) sacral form.

Resumen

The authors present 2 cases of cervical myelopathy produced by engorged vertebral veins due to overshunting. Overshunting-associated myelopathy is a rare complication of CSF shunting. Coexisting cervical degenerative disc disease may further increase the difficulty of diagnosing the condition. Neurosurgeons and others who routinely evaluate patients with intracranial shunts should be familiar with this rare but possible diagnosis.

Resumen

During reviewing cases with AVM, the author noticed that stenotic and occlusive changes of the draining veins are commonly seen in high flow cerebral AVMs. However, little attention has been paid to these venous diseases until ectatic veins, generated in the upstream of the venous system, cause mass effect to the surrounding structures, or redistribution and shunting toward regional veins became insufficient after they are markedly overloaded or occluded. Cases with such venous abnormality are clinically important because of the possibility of dramatic improvement of neurological deficits after embolization of AVMs. Following presenting treatment results of 177 AVM case, the author is going to present five cases with abnormality in the Galenic venous system and two cases with abnormality in cortical veins associating with high flow cerebral AVMs. Consideration will be made on symptomatology and pathophysiologic mechanism of venous abnormalities associating with high flow cerebral AVMs.

Resumen

Background: Varicose veins defined as dilated, tortuous, subcutaneous veins ≥3 mm in diameter, measured in the upright position with demonstrable reflux. Though the history of varicose veins dates prehistorically, the advances in diagnosis and new management modalities gained attention recently. The aim of the present study was to study the clinical profile, risk factors and their association, different types of surgical procedures employed and complications associated with varicose veins.Methods: A one year observational after ethical committee approval was conducted by department of general surgery at ACSR Medical College. Cases fulfilling the inclusion criteria were clinically examined and duplex ultrasound colour Doppler was performed for diagnosing the varicose veins and findings of site of incompetence was noted. All the cases were operated and followed up for six months period. The results were tabulated and analyzed in Microsoft Excel for any corrections.Results: Eighty cases with 66.25% males and 33.75% females with mean age of 40.24 years and majority (40%) were in 41 to 50 years group. 60% of cases had varices in right limb and long saphenous vein was involved in 52.5% of cases.85% had dilated veins, perforator incompetence was noted below the knee in 30% of cases. 41.25% of cases saphenofemoral flush ligation with stripping of long saphenous vein. Wound infection was the common postoperative complication.Conclusions: Operative line of management should be the first line of treatment even though conservative management relieves the symptoms but always requires a definitive management.

Resumen

Acute venous thromboembolism (VTE), including deep vein thrombosis (DVT) and pulmonary embolism (PE), is a common disorder with an annual incidence rate of 1-2 cases per 1000 persons. Health-related quality of life in patients after having DVT is impaired if not treated correctly. The VEINES - QOL (Sym) is a disease-specific instrument used to assess health-related quality of life in patients with chronic venous disease of the legs. A descriptive cross-sectional study was conducted on 32 patients diagnosed with deep vein thrombosis and treated at Vietnam National Heart Institute and Hanoi Medical University hospital. Our study indicated statistical differences in patients’ quality of life (QOL) before and one month after treatment. Mean difference for VEINES-QOL was 1.4 (p-value = 0.02), for VEINES-Sym was 1.6 (p-value = 0.01). Our study brought conclusions: anticoagulation therapy increased QOL in patients with DVT; and the principal factors influencing long-term QOL were oldage, BMI, recurrent DVT, and proximal DVT.

Resumen

Introduction: The number of elderly patients requiring hemodialysis has increased, along with the need for multiple vascular access placements. Thus, the frequency of access creation using the upper arm veins, including transposed basilic arteriovenous fistula, has also increased. The purpose of this study was to identify the prevalence of anatomical variations in the upper arm veins on preoperative mapping venography and to investigate the implications of such variants on access creation. Methods: A total of 494 venograms were performed on 251 patients for primary access creation from June 2014 to June 2017 in this single-center, retrospective study. The venograms were classified into eight subtypes, based on the anatomical relationship between the basilic and brachial veins. The presence of bifid cephalic arches and brachial–basilic ladders was also examined. Results: The presence of bifid cephalic arches and brachial–basilic ladders was identified in 8.7% and 14.0% of cases, respectively. Paired brachial veins joined separately with the basilic vein in 67.4% of venograms, whereas these veins merged into a common brachial vein before connecting to the basilic vein in 13.1% of cases. A single brachial vein was present in 19.3% of cases. 15.7% of cases were considered unsuitable for basilic vein transposition due to the early confluence of the brachial–basilic vein, posing a risk of obliterating the deep venous drainage if transposed. Conclusion: There are significant anatomical variations of upper arm veins, and the recognition of certain variants can affect surgical planning and outcomes of access placement. It is important to identify anatomical variants of the upper arm veins during preoperative vein mapping.

Resumen

Introduction. The development of modern surgery requires the advancement of expertise about individual characteristics of large vessels development. The expansion of surgical treatment options of liver diseases determines the necessity of more detailed information about the anatomy of the portal, biliary and arterial systems, and about the anatomy of the hepatic veins in particular.The aim of research was to study characteristics of the left hepatic vein formation based on ultrasound examination findings.Materials and methods. The study included 39 outpatients, 11 males and 28 females, aged 17-84. Using ultrasound imaging methods, the authors determined linear dimensions, variations and angles of junction of the veins forming the left hepatic vein.Results. The main six variations of the left hepatic vein were determined as follows: variation I was observed in 9 cases (23.1%), variation II - in 7 cases (17.9%), variation III - in 11 cases (28.2%), variation IV - in 6 cases (15.4%), variation V - in 5 cases (12.8%), variation VI - in 1 case (2.6%). The angle of junction of the veins I and III at the site of their entry into the main trunk of the venous system was from 19-21 degrees to 80-85 degrees; the angle of junction of the vein II was from 21 degrees to 61.6 degrees. Deviation of veins in the plane perpendicular to the rest veins ranged from 32 degrees to 81.7 degrees. Additional veins entered at the angles from 22.5 degrees to 45 degrees. When observing, the vein diameter for veins I and II was from 1.3 mm to 4.8 mm, and for vein III - from 1.5 mm to 3.5 mm. There were additional veins determined with an average diameter equal 2.25 mm 0.25 mm. The size of the trunk of the left hepatic vein directly corresponded to a diameter of 2 mm to 7.7 mm.Conclusion. The presented variations are of major importance for modern diagnostic methods, they also expand the understanding of the anatomical variations in the left lobar vein formation, which should be taken into account by surgeons during liver operations.

Resumen

Background: When performing partial toe-transfer flaps with a short vascular pedicle, as the flap becomes smaller, the likelihood of securing veins in the flap decreases. The purpose of this study was to clarify how frequently the partial toe-transfer flap with a short pedicle (free vascularized half-big toenail flap) contains veins and elucidate how frequently we can secure the veins with an artery via the first web space approach alone, using the Genial Viewer (a near-infrared light transmission imaging device). Methods: We observed the dorsal vein images of the bilateral big toes of 250 volunteers (male, n = 125; female, n = 125) using the device. We counted the total number of dorsal veins in the big toe, the veins that crossed the margin of the region equivalent to the half-big toenail flap, and the veins that branched off from the fibular side of the flap area. An unpaired Student’s t-test was used for the statistical analyses. Results: All of the dorsal big toes contained veins. The mean number of the veins was 2.3 (range, 1–4). Branched-off veins were observed in the area equivalent to the half-big toenail flap in 496 (99.2%) of the big toes, and the mean number of veins was 1.9 (range, 0–4). In four cases, the region contained no veins (unilaterally). Branched-off veins were observed in the first web space in 440 (88.0%) of the big toes, and the mean number of veins was 0.9 (range, 0–2). Conclusions: The present study indicated high consistency of the veins in partial toe-transfer flaps with a short vascular pedicle and the high possibility of harvesting a flap with only exposing the first web space. In addition, in most cases, the flap will include one or, at most, two veins in the first web space.

Resumen

Pulmonary veins carry oxygenated blood from the lungs to the left atrium. Variations are quite common in the pattern of drainage. The present study was undertaken to evaluate the incidence of different draining patterns of the right pulmonary veins at the hilum by dissecting the human fixed cadaveric lungs. Clinically, pulmonary veins have been demonstrated to often play an important role in generating atrial fibrillation. Hence, it is important to look into the anatomy of the veins during MR imaging and CT angiography. In 53.8% of cases, the right superior lobar vein and right middle lobar vein were found to be united together to form the right superior pulmonary vein. In contrast to this, in 11.53% of cases, right middle lobar vein united with the right inferior lobar vein to form the right inferior pulmonary vein, while in 26.9% of cases, the right superior lobar vein, right middle lobar vein, and right inferior lobar vein drained separately.

Resumen

The implantable catheter port is a permanent central venous access device typically used for long-lasting injectable treatments such as chemotherapy. Materials and Methods: We report a retrospective study spread over 6 years to identify 432 patients who benefited from the placement of an implantable catheter port. Patients were followed during hospitalization and at discharge, one month, and one year later. Results: The average age is 67.9 years. There are 284 women and 148 men. The primary cancer requiring the installation of a chamber is essentially represented by cancer and bronchopulmonary cancers. The right internal jugular approach was the most frequently performed. Complications are mainly represented by infection and pneumothorax. Discussion and Conclusion: For prolonged treatments or treatments with aggressive drugs for the veins, a central venous access is preferable to the short peripheral catheter because the repetition of the punctures and the venous irritation of certain injectable drugs expose to pain, thrombosis or even necrosis, peripheral veins. The implantable catheter chamber allows direct access to a vessel to position the end of the catheter at the entrance to the heart, therefore rapid blood dilution. This makes it possible to inject drugs over the long term and/or whose venous tolerance is poor. It is a quick and easy technique with low morbidity.

Resumen

Background and Objectives: The facial vein is the main collector of venous blood from the face. It plays an important role in physiological as well as pathological context. However, to date, only limited data on the course and tributaries of the facial vein are present in contemporary literature. The aim of this study was to provide detail on the course and the tributaries of the facial vein. Materials and Methods: In 96 sides of 53 body donors, latex was injected into the facial vein. Dissection was carried out and the facial vein and its tributaries (angular vein, ophthalmic vein, nasal veins, labial veins, palpebral veins, buccal and masseteric veins) were assessed. Results: The facial vein presented a textbook-like course in all cases and crossed the margin of the mandible anterior to the masseter in 6.8% of cases, while being located deep to the zygomaticus major muscle in all cases and deep to the zygomaticus minor in 94.6% of cases. Conclusions: This work offers detailed information on the course of the facial vein in relation to neighboring structures, which shows a relatively consistent pattern, as well as on its tributaries, which show a high variability.

Resumen

Spine vascular lesions like brain vascular lesions include spinal cord stroke, vascular malformation such as venous malformation or venous angioma, cavernous malformation, arteriovenous malformation or arteriovenous fistula. Embryogenesis of spinal vascular is the basic principle to understand the vascular malformation of the spine. This study aims to report serial cases with review of spinal vascular lesions. MR angiography techniques with contrast injection may reflect the direction of flow epidural veins to describe the site of arterial feeders. Serpiginous veins are commonly visible through the dorsal cord surface in MR myelography. The gold standard for diagnosing vascular malformation is Digital Subtraction Angiography (DSA). MRA helps to guide the location for DSA. Several cases are reported using MRA modalities and show the special location site of the spinal disorder.

Resumen

The modern approach to the treatment of chronic venous insufficiency and varicose veins utilizes physical techniques for endovasal obliteration. It is characterized by significantly fewer side effects and opens new possibilities for the treatment of patients with varicose disease. Purpose: To evaluate the effectiveness of radiofrequency obliteration of varicose veins and puncture laser obliteration of perforant veins in the combined treatment of patients with varicose disease (VD). Material and methods. Outcomes of treatment of 528 patients with VD in the pool of the great saphenous vein (GSV) or small saphenous vein (SSV) have been analyzed. These patients had the combined treatment, which included radiofrequency obliteration of GSV and SSV trunk and / or Giacomini vein. Of these, 335 patients had also ECHO Foam-Form sclero-obliteration of GSV and SSV inflows and perforant veins on the thigh and / or ankle. In 266 patients, their treatment was combined with miniphlebectomy of GSV and SSV inflows and perforant veins on the thigh and / or ankle; and in 55 patients – with puncture laser obliteration of perforant veins. Results. The assessment of curative outcomes have has shown that postoperative pain intensity (VAS) was 3.1 + 0.5. Transient paresthesias were seen in 14 (3.4%) cases. Local ecchymoses – in 18 (4.3%) cases. Consequences of tumescent anesthesia: local ecchymoses and hyposthesia passed after 3–5 days. Skin pigmentation was noted in 1 case and lasted up to 3 months. Thrombosis was registered in 2 cases as a parietal thrombus in the great saphenous vein at the level of the middle third of the thigh; and in 2 cases as a thrombotic clot prolapse.

Resumen

Background: The main purpose of pre-operative imaging in liver transplantation is to expose the arterial and venous vascular map. Prior to transplantation it is necessary to image the vascular structures property due to complex nature of liver vascular anatomy and its frequent variations. CT is a useful method not only in the determination of hepatic arterial anatomy, hepatic venous anatomy, accessory hepatic veins and portal veins variations.Methods: This was a prospective observational study performed at the department of surgery, Gandhi Medical College Bhopal and study of CECT was carried out in the department of radiodiagnosis with approval from college ethical committee on 100 patients during a period of 2 years from 2017 to 2019.Results: In study of 100 cases were studied. The study mainly done on the MHV mainly its length, width draining segments of liver by MHV and accessory hepatic veins. In overall cases maximum cases had drainage from segment IVb, V and segment VIII. The segment 5 accessory vein is the most common single accessory vein found in the study.Conclusions: Many parameters of MHV have studied in the study and understanding of these parameters is undoubtedly important for operating surgeon its anatomical draining patterns, draining liver segments and has got the presence of the various accessory veins in the liver. Recognition of these accessory hepatic veins is important because some of these accessory veins may become useful in segmental liver transplantation.

Resumen

Object The purpose of this paper is to evaluate whether venous indocyanine green (ICG) videoangiography has any potential for predicting the presence of a safe collateral circulation for veins that are at risk for intentional or unintentional damage during surgery. Methods The authors performed venous ICG videoangiography during 153 consecutive neurosurgical procedures. On those occasions in which a venous sacrifice occurred during surgery, whether that sacrifice was preplanned (intended) or unintended, venous ICG videoangiography was repeated so as to allow us to study the effect of venous sacrifice. A specific test to predict the presence of venous collateral circulation was also applied in 8 of these cases. Results Venous ICG videoangiography allowed for an intraoperative real-time flow assessment of the exposed veins with excellent image quality and resolution in all cases. The veins observed in this study were found to be extremely different with respect to flow dynamics and could be divided in 3 groups: 1) arterialized veins; 2) fast-draining veins with uniform filling and clear flow direction; and 3) slow-draining veins with nonuniform filling. Temporary clipping was found to be a simple and reversible way to test for the presence of potential anastomotic circulation. Conclusions Venous ICG videoangiography is able to reveal substantial variability in the venous flow dynamics. “Slow veins,” when they are tributaries of bridging veins, might hide a potential for anastomotic circulation that deserve further investigation.

Resumen

Abstract OBJECTIVE: The purpose of this study is to clarify whether venous compression on the trigeminal nerve really causes trigeminal neuralgia or not, and to identify which veins are the offending veins. METHODS: We used microvascular decompression in operations on 121 patients with typical trigeminal neuralgia. We analyzed the intraoperative findings and surgical results in these 121 cases. RESULTS: In 7 of the 121 cases, only the vein was identified as a compressive factor on the trigeminal nerve. In 6 of these 7 cases, single venous compression was found, whereas the remaining case had two offending veins. The transverse pontine vein was most frequently found as the offending vein near Meckel's cave. All patients showed complete relief of trigeminal pain after decompression of the veins, but four of them developed facial numbness after surgery, which tended to be slight and did not require any treatment. CONCLUSION: Our surgical experiences showed that venous compression could cause trigeminal neuralgia by itself and that the transverse pontine vein should be carefully observed because it is most frequently the offending vein.

Resumen

SummaryVenous thromboembolism [TE] is a multifactorial disease and antithrombin deficiency [ATD] constitutes a major risk factor. In the present study the prevalence of ATD and the clinical presentation at TE onset in a cohort of paediatric index cases are reported. In 319 un - selected paediatric patients (0.1–18 years) from 313 families, recruited between July 1996 and December 2013, a comprehensive thrombophilia screening was performed along with recording of anamnestic data. 21 of 319 paediatric patients (6.6%), corresponding to 16 of 313 families (5.1%), were AT-deficient with confirmed underlying AT gene mutations. Mean age at first TE onset was 14 years (range 0.1 to 17). Thrombotic locations were renal veins (n=2), cerebral veins (n=5), deep veins (DVT) of the leg (n=9), DVT & pulmonary embolism (n=4) and pelvic veins (n=1). ATD co-occurred with the factor- V-Leiden mutation in one and the prothrombin G20210A mutation in two children. In 57.2% of patients a concomitant risk factor for TE was identified, whereas 42.8% of patients developed TE spontaneously. A second TE event within primarily healthy siblings occurred in three of 313 families and a third event among siblings was observed in one family. In an unselected cohort of paediatric patients with symptomatic TE, the prevalence of ATD adjusted for family status was 5.1%. Given its clinical implication for patients and family members, thrombophilia testing should be performed and the benefit of medical or educational interventions should be evaluated in this high risk population.

Resumen

A descriptive type of cross-sectional study was done to measure diameters of splenic, superior mesenteric and portal veins with their variation with respiration in patients with portal hypertension. Trans-abdominal ultrasonography was used for the purpose among purposively selected 59 patients with chronic liver disease and portal hypertension using computer sonography with multiple probes having multiple frequency depending on physical built of subjects. The diameters of selected veins were measured in the course of expiration and deep inspiration. Mean age of respondents was 53.2 years with standard deviation of 11.4 years. 44 (74.6%) subjects were male, whereas 15 (25.4%) were female. In all cases oesophageal varices were present. Portal vein was clearly visualized in all cases, while splenic vein in 53 (89.8%) cases and superior mesenteric vein in 49 (83.1%) cases. During deep inspiration, diameter of portal vein was greater than 13 mm in 31 (52.5%), while ?13 mm in 28 (47.5%) of portal hypertensive cases. Of 31, lack variation in diameter during respiration was observed in 29 (93.6%) cases. Size of liver (length in mid-clavicular line) in 18 (30.5%) cases were between 96 to 115 mm, while in 19 (32.2%) cases it was within 116 to 135 mm and in 22 (37.3%) cases it was between 136 to 160 mm. In 36 (61.0%) cases surface of liver was irregular, while in 51 (86.4%) cases parenchymal echotexture of liver was coarse. Size of spleen was enlarged in 44 (74.6%) cases, and ascites was present in 47 (79.7%) cases. Diameter variation with breathing of splenic and superior mesenteric veins observed only in 5 (8.5%) patients. Lack of diameter variation of portal, splenic and superior mesenteric veins with respiration in ultrasonography is an indicator of portal hypertension.Mediscope Vol. 2, No. 1: 2015, Pages 27-31

Resumen

Cardiovascular diseases occupy a central place in the structure of morbidity and mortality in various population groups and in most cases occur with a heart rhythm disorder. One of the most common types of arrhythmia is atrial fibrillation, the morphological substrate for the development of which is the left atrium and the region of the pulmonary veins. In connection with the introduction of modern imaging systems into the practice of cardiac surgery, which enable a detailed study of the anatomy of the heart and its separate chambers, there is a need to study the features of the variant anatomy of the pulmonary veins of the human left atrium in the aspect of modern interventional cardiac surgery, which will make it possible to secure and accelerate surgical interventions performed in this area. The purpose of the study was the revealing of variant anatomy of the pulmonary veins using multislice computed tomography, depending on body type and gender. Heart tomograms of 70 patients were analyzed (8 of the 1st period of adulthood, 23 of the 2nd period of adulthood, 37 of the elderly, 2 of the senile age). Among them were 47 men - 67.1% and 23 women - 32.9%. As a result of the analysis of the obtained data, four variants of the confluence of the pulmonary veins into the left atrium were identified. Among all observations, a typical variant of the confluence of the pulmonary veins into the left atrium occurs in 78.6% of cases, in 85.7% of cases - in persons of the pyknic type, in 85.0% of cases - in the examined asthenic type and in 69.0% of cases - in representatives of the normosthenic body type. Less common are the common pulmonary vein collector on the left (12.9%), as well as the accessory pulmonary vein on the right (7.1%). An extremely rare anatomical variant was the common pulmonary vein collector on both sides (1.4%). Thus, the anatomy of the distal pulmonary veins is characterized by significant variability, there is a slight relationship with gender and body type. An in-depth study of the anatomy of the pulmonary veins remains relevant for the effective implementation of surgical interventions in this anatomical zone.

Resumen

Central venous catheters (CVCs) provide easy, immediate and rapid vascular access (VA) for hemodialysis (HD) in patients with acute renal failure (ARF), and in an increasing number of patients with end-stage renal disease (ESRD) as well. For this purpose, the vessels mainly used are the cephalic, jugular, subclavian and femoral veins. In some patients, vascular catheter insertion via these routes can become impossible. We report two hopeless cases, in which the external iliac veins (EIVs) were used as a temporary VA insertion site as a last resort.

Resumen

OBJECTIVEThe best management of veins encountered during the neurosurgical approach is still a matter of debate. Even if venous sacrifice were to lead to devastating consequences, under certain circumstances, it might prove to be desirable, enlarging the surgical field or increasing the extent of resection in tumor surgery. In this study, the authors present a large series of patients with vascular or oncological entities, in which they used indocyanine green videoangiography (ICG-VA) with FLOW 800 analysis to study the patient-specific venous flow characteristics and the management workflow in cases in which a venous sacrifice was necessary.METHODSBetween May 2011 and December 2017, 1972 patients were admitted to the authors’ division for tumor and/or neurovascular surgery. They retrospectively reviewed all cases in which ICG-VA and FLOW 800 were used intraoperatively with a specific target in the venous angiographic phase or for the management of venous sacrifice, and whose surgical videos and FLOW 800 analysis were available.RESULTSA total of 296 ICG-VA and FLOW 800 studies were performed intraoperatively. In all cases, the venous structures were clearly identifiable and were described according to the flow direction and speed. The authors therefore defined different patterns of presentation: arterialized veins, thrombosed veins, fast-draining veins with anterograde flow, slow-draining veins with anterograde flow, and slow-draining veins with retrograde flow. In 16 cases we also performed a temporary clipping test to predict the effect of the venous sacrifice by the identification of potential collateral circulation.CONCLUSIONSICG-VA and FLOW 800 analysis can provide complete and real-time intraoperative information regarding patient-specific venous drainage pattern and can guide the decision-making process regarding venous sacrifice, with a possible impact on reduction of surgical complications.

Resumen

The authors studied 61 patients undergoing effective embolization for cerebral arteriovenous malformations (AVMs) and analyzed the hemodynamic changes in their drainage systems following embolization. The changes were classified into following 5 types: type A, disappearance of all the draining veins; type B, disappearance of a part of the cortical veins; type C, disappearance of a part of the deep-seated veins; type D, combined type B and C patterns; type E, disappearance of reflux into normal cortical veins. Each case was evaluated on the basis of these criteria from comparing pre- and post-embolization angiograms. The delay and reduction of shunt were observed in all cases. Forty-nine of them showed obvious hemodynamic changes in the draining systems including type A change in 9, type B in 19, C in 5, D in 3 and E in 13 cases, respectively. Two cases showed a spontaneous shift in the dominance of the main drainers. Thirteen of 15 cases showing successful results in subsequent radiosurgery exhibited various changes in draining pattern. Changes in drainage systems may be affected by the compartmentalization of the nidus, reduction in shunt flow, and spontaneous or progressive thromboses. These can be promoted by embolization and may be regarded as one of the indicators of successful pretreatment for radiosurgery.

Resumen

Purpose to provide a road map for converting varicose veins service to endovenous ablation and assess its process and outcome on patients with varicose veins. Patients and methods Retrospective assessment of prospectively recorded data for converting vein unit which exclusively did open varicose veins surgery (OS) (39 patients from September 2019 to February 2020) to endovenous radiofrequency ablation (ERFA) service (44 patients from March 2020 to January 2021). Results There was no statistical difference in theatre time between both interventions despite dealing with more complex cases in the ERFA group with more truncal veins (χ2 =11.950*, P<0.001*) and a higher number of stab avulsions (V number) (χ2 =217.889, P<0.001*). On the other hand, the overall cost was significantly lower in open group compared to ERFA (Mean±SD 1261±386 US$ and 1519.2±392 US$ respectively, P<0.001*. This statistical difference was reduced to P=0.041 when subgroup analysis only included cases with higher number of avulsions. In multivariate analysis, cost was associated with surgical duration and using ERFA however, less complications were recorded in ERFA group (χ2=4.419* P=0.036*) and recovery time was significantly longer in open group (8.90±2.44) than in ERFA group (6.0±1.06), P<0.001* Conclusion Converting varicose veins service to a modern ERFA is safe and effective when properly planned. ERFA is associated with shorter recovery and less theatre time and complications despite higher cost which becomes more cost-effective in cases with more truncal veins and avulsion sites.

Resumen

BACKGROUND Chronic venous disorders are an important cause of disease and disability worldwide. Varicose veins are dilated, tortuous elongated veins. Varicose veins are either primary or secondary. Most of the patients are asymptomatic. Indian populations present with complications like venous bleed, thrombophlebitis, chronic venous insufficiency leading to edema, eczema, lipodermatosclerosis, and venous ulcers. Varicose vein surgery is characterized by a high recurrence rate of 20 % to 60 % after 5 years and even higher after longer periods of observation. Recurrence may be due to several causes like inaccurate initial diagnosis, progression of disease, inadequate initial surgery, altered venous dynamics, and neovascularisation. METHODS In this cross sectional single center study, 100 patients above 18 years of of age of both genders presenting with complications of varicose veins and cases of postoperative recurrent varicose veins were included. This study was conducted in the Department of General Surgery, Sri Venkateswara Ramnarayan Ruia Government General Hospital (SVRRGGH), Tirupati, over a period of one year. RESULTS In the present study, the great saphenous vein (GSV) was involved in 85 % of cases, the short saphenous vein (SSV) in 2 %, and both long and short saphenous in 9 %. The commonest complication was edema in 88 % of the patients, followed by 43 % with eczema. Recurrent varicose veins were seen in 4 % of patients. CONCLUSIONS Complications were more common in our setting at the time of presentation. Variable anatomy of the venous system of the lower limb makes prior duplex scan assessment compulsory in the surgical management of cases. Surgical management is to be planned properly after complete evaluation and should be planned at the right time, as it is a progressing clinical entity.

Resumen

✓ Intracranial dural arteriovenous fistulas (AVFs) have been recognized as acquired lesions that can behave aggressively depending on the pattern of venous drainage. Based on the type of venous drainage, they can be classified as fistulas drained only by venous sinuses, those drained by venous sinuses with retrograde flow in arterialized leptomeningeal veins, and fistulas drained solely by arterialized leptomeningeal veins. Serious symptoms, including hemorrhage and focal deficit, are related to the presence of arterialized leptomeningeal veins. In this paper, the authors report a consecutive series treated between 1988 and 1993 of 20 cases of intracranial dural AVFs with “pure leptomeningeal drainage.” All patients underwent surgical interruption of the leptomeningeal draining veins. Based on the arterial supply, nine patients were managed by direct surgery, whereas 11 patients were prepared for surgery by means of preoperative arterial embolization. Radioanatomical cure of the fistula and good neurological recovery were achieved in 18 cases. Complete obliteration of the fistula was documented angiographically in two cases, but fatal hemorrhage occurred, probably due to partial thrombosis of the venous drainage. Based on this experience, the authors believe that surgical interruption of the draining veins is the best treatment option for intracranial dural AVFs. However, surgical results may be affected by the extension of postoperative thrombosis, which in turn may be related to the degree of preoperative venous engorgement.
