The right aberrant subclavian artery, also known as arteria lusoria, is an anatomical variation described in the literature with an incidence of < 1%. Compression related symptoms can arise from the retroesophageal space and retrotracheal course of the artery. Only a few cases are reported of ischemic symptoms derived from a stenosed or occluded right aberrant subclavian artery. We present a case of ischemic right upper limb symptoms due to an occluded right aberrant subclavian...

Treatment of aortic pathologies involving the aortic arch represents a great challenge for vascular surgeons. Endografting techniques, comparing to open surgery, are less invasive approaches. However, an adequate proximal landing zone remains a challenge and, regarding this issue, parallel graft techniques represent a viable endovascular treatment option in patients with challenging aortic arch pathology by extending the proximal landing zone while maintaining aortic side branches perfusion. Parallel graft techniques required a thorough planning and the...

Introduction: Cystic adventitial disease is a rare cause of intermittent claudication. Its presentation as acute limb ischemia is exceedingly rare. This disease is caused by the growth of multiple cysts within the adventitia. Although its etiopathogeny isn’t fully understood most evidence supports an embryonic defect during the development of non-axial arteries. Treatment includes several options: adventitial layer excision, percutaneous aspiration of the cysts and segmental arterectomy with bypass. Methods: We present a case of acute...

Introduction: Endovascular repair of aortic aneurysms is widely established. However, aorto-iliac aneurysms pose a challenge, specifically regarding distal sealing. A frequent approach is extending the iliac limb to the external iliac artery (EIA) with occlusion of the internal iliac artery (IIA), often with varying degree of pelvic ischemia causing significant morbidity. Iliac branched devices (IBD) allow for the creation of distal landing zones in the EIA and IIA, maintaining pelvic perfusion. We performed a descriptive...

Introdução: Na dissecção crónica complicada de degeneração aneurismática, é frequente existirem fendas espontâneas entre o verdadeiro e o falso lúmen ao nível das artérias viscerais. No entanto, na sua ausência ou difícil identificação, o tratamento com recurso a f/bEVAR está limitado. Nesses casos, pode ser necessária a criação de fenestrações para permitir o acesso aos vasos viscerais. Métodos / Resultados: Apresentam-se 2 casos de procedimentos de fenestração de lâmina de disseção crónica em doentes submetidos...

Os fibromas uterinos são o tumor sólido pélvico mais frequente nas mulheres, geralmente condicionando hipomenorreia. Não costumam estar associados a trombose venosa profunda, mas, quando atingem dimensões consideráveis podem condicionar fenómenos compressivos a nível da veia cava inferior e veias pélvicas e consequentes fenómenos trombóticos. Posteriormente, as lesões obstrutivas pós-trombóticas das veias ilíacas poderão levar ao desenvolvimento de clínica e sintomas compatíveis com doença venosa crónica. Se por um lado não existe indicação para intervenção...

INTRODUCTION: In situ lesser saphenous vein (LSV) graft has been advocated in cases of lower limb revascularization where target arteries are confined to the lower leg and the greater saphenous vein (GSV) is neither available nor suitable. This often occurs in diabetic or end-stage renal diseased patients, whose occlusive disease pattern typically affects the tibioperoneal vessels, sparing the femoropopliteal segment. In situ technique offers the potential advantages of decreased surgical trauma to the vein, better...

Introduction: The development of aneurysms in iliac arteries excluded from high-pressure direct flow from the aorta is very uncommon. We report a case of successful treatment of bilateral metachronous iliac artery aneurysms (MIA), found 10 years after an aortobifemoral bypass, with perfusion only by retrograde flow from the common femoral arteries (CFA). Case Report: A 76-year-old man came for consultation after incidental finding of bilateral MIAs, 10-years after aorto- bifemoral bypass for treatment of an...

Background: Conventional risk factors do not explain completely the atherogenic process. Chronic Helicobacter pylori (HP) infection may cause arterial inflammation and has been epidemiologically linked to the occurrence of atherosclerosis. Studies about the association of HP infection with peripheral arterial disease are limited. Objective: Evaluate the presence of HP using a monoclonal antibody anti-HP in the atherosclerotic plaques of the superficial femoral artery in patients submitted to amputation above-knee. Material and methods: We searched for...

Methods and materials: Retrospective study in order to assess the quality of life of patients with PH undergoing ETS, from 1 of January 2009 to 31 of December 2014. The data was collected from the medical registries of each patient and from a clinical interview with the application of the quality of life...

O aneurisma da veia ázigos é uma entidade clínica rara, descrita num número reduzido de case reports na literatura. Neste artigo, descreve-se o caso de um aneurisma da veia ázigos, diagnosticado acidentalmente numa angio-tomografia computorizada (AngioTC) durante a investigação clínica de um quadro de hemoptises, numa doente do sexo feminino de 82 anos hipocoagulada com varfarina. Foi diagnosticada uma traqueobronquite e repetiu-se AngioTC após resolução do quadro agudo, que revelou trombose completa do aneurisma. Decidiu-se...

Although the femoral antegrade access is the ideal approach for endovascular treatment of infra-inguinal occlusive disease, there are situations where this is not feasible. And how to solve the problem of an approach when, after a retrograde femoral puncture for a diagnostic angiography, we intend to treat endovascularly the infra-inguinal sector of the punctured side? To apply an inversion technique of a retrograde access is a viable alternative. We present the case of a patient...

Endovascular treatment of juxtarenal aortic aneurysms is a complex challenge to the vascular surgeon. We present a case of an 83 year old man with a large juxtarenal aneurysm treated with an endovascular approach with chimneys to the left renal artery and superior mesenteric artery. Fenestrated aortic endovascular repair has been considered the preferred endovascular approach in juxtarenal aneurysms, however when the risk of rupture is considered high to wait for a manufactured device and/or...

Introdução: A degeneração aneurismática das artérias ilíacas está presente em 11 a 43% dos aneurismas da aorta abdominal. O recurso a endopróteses ilíacas bifurcadas (IBDs) permite preservar a artéria ilíaca interna (AII) obviando as significativas complicações inerentes à sua oclusão. Material e Métodos: Análise retrospectiva da série consecutiva de doentes selecionados para tratamento endovascular através do uso de IBDs numa instituição terciária no período de Setembro 2010 a Abril 2016. Resultados: Foram tratados com IBDs...

Abstract Introduction: The presence of symptomatic atherosclerotic stenosis of the innominate artery is an uncommon condition. The authors report the use of kissing stent technique in right subclavian and common carotid arteries with covered stents and cerebral protection by direct clamping of common carotid artery, as a hybrid endovascular alternative to treat symptomatic stenosis of the innominate artery. Case Report: A 75-year-old male was admitted to Vascular Surgery Department with repeated transient ischemic attacks (TIA’s)...

Introduction: Type B aortic intramural hematoma (B-IMH) has a complex and variable natural history: it can remain stable and resolve spontaneously or progress to dissection, aneurysm, ulcer or even rupture. The possibility of disease progression, frequently with mild or no symptomatology, poses a significant treatment dilemma. Clinical Case: We report a case of a 60 year-old-female diagnosed with an acute B-IMH, initially treated medically. However, 1-month control CTA revealed disease progression (increased B-IMH thickness and...

Introduction: Between 14–20% of patients with critical lower-limb ischemia (CLI) are not candidates for revascularization due to extensive occlusions in crural/pedal vessels. Frequently these patients are young and functionally active. In these cases, the concept of shunting blood through veins to get this reversed flow to reach the nutritive tissue capillary bed becomes attractive. Our aim is to report our very recent experience in venous arterialization. Material/Methods: We retrospectively reviewed the cases of venous arterialization...

A laceração traumática da aorta é uma lesão de elevada mortalidade pré-hospitalar e intra-hospitalar. A sobrevivência a este tipo de lesões é rara e escasseiam dados sobre o prognóstico a longo-prazo destes doentes. Descrevemos um caso clínico de reparação primária de laceração da aorta torácica que se apresentou 29 anos após a repa- ração inicial com aneurisma da aorta torácica na mesma topografia. Foi submetido a reparação endovascular do aneurisma. Discutem-se as técnicas de reparação...

Introduction: Above-knee stump ischemia is a serious condition. If left untreated usually courses with progression to irreversible ischemia. Without treatment the path from here usually leads to hip disarticulation and death. Our aim is to present our most recent experience in stump revascularization. Material/Methods: We retrospectively reviewed all patients with above-knee stump ischemia treated in our institution between July 2018 to March 2019. Results: We present four clinical cases treated in our institution in the...

Introduction: A number of guidelines for the management of carotid disease are available to help clinicians in therapeutic decision and provide useful guidance for the best care of the patients. They stated that carotid endarterectomy (CEA) has some benefit in symptomatic patients with carotid stenosis of 50-69% and is highly beneficial in stenosis of 70-99%, with mortality/ stroke rate less than 6%. The maximum benefit is observed when surgery is performed within two weeks after...

Introduction: The degeneration of arterial aneurysms is a common manifestation of atherosclerosis, a process that involves the arterial vasculature, occurring in several arterial territories. With the increase of life expectancy, the number of patients with arterial aneurysms has increased, since its prevalence raises with age. Society of Vascular Surgery classifies arterial aneurysms according to their etiology. The most common form is the degenerative aneurysm, which can result from arterial wall degeneration due to several factors...
