A 37-year-old female underwent an emergent implant of a covered self-expandable stent graft (8mm x 10cm Viabahn, W. L. Gore) due to acute bleeding from a femoral access following closure of a patent foramen ovale. Over the following months, intermittent claudication developed, progressively more incapacitant. Work-up revealed near-occlusion of the stent graft due to edge stenosis. Elective explant of the stent graft was performed, revealing extensive proximal and distal edge miointimal hyperplasia (marked with *)....

INTRODUCTION: Congenital vascular malformations are entities with a broad spectrum of presentations and variable prognosis. They typically present at a young age and are historically associated with extensive resection surgeries and with high morbidity. This study aims to evaluate the results of arteriovenous malformations (AVMs) embolization as a first-line approach in lesions which are not suitable for surgical resection. METHODS: A retrospective analysis of the clinical records of patients with infiltrative arteriovenous malformations who underwent...

INTRODUCTION: Aortoiliac occlusive disease (AIOD) can be treated using either open surgical revascularization (OSR) or endovascular revascularization (ER). METHODS: A Medline search was performed in order to identify articles focused on the treatment of aortoiliac occlusive disease. Additional articles of scientific interest for the purpose of this non-systematic review were included by cross-referencing. RESULTS: There are a few articles reporting direct results between both techniques based on retrospective or prospective single center or multicenter studies....

INTRODUCTION: The concept of the Nellix endoprosthesis is based on endovascular aneurysm sealing with endobags and was launched in the market for endovascular abdominal aortic aneurysm repair (EVAR). The manufacturer recently issued a hazard alert due to higher rates of endoleaks, migration and aneurysm enlargement. CASE REPORT: The authors present a clinical case of a seventy year-old man previously submitted to EVAR with a Nellix device in another country. The patient presented with an asymptomatic...

INTRODUCTION: Light induced amaurosis refers to a transient monocular or binocular vision loss triggered by bright lights. Like amaurosis fugax, light induced amaurosis is associated with carotid artery stenosis but they differ from each other in presentation and pathophysiology. It is thought to be an impairment in the regeneration of retinal visual pigments caused by the inability of carotid circulation to sustain the increased metabolic activity occurring when the retina is exposed to bright lights....

INTRODUCTION: Stylocarotid syndrome is caused by the conflict between the styloid process and the vascular structures leading to carotid artery dissection (CAD) or compression. Being headache the most common initial symptom in patients with spontaneous CAD, eagle syndrome could be one explanation for some so-called spontaneous dissections since this symptom is also common in this syndrome. METHODS: Afrer analyzing the reported cases on Pubmed and Embase databases we divided the cases in compression and CAD...

INTRODUCTION: The ischemic window of kidney parenchyma is narrow, so a rapid development of renal infarction after acute renal artery occlusion is expected. However, patients often present with nonspecific symptoms and laboratory findings, making the early diagnosis challenging and contributing to treatment delay. Irreversible kidney dysfunction seems not to depend on the total warm ischemia time alone, and other factors could play a role. CASE REPORT: A 64-year-old male with chronic kidney disease presented to...

OBJECTIVE: Venous stenting of iliocaval obstructions has become a more frequent procedure over the last two decades. In-stent stenosis and thrombosis are potential complications, causing one of the main causes of symptoms recurrence and impacting quality of life. The aim of this review is to report on the impact of venous stent patency loss, as well on risk factors and management. METHODS: A systematic review was conducted according to the recommendations of the PRISMA (Preferred...

INTRODUCTION: Renal cell carcinoma (RCC) frequently progress to involve the inferior vena cava (IVC) and even the right atrium (RA). Nephrectomy and eradication of the tumour thrombus, can extend survival and prevent symptoms of venous congestion. The authors evaluated the institutional experience of a tertiary center in the surgical management of RCC patients with tumour thrombi invading the IVC. METHODS: Retrospective analysis of a single-center consecutive serie of patients with RCC and IVC tumor thrombi...

INTRODUÇÃO: Com o crescente uso das técnicas endovasculares, seja para fins diagnósticos ou terapêuticos, o pseudoaneurisma iatrogénico da artéria femoral é uma complicação cada vez mais frequente. A par deste aumento de incidência foram surgindo alternativas à cirurgia convencional para o seu tratamento, nomeadamente soluções percutâneas e endovasculares. Em 2003 foi descrito pela primeira vez um novo método minimamente invasivo, rápido e de baixo custo: a oclusão percutânea com tumescência através da injeção peri-aneurismática eco-guiada...
