The stent graft barnacle - edge hyperplasia following femoral artery implant in a young female

Tiago Ribeiro & Frederico Bastos Goncalves
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 *)....

Endovascular approach as first-line therapy for congenital arteriovenous malformations – a case series

Andreia Pinelo, Luís Loureiro, Paulo Almeida, Daniel Mendes, Carlos Veterano, João Castro, Henrique Rocha & Rui Almeida
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...

Aortoiliac occlusive disease: open or endo? – a narrative review

Ana Carolina Semião, Clara Nogueira, Andreia Coelho, João Peixoto, Luís Fernandes, Marta Machado, Francisco Basílio & Alexandra Canedo
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....

Nellix stent graft explant: a great challenge for late open conversion of failed endovascular aortic repair

Pedro Pinto Sousa, Inês Antunes, Sandrina Braga, João Correia Simões, Celso Carrilho & Amílcar Mesquita
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...

Light induced amaurosis: a rare symptom of carotid stenosis

Henrique Andrade De Almeida, Sérgio Teixeira, Luís Loureiro, Carlos Veiga, Daniel Mendes, Carlos Veterano, Henrique Guedes Da Rocha, João Diogo Castro, Andreia Pinelo & Rui De Almeida
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....

Internal carotid artery trauma due to elongated styloid process – a review of case reports

Celso M. D. Nunes, Juliana Sousa, Joana Silva, Vânia Constâncio, Eduardo Silva, Leonor Baldaia & Miguel Silva
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...

Redefining late renal artery revascularization – splenorenal bypass in the treatment of acute renal artery occlusion

Daniel A. Mendes, Rui Machado, João Castro & Rui Almeida
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...

Predictive factors of venous stenting failure: a systematic review

Ana Carolina Semião, Clara Nogueira, Andreia Coelho, João Peixoto, Luís Fernandes, Marta Machado, Francisco Basílio & Alexandra Canedo
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...

Clinical outcomes after vena cava thrombectomy for renal cell carcinoma with venous extension – institutional experience

Fábio Pais, José Aragão De Morais, Ana Quintas, Rita Soares Ferreira, Joana Catarino, Ricardo Correia, Rita Bento, Rita Garcia, Frederico Bastos Gonçalves & Maria Emília Ferreira
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...

Tratamento de pseudoaneurismas femorais com tumescência: uma revisão sistemática da literatura

Adriana Figueiredo, Frederico Bastos Gonçalves, Nelson Camacho, Joana Cardoso, Tiago Ribeiro, Helena Fidalgo & Maria Emília Ferreira
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...
