Covered versus uncovered stents for malignant superior vena cava syndrome: a sy...

Abstract Introduction: In recent years, endovascular stenting has emerged as a promising palliative therapeutic modality for carefully selected patients with Superior Vena Cava Syndrome (SVCS) secondary to intra-thoracic malignancies. However, a lack of data hinders procedure standardization, particularly regarding the dichotomy of covered versus uncovered stents. This study aims to compare the outcomes of mali...

Complex solutions to minimise vascular access complications during iliac branch...

Abstract Introduction: Secondary implantation of iliac branch devices (IBDs) after endovascular aortic repair (EVAR) for type Ib endoleak poses unique technical challenges due to altered aortoiliac anatomy and prior femoral access. Selecting an optimal access strategy is critical to minimize complications and ensure procedural success. This review summarizes contemporary transfemoral and upper extremity access ...

Total endovascular arch repair: should it be the first-line option in the elect...

Abstract Background: Although the traditional standard of care for aortic arch aneurysms is open surgical arch replacement, this approach usually requires sternotomy, cardiopulmonary bypass and hypothermic arrest. Even among the subset of patients fit for open surgery, it is associated with a pooled mortality and stroke rate of around 5%. Nowadays, a multidisciplinary team of vascular and cardiac surgeons is ma...

High-dependency unit care after carotid endarterectomy for asymptomatic stenosis

Abstract Introduction: Asymptomatic patients benefit from 3 to 6 hours of neurological and invasive blood pressure (BP) monitoring following carotid endarterectomy (CEA). Only a minority of patients will benefit from a prolonged stay in a high-dependency unit (HDU). The aim of this study was to externally validate previously described predictive variables of postoperative need for prolonged HDU stay. Methods: T...

Splenic artery aneurysms - a systematic review of the literature

Abstract Introduction: Splenic artery aneurysms (SAA) are the most frequent (50 to 75%) abdominal visceral arterial aneurysms. In autopsy studies, the overall incidence is 0.01%, increasing to 10.4% with age. Due to their rarity, there is a lack of data, so we aimed to perform a systematic review of available SAA data.. Methods: A systematic review was performed according to the PRISMA guidelines. A literature ...

State of the art on restenosis after carotid artery stenting: incidence, risk f...

Abstract Introduction: Carotid revascularization is a well-established technique for preventing stroke in patients with significant symptomatic or asymptomatic carotid artery stenosis. Carotid artery stenting (CAS) has become an alternative to carotid endarterectomy (CEA), especially in high-risk surgical patients. However, restenosis after CAS is a potentially severe complication that can impact the medium and...

Endovascular treatment versus open surgery for iliac artery aneurysms: a system...

Abstract Introduction: Due to their relative rarity, the natural history of iliac artery aneurysms and treatment outcomes are poorly understood. However, IAA treatment has evolved, and nowadays, there are a variety of open surgery, endovascular therapy, and hybrid options. This study aimed to compare the outcomes of endovascular treatment versus open surgery for patients with iliac artery aneurysms. Methods: A ...

Gastrointestinal Metastatic Melanoma: The Key for Diagnosis

Alergia às proteínas do leite de vaca com manifestações gastrointestinais

A alergia às proteínas do leite de vaca (APLV) constituiu a alergia alimentar mais frequente em crianças com idade inferior a três anos, podendo as suas manifestações gastrointestinais ocorrer em qualquer idade. Na suspeita clínica de APLV baseada na anamnese e exame físico, deve instituir-se dieta de eliminação durante um período variável consoante o quadro clínico, seguida de uma prova de provocação oral (PPO...
