INTRODUCTION The femoropopliteal biomechanical characteristics make the endovascular treatment of complex lesions particularly challenging. Despite several studies reporting longer patency of femoropopliteal stenting when compared to balloon angioplasty, long-term outcomes are still marginal due to the high rate of restenosis, stent fracture, and thrombosis. This study aims to review the current literature on t...
INTRODUCTION: Chimney EVAR (ChEVAR) for the treatment of complex abdominal aortic aneurysm (AAA) has been largely relegated for when fenestrated endografts are unavailable, especially due to durability concerns. However, the off-the-shelf nature of ChEVAR makes it a good option for emergent AAA repair. We report our institutional experience in ChEVAR in an urgent setting.METHODS: ChEVAR procedures were collecte...
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 su...
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 surgic...
Peripheral arterial disease (PAD), abdominal aortic aneurysm (AAA) and chronic mesenteric ischaemia (CMI) are vascular diseases uncommonly observed in the same patient, especially when treatment is required. This case report illustrates a patient requiring mesenteric revascularization due to CMI. A long flush occlusion of the superior mesenteric artery (SMA) precluded endovascular revascularization. Therefore, ...
INTRODUCTION: Kidney autotransplantation (KAT) is a versatile surgical technique used to treat multiple diseases affecting the kidney. This procedure allows the reconstruction of the renal artery or vein with optimal surgical exposure reducing warm ischemia time compared to open direct repair. Although infrequently reported nowadays and despite the growing use of endovascular treatments, KAT still has a place i...
Introduction: Renal artery aneurysms are rare clinical entities whose treatment criteria are not fully established. Endovascular treatment has gained acceptance in the case of renal artery trunk aneurysms. However, in the case of aneurysms of the renal artery branches, such procedures are often impossible due to high morbidity, so the question remains about the best treatment modality. We present a clinical cas...
INTRODUÇÃO: O fenómeno de nutcracker refere-se à compressão da veia renal esquerda (VRE), habitualmente entre a aorta e a artéria mesentérica superior. Quando sintomático, designa-se síndrome de nutcracker. Os sintomas/sinais estão relacionados com o desenvolvimento de hipertensão venosa renal e o diagnostico depende da conjugação da clínica e alterações laboratoriais na presença de critérios ...
INTRODUCTION: Ectopic kidneys with concomitant aortoiliac aneurysmal disease have been previously reported in the literature, however its exact prevalence is unknown. The objective of this review is to summarize current knowledge on the treatment this special group of patients. METHODS: A non-systematic literature research was performed on the treatment of aortoiliac aneurysmal disease in patients with ectopic ...
