The challenging management of acute mesenteric ischemia - too frail or too late?
Pinelo, Andreia; Loureiro, Luís; Mendes, Daniel; Rocha, Henrique; Almeida, Henrique; Queirós, Miguel; Cabral, João; Machado, RuiINTRODUCTION: acute mesenteric ischemia (AMI) presents a life-threatening emergency, requiring a high degree of suspicion for timely diagnosis. Despite advancements in the management of these patients, in-hospital mortality rates remain high. This study aims to assess the outcomes and prognostic factors in patients with AMI. METHODS: A retrospective single-center analysis of all patients undergoing emergent sur...
Extra-cranial internal carotid aneurysm repair – the importance of technical de...
Pinelo, Andreia; Mendes, Daniel; Rego, Duarte; Loureiro, Luís; Machado, RuiBACKGROUND: Extracranial internal carotid aneurysms are extremely rare and usually diagnosed as incidental findings although thromboembolic events or rupture can occur. Historically treated by open surgery, endovascular repair is emerging as an alternative. We present our center’s experience with both approaches. CASE REPORTS: Four internal carotid aneurysm cases are presented: Case 1 – 60-year-old male present...
Mid and long-term results of the Supera® stent in femoropopliteal obstructive d...
Pinelo, Andreia; Loureiro, Luís; Veterano, Carlos; Rocha, Henrique; Castro, João; Machado, RuiINTRODUCTION 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...
ChEVAR technique for emergent aneurysm repair - a retrospective case series
Veterano, Carlos; Sá Pinto, Pedro; Pereira, Carlos; Martins, Joana; A. Mendes, Daniel; Rocha, Henrique; Pinelo, Andreia; Machado, RuiINTRODUCTION: 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...
Light induced amaurosis: a rare symptom of carotid stenosis
Andrade de Almeida, Henrique; Teixeira, Sérgio; Loureiro, Luís; Veiga, Carlos; Mendes, Daniel; Veterano, Carlos; Guedes da Rocha, HenriqueINTRODUCTION: 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...
Endovascular approach as first-line therapy for congenital arteriovenous malfor...
Pinelo, Andreia; Loureiro, Luís; Almeida, Paulo; Mendes, Daniel; Veterano, Carlos; Castro, João; Rocha, Henrique; Almeida, RuiINTRODUCTION: 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...
Outcomes of kidney autotransplantation technique in the treatment of different ...
A. Mendes, Daniel; Machado, Rui; Veterano, Carlos; Rocha, Henrique; Castro, João; Pinelo, Andreia; Almeida, Henrique; Almeida, RuiINTRODUCTION: 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...
BILATERAL KIDNEY AUTOTRANSPLANTATION AS A SOLUTION FOR MULTIPLE ANEURYSMS OF TH...
Mendes, Daniel Azevedo; Machado, Rui; Veiga, Carlos; Veterano, Carlos; Rocha, Henrique; Castro, João; Pinelo, Andreia; Almeida, Henrique; Alemida, RuiIntroduction: 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...
Transposição de veia ovárica como um tratamento cirúrgico menos invasivo para a...
Antunes, Inês; Pereira, Carlos; Veterano, Carlos; Veiga, Carlos; Mendes, Daniel; Rocha, Henrique; Castro, João; Pinelo, Andreia; Almeida, RuiINTRODUÇÃO: 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 ...
Considerations on the treatment for aortoiliac aneurysmal disease with concomit...
Veterano, Carlos; Antunes, Inês; Veiga, Carlos; Mendes, Daniel; Rocha, Henrique; Castro, João; Pinelo, Andreia; Sá Pinto, Pedro; Almeida, RuiINTRODUCTION: 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 ...
