Outcomes of kidney autotransplantation technique in the treatment of different ...
Mendes,Daniel A.; Machado,Rui; Veterano,Carlos; Rocha,Henrique; Castro,João; Pinelo,Andreia; Almeida,Henrique; Almeida,RuiAbstract 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 ...
Parallel grafting technique for a complex zone 6 aortic pseudoaneurysm treatment
Mendes,Daniel Azevedo; Machado,Rui; Pereira,Carlos; Castro,João; Almeida,RuiAbstract Introduction: Endovascular reconstruction of the thoracoabdominal aorta is highly complex due to the need to preserve the main visceral branches. Optimal treatment with fenestrated and branched aneurysm aortic repair (F/B-EVAR) is usually not possible in urgent situations. Parallel grafting technique as an “off-the-shelf” solution have been described with good short and medium-term results. Case report...

Veterano,Carlos; Antunes,Inês; Veiga,Carlos; Mendes,Daniel; Rocha,Henrique; Castro,João; Pinelo,Andreia; Pinto,Pedro Sá; Almeida,RuiAbstract 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...

Antunes,Inês; Pereira,Carlos; Veterano,Carlos; Veiga,Carlos; Mendes,Daniel; Rocha,Henrique; Castro,João; Pinelo,Andreia; Almeida,RuiResumo 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 imagiológic...
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,RuiAbstract 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 f...
Redefining late renal artery revascularization - splenorenal bypass in the trea...
Mendes,Daniel A.; Machado,Rui; Castro,João; Almeida,RuiAbstract 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...
The Vascular Surgery Emergency Department in times of COVID-19 pandemic.
Rocha,Henrique; Silva,Ivone; Antunes,Inês; Veiga,Carlos; Mendes,Daniel; Veterano,Carlos; Castro,João; Pinelo,Andreia; Machado,Rui; Almeida,RuiAbstract Background: The surge of the COVID-19 pandemic in Portugal and the implemented public health measures were accompanied with a noticeable decrease in patients’ attendance to the Emergency Department (ED).

Small Saphenous Vein: The limb’s small savior.
Loureiro,Luis; Castro,João; Almeida,RuiAbstract Peripheral bypass grafting with autologous vein is the gold standard treatment of peripheral artery disease. In cases when the great saphenous vein is not available the arm veins or small saphenous veins are possible alternatives. The use of small saphenous vein as a bypass conduit is not a spread practice. We present two cases of revascularization procedures using the small saphenous vein as a conduit...

Endovascular treatment of retrograde fed bilateral iliac artery aneurysms 10 ye...
Veiga,Carlos; Rego,Duarte; Silva,Ivone; Mendes,Daniel; Veterano,Carlos; Rocha,Henrique; Castro,João; Pinelo,Andreia; Almeida,Henrique; Vaz,CarolinaAbstract Introduction: The development of aneurysms in iliac arteries excluded from high-pressure direct flow from the aorta is very uncommon. We report a case of successful treatment of bilateral metachronous iliac artery aneurysms (MIA), found 10 years after an aortobifemoral bypass, with perfusion only by retrograde flow from the common femoral arteries (CFA). Case Report: A 76-year-old man came for consulta...
