Resumo A fístula arteriovenosa (FAV) é uma sequela incomum de rotura espontânea de aneurisma arterial dentro do sistema venoso adjacente. Descrevemos, em um paciente de 74 anos, o tratamento endovascular de FAV ilíaca à direita por aneurisma de artéria ilíaca comum (AIC) roto associado a aneurisma de AIC distal à esquerda, em cuja cirurgia foram preservadas as artérias lombares e mesentérica inferior por necessidade de excluir simultaneamente as artérias hipogástricas. Foram demonstrados os fenômenos na dinâmica do balanço hídrico ocorridos em decorrência da interrupção da FAV. A evolução do paciente foi benigna, com normalização das graves alterações hemodinâmicas que apresentava e com desaparecimento dos sintomas respiratórios atribuídos à hipertensão arterial pulmonar.

Abstract An arteriovenous fistula (AVF) is an uncommon sequela of spontaneous arterial aneurysm rupture into the adjacent venous system. We describe the case of a 74-year-old patient who underwent endovascular treatment of a right iliac AVF caused by a ruptured common iliac artery (CIA) aneurysm and a distal left CIA aneurysm. Surgery preserved the lumbar and inferior mesenteric arteries because of the need to simultaneously exclude the hypogastric arteries. Dynamic fluid balance phenomena provoked by closure of the AVF are described. The patient had a benign postoperative course with normalization of the severe hemodynamic changes presented prior to the intervention and resolution of respiratory symptoms attributed to pulmonary arterial hypertension.

Our objective is to report a case of a patient with a descending thoracic aortic aneurysm and chronic aortic dissection, who was submitted to an endovascular treatment. A 68-year-old male with coronary artery disease and hypertension, with no history of trauma, diabetes or smoking. He had myocardial infarction ten years ago. Under general anesthesia, the left femoral artery was surgically exposed and the left braquial artery was catheterized with a "pigtail" catheter, under Seldinger technique. The proximal 46mm/Æ and distal 34mm/Æ stent-graft was placed just distal to the origen of the left subclavian artery. Control arteriography showed that the lesion was completely excluded. The patient was discharged seven days after the surgery, when a computed tomographic control, was performed showing a sustained aneurysm exclusion and a satisfactory endovascular position.
