Resumo

Uma das complicações mais frequentes da fístula arteriovenosa (FAV) para hemodiálise é o desenvolvimento de um aneurisma. A formação de aneurismas geralmente decorre de um enfraquecimento da parede venosa devido às repetidas punções, e sua rotura causa hemorragia intensa que pode levar à morte. Descrevemos o caso de uma paciente com dois aneurismas saculares de FAV, tratados através de aneurismorrafia, detalhando a técnica cirúrgica utilizada e a evolução pós-operatória. A técnica de rafia simples da parede constitui uma boa alternativa no reparo da parede da FAV quando o aneurisma é de curta extensão, evitando a colocação de um material protético e a confecção de duas anastomoses.

Abstract

One of the most common complications of arteriovenous fistulas (AVF) is aneurysm formation due to weakening of the venous wall after repeated punctures. Its rupture causes severe bleeding that can lead to death. We report the case of a patient with two AVF saccular aneurysms treated by aneurysmorrhaphy. The technique and the postoperative follow-up are presented in detail. Aneurysmorrhaphy is a good option to repair the AVF wall when the aneurysmal segment is short, thus avoiding the placement of prosthetic grafts and the performance of two anastomoses.
