Correção cirúrgica de aneurismas saculares de fístula arteriovenosa para hemodiálise utilizando a técnica de aneurismorrafia

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.
