Open Surgery and Endovascular Techniques in Treatment of Acute Abdominal Arteriovenous Fistulas

Abstract

Acute abdominal arteriovenous fistulas in the setting of ruptured abdominal aortic aneurysms are a life-threatening condition; thus, a prompt diagnosis is required for proper treatment. Open, endovascular, and hybrid repair have been proposed for their management, with pros and cons for each method. In particular, the evolution of endoluminal techniques guarantees an increasing feasibility of these procedures, and a significant reduction in morbidity and mortality rates was usually associated with open surgery. Nevertheless, some concerns still remain regarding the midterm and long-term follow-up. The aim of this article was to review and compare the reported clinical and technical results of conventional open surgery and endoluminal techniques in this scenario and to report the case of an acute aorto-iliac fistula due to a ruptured common iliac artery aneurysm into the iliac vein that was managed by endovascular repair at our institution.
