Aortocaval Fistula Secondary to a Contained Ruptured Abdominal Aortic Aneurysm

Abstract

Aortocaval fistula (ACF) is a rare complication of abdominal aortic aneurysm (AAA) involving fewer than 1% of all AAAs. ACF through a contained ruptured aortic aneurysm is an extremely uncommon complication following ruptured abdominal aortic aneurysm. ACF may cause severe hemodynamic disturbance due to a left-to-right shunt. We report here a case of ACF secondary to a contained ruptured abdominal aortic aneurysm, in a 65-year-old woman, which to our knowledge has not been reported in the literature before. Its diagnosis and treatment are presented in this article.
