Endovascular Repair of Contained Abdominal Aortic Aneurysm Rupture With Aortocaval Fistula Presenting With High-Output Heart Failure

Aortocava fistula is a rare condition ranging from 0.22% to 6% of all ruptured aortic aneurysms. Recognition and diagnosis of this entity can often be difficult and requires heightened clinical suspicion to ensure that prompt surgical management leads to a favorable outcome. We herein describe the diagnosis and the technical points of successful endovascular management of aortocaval fistula in the setting of a ruptured abdominal aortic aneurysm.
