Ilio-Iliac Arteriovenous Fistula Secondary to a Ruptured Right Common Iliac Artery Aneurysm and Anomalous Anatomy of Inferior Vena Cava Resulting in an Arteriovenous Shunt Formation with Right-sided Cardiac Failure: A Case Report

Yuki Shirai, et al.

INTRODUCTION: An ilio-iliac arteriovenous fistula (IIAVF) secondary to the rupture of a common iliac artery aneurysm (CIAA) is rare. Sudden arteriovenous shunting and subsequent fistula enlargement can result in acute cardiac failure. Immediate diagnosis and treatment are required; however, the clinical symptoms differ from those of a free wall rupture of an aortic aneurysm, making a quick diagnosis difficult.
