Left Common Iliac Artery Aneurysm Rupture to an Iliac Vein with a Venous Anomaly: A Case Report.

Abstract

Ruptured iliac artery aneurysms are serious conditions with high mortality, occasionally perforating into the venous system. A 73-year-old male presented with left leg edema and a pulsatile left lower abdominal mass. Computed tomography revealed a ruptured left common iliac artery aneurysm with perforation into the left common iliac vein. Additionally, bilateral internal iliac veins were noted to form an anomalous common trunk draining into the left common iliac vein. Treatment involved internal iliac vein balloon occlusion under fluoroscopy followed by open surgery for artificial graft replacement and fistula repair. The patient was discharged on the 8th postoperative day.
