Common iliac aneurysm rupture after previous aortic aneurysm resection.

INTRODUCTION Ruptured common iliac aneurysms present with diagnostic and therapeutic challenges. This case describes the successful outcome in a patient with complex vascular surgical history. CASE PRESENTATION An elderly patient presented with abdominal pain confirmed by CT as leaking iliac aneurysm. He had previously undergone an aorto-bifemoral bypass graft for ruptured abdominal aortic aneurysm. The iliac aneurysm was treated by simple ligation of the external iliac artery. DISCUSSION Aorto-bifemoral bypass graft may be required for aortic aneurysm repair in severe iliac calicification. Iliac artery fed by retrograde blood flow from the aorto-bifemoral bypass graft contributed to aneurysm development here.
