Endograft Exclusion of Residual Common Iliac Artery Aneurysms

Abstract

Purpose: To describe an endovascular approach for residual common iliac artery (CIA) aneurysm. Methods and Results: A residual CIA was discovered in a 73-year-old man during routine examination following straight interposition graft placement for a ruptured abdominal aortic aneurysm (AAA). An aortobifemoral bypass was performed with ligation of both aneurysmal iliac arteries. A year later, aneurysms of both CIA stumps were found. On each side, a Hemobahn stent-graft was percutaneously positioned from the external to the internal iliac artery via the superficial femoral artery. Control angiography at 2 months and spiral computed tomographic angiography at 6 and 18 months confirmed exclusion of the aneurysms and patency of the endoprostheses. Conclusions: Successful endovascular treatment of residual CIA aneurysm is possible with flexible stent-grafts.
