Incorporation of internal iliac arteries as target vessels during physician-modified fenestrated branched endovascular repair of pararenal abdominal aortic aneurysm with concomitant bilateral short common iliac artery aneurysms

Abstract

This report describes an alternative endovascular approach to iliac branch devices for treatment of an abdominal aortic aneurysm with concomitant bilateral short common iliac aneurysms. The short distance between the renal arteries and internal iliac artery origins made the addition of distal iliac branch devices to the proximal fenestrated stent graft challenging. We elected to perform physician-modified fenestrated branched endovascular repair, using four fenestrations for the visceral and renal arteries and an additional two directional branches for the bilateral internal iliac arteries. The patient recovered uneventfully, and the 24-month follow-up imaging shows successful aneurysm exclusion with patent internal iliac artery branches.
