Endovascular exclusion of symptomatic bilateral common iliac artery aneurysms with preservation of an aneurysmal internal iliac artery via a reverse-U stent-graft

Abstract

Purpose: To report a technique to maintain flow to an aneurysmal internal iliac artery (NA) when treating bilateral common iliac artery (CIA) aneurysms with an aortomonoiliac stent-graft and femorofemoral bypass. Technique: First, an external iliac artery (EIA) to IIA endograft is placed distal to the IIA aneurysm then the contralateral IIA is embolized with coils. An aortomonoiliacstent-graft extending to the contralateral EIA is placed, and the procedure is completed with a femorofemoral bypass. Conclusion: Endovascular treatment of bilateral CIA aneurysms and combined with a unilateral IIA aneurysm is a technically demanding procedure. An endovascular repair with retrograde (reverse-U stent-graft) hypogastric artery preservation can be considered a first choice until the use of branched iliac stent-grafts becomes more widespread. © 2006 by the International Society of Endovascular Specialists.
