title: Endovascular exclusion of symptomatic bilateral common lliac artery anueurysms with preservation of an aneurysmal internal lliac artery via a reverse-U stent-graft.
abstract: OBJECTIVE
  To report a technique to maintain flow to an aneurysmal internal iliac artery (IIA) when treating bilateral common iliac artery (CIA) aneurysms with an aortomonoiliac stent-graft and femorofemoral bypass.
  
  
  METHODS
  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 aortomonoiliac stent-graft extending to the contralateral EIA is placed, and the procedure is completed with a femorofemoral bypass.
  
  
  CONCLUSIONS
  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.
