title: Endovascular repair of bilateral common iliac artery aneurysms using GORE Excluder iliac branch endoprosthesis without aortobi-iliac stent graft conjunction: A case report.
abstract: BACKGROUND
  Bilateral common iliac artery (CIA) aneurysm (CIAA) is a rare entity. In the past decade, different endovascular approaches have been adopted for patients with several comorbidities or unfit for open repair (OR). Recently, the use of iliac branch stent graft has been proposed, resulting in satisfactory patency rates and decrease in morbidity. Currently, according to instruction for use, the iliac branch stent graft is to be used with aortobi-iliac stent graft conjunction. We describe a case of a successful endovascular repair of bilateral CIAAs using the GORE Excluder iliac branch endoprosthesis (IBEs) without aortobi-iliac stent graft conjunction.
  
  
  METHODS
  An 83-year-old man was admitted with abdominal pain and presence of pulsatile mass in the right and left iliac fossa. Computed tomographic (CT) angiography showed the presence of large bilateral CIAAs (right CIA = 66 mm; left CIA = 38 mm), without concomitant thoracic or abdominal aorta aneurysm. Moreover, CT scan demonstrated the presence of bilateral lower accessory renal artery close to the aortic bifurcation. Due to the high operative risk, the patient was scheduled for endovascular repair with bilateral IBEs, without the aortobi-iliac stent graft conjunction to avoid the renal ischemia as a consequence of renal arteries covering. The procedure was completed without complications and duplex ultrasound demonstrated the complete exclusion of both aneurysms without any type of endoleaks at 1 month of follow-up.
  
  
  CONCLUSIONS
  GORE IBEs without aortobi-iliac stent graft conjunction seem to be a feasible and effective procedure for the treatment of isolated CIAAs in patients with highly selected anatomical conditions.
