title: Using bilateral iliac branch devices for endovascular iliac aneurysm repair.
abstract: BACKGROUND
  The endovascular repair of bilateral iliac aneurysms using bilateral Iliac Branch Devices (IBDs) has been infrequently performed and reported.We aim to describe this technique and report on the results of our case series.
  
  
  METHODS
  Three different device designs are available. The procedural options include a totally transfemoral approach, or a combined transfemoral and brachial approach. Clinical records for patients who have had this procedure were reviewed.
  
  
  RESULTS
  The indications for the technique include bilateral common iliac artery aneurysm repair, with or without concomitant abdominal aortic aneurysm repair. Considerations include the timing of main body endovascular aortic aneurysm repair (EVAR) device introduction, the use of a proximal access site and the type of IIA stent-graft that is used. Between 2007 and 2010, six patients had bilateral IBD implantation. All patients required an EVAR main body device in addition to bilateral IBDs. Eighty-three per cent were males, mean age was 73 years. Mean follow up was 15 months. Technical success was obtained in 100% of cases. There was one branch occlusion (8.3%). There were no type I endoleaks. One patient had a type II endoleak.
  
  
  CONCLUSIONS
  Bilateral IBDs can be used safely and with excellent rates of technical success and branch patency in appropriately selected patients.
