title: Short- and midterm results of iliac artery stenting for flush occlusion with the assistance of an occlusive contralateral iliac artery balloon.
abstract: BACKGROUND
  Endovascular treatment of flush iliac artery occlusion remains a challenge and is most often performed using open surgery. We report the outcomes of 10 cases that were successfully recanalized endovascularly with the assistance of a contralateral occlusive balloon.
  
  
  METHODS
  A retrospective review of patients undergoing iliac artery stenting was performed at a single institution. Technical success, short- and midterm patency, and 30-day complications are reported.
  
  
  RESULTS
  Ten patients were identified. Technical success was 100% when a brachial approach was used. Retrograde recanalization was attempted in 3 cases. Reentry into the aorta could not be achieved in 1 case. The aorta was entered above the inferior mesenteric artery (IMA) in the other 2 cases, and the decision was made to attempt a brachial approach to avoid stenting above the IMA. There were no dissections or perforations. Two patients developed brachial access complications, but only 1 required operative repair for a pseudoaneurysm. Nine patients (90%) remained patent at a mean follow-up of 14.6 months (range 9-24 months). One patient presented 9 months later with iliac artery stent and lower extremity bypass thromboses, which resulted in an amputation. There were no deaths in this series.
  
  
  CONCLUSIONS
  Iliac stenting for flush iliac artery occlusion can be achieved with this technique with encouraging short- and midterm results and minimal morbidity.
