title: Open Surgical Repair Can Be One Option for the Treatment of Persistent Type II Endoleak after EVAR.
abstract: OBJECTIVE
  Endovascular abdominal aortic aneurysm repair (EVAR) is an increasingly used method of repairing abdominal aortic aneurysm (AAA). However, the treatment of persistent type II endoleak is still a controversial issue. Five cases are reported here in which we performed open surgical repair of growing aneurysm due to persistent type II endoleak.
  
  
  METHODS
  Totally 128 EVAR cases were retrospectively reviewed, which were operated in our hospital from April 2008 to October 2013. These cases were followed by periodical contrast-enhanced computed tomography (CT) after EVAR. When persistent type II endoleak caused aneurysm sac growth, we performed surgical repair method for the first line treatment. In the operation, we incised the aneurysm sac by abdominal small median incision approach and sutured lumber arteries from inside of aneurysm sac and tied inferior mesenteric artery (IMA) in addition to aneurysmorrhaphy. Contrast-enhanced CT scanning was performed in a week after open repair for the confirmation of complete treatment.
  
  
  RESULTS
  Five of 128 cases (3.9%) were needed to be surgically repaired because of aneurysm sac growth (>5 mm), including two ruptured AAA cases. All patients recovered uneventfully. Contrast-enhanced CT scanning performed a week after these operations showed no endoleak and intact stent grafts and reduction of the aneurysm size.
  
  
  CONCLUSIONS
  We believe open surgical repair method of persistent type II endoleak with aneurysm expansion is secure method, and can be one of the preferable options for this life threatening complication after EVAR.
