title: Endovascular repair of abdominal aortic aneurysms with aortocaval fistula.
abstract: OBJECTIVE
  To examine the risk of high-flow type II endoleak following endovascular repair of abdominal aortic aneurysm with aortocaval fistula.
  
  
  METHODS
  Case reports.
  
  
  METHODS
  Two patients with abdominal aortic aneurysms with aortocaval fistula.
  
  
  METHODS
  Both patients had an endovascular repair of their aortic aneurysms.
  
  
  RESULTS
  The aneurysms were successfully treated in both patients, without any endoleak on completion angiography. Apart from a transient type II lumbar endoleak in one of the patients, no endoleak was found after 3 and 12 month follow-up. Seven other cases have been published, reporting one type II and one type Ic endoleak.
  
  
  CONCLUSIONS
  We found no evidence that endovascular repair of abdominal aortic aneurysm with aortocaval fistula is associated with a higher incidence of persistent endoleak.
