title: Endoleaks after endovascular abdominal aortic aneurysm repair:  what one needs to know.
abstract: OBJECTIVE
  To review the current state of diagnosis, treatment, and outcomes of the different types of endoleaks after endovascular abdominal aortic aneurysm repair (endovascular aneurysm repair, EVAR).
  
  
  RESULTS
  Endoleaks are the most frequent complication after EVAR, the most common indication for secondary interventions, and the most common cause of rupture after EVAR. Imaging is critical for detecting endoleaks. Type I and III endoleaks require urgent intervention to prevent aneurysm rupture. Intervention for other endoleaks or endotension is indicated if the aneurysm sac continues to grow during follow-up. The majority of endoleaks can be treated with endovascular techniques. Open surgical conversion may be considered if the risk of aneurysm rupture is high and if no endovascular options are available or if they have failed.
  
  
  CONCLUSIONS
  Endoleaks continue to be a challenge and this article discusses the different treatment options for endoleaks after EVAR. Long-term follow-up after EVAR is required to diagnose and treat endoleaks before they result in aneurysm rupture. The majority of endoleaks can be treated with endovascular techniques, although open surgical interventions may be required in selected patients.
