title: [Prevention and management of frequent complications after endovascular repair of infrarenal abdominal aortic aneurysm].
abstract: OBJECTIVE
  To prevent and manage frequent complications after endovascular repair of infrarenal abdominal aortic aneurysm (AAA).
  
  
  METHODS
  The data of 71 cases of infrarenal abdominal aortic aneurysm (AAA) treated by endovascular repair were analysed retrospectively. The reasons, managements, results and prognosis of frequent complications were investigated.
  
  
  RESULTS
  Seventy-one cases of infrarenal AAA were treated by endovascular repair with 100% success rate. There was no surgical conversion to open aneurysm repair. There were 8 cases of primary endoleak, 1 case of nervous complication and acute thrombosis. An average follow-up period was 26 +/- 5 months. Three persistent endoleaks and 4 secondary endoleaks were found during the follow-up period. The endoleak rate was 9.8% (7/71) within 1 month postoperatively and mortality rate was 1.3% (1/71). Total mortality rate was 4.2% (3/71). Two patients died from acute myocardial infarction and one from acute heart failure.
  
  
  CONCLUSIONS
  Endovascular treatment of abdominal aortic aneurysm is technically feasible and can effectively exclude aortic aneurysms from the circulation. Endoleak is a chief complication after endovascular repair of infrarenal AAA.Additional procedures and follow up are very important. Endoleak with enlarged aneurysm should be treated actively.
