Abstract: Objective To review the complications after endovascular aneurysm repair (EVAR) of high-risk abdominal aortic aneurysms in our medical center.Methods Fifty eight elective high-risk EVAR cases from January 2008 to December 2013 were analyzed retrospectively.Results The technical success rate was 96.6％ (56 of 58 patients).The overall complication rate in perioperative period was 32.8％ (19/58).Eleven systemic complications (19.0％),16 primary endoleaks (27.6％),7 access of site complications(12.1％) were observed.The follow-up rate was 86.2％ (51/58).During the follow up period,the mortality was 7.8％ (4/51),the re-intervention rate was 7.8％ (4/51).The overall complication rate was 29.4％ (15/51),including systemic complications (2/51),secondary endoleak (9.8％) and graft-related complications (11.8％,6/51).Conclusions Endoleak,graft-related complications continue to be the main causes of re-intervention in high-risk aneurysm patients after EVAR.
