title: Perioperative outcomes for elective open abdominal aortic aneurysm repair since the adoption of endovascular grafting procedures.
abstract: OBJECTIVE
  The objective of this study was to evaluate and compare our perioperative outcomes for open abdominal aortic aneurysm (AAA) between the pre-endovascular aneurysm repair (pre-EVAR) and EVAR eras and to analyse whether the AAA that was excluded from EVAR could affect the perioperative outcome.
  
  
  METHODS
  The Kurume University Hospital vascular registry was reviewed to identify all patients undergoing an elective open AAA repair from January 2004 through November 2006 (pre-EVAR era, n = 99) and from December 2006 through June 2010 (EVAR era, n = 125). The early clinical outcomes between the two groups were compared.
  
  
  RESULTS
  In the EVAR era, the proportion of EVAR in all elective AAA repairs was 43.4%. The EVAR era had a significantly higher proportion of very elderly patients over 80 years of age (23.2% vs. 11.1%, P = 0.0391). The morbidity rates were similar between the two groups (22.3% vs. 24,8%) and the mortality rate was 0% for both.
  
  
  CONCLUSIONS
  Despite the increased complexity of OAR in the EVAR era, we believe that OAR remains a valid procedure for AAA repair.
