title: Abdominal aortic aneurysm surgery for octogenarians.
abstract: OBJECTIVE
  To define the indications for abdominal aortic aneurysm (AAA) surgery in octogenarians.
  
  
  METHODS
  We reviewed septuagenarians and octogenarians with a nonspecific AAA diagnosed at our hospital between January, 1990 and June, 2006.
  
  
  RESULTS
  Among a total 628 patients seen, 306 were in their 70s (group A) and 108 were in their 80s or older (group B). The mortality rate associated with elective surgery was 1.9% in group A and 7.0% in group B. Of the survivors, 12 (5.7%) of 210 in group A and 8 (15.1%) of 53 in group B died within 2 years. Of the patients who did not undergo surgery, 8 of 53 in group A and 8 of 31 in group B had AAAs greater than 6 cm in diameter. The rupture-free rates of AAAs greater than 6 cm in diameter were 64% at 1 year and 0% at 4 years in group A, and 88% at 1 year and 26% at 3 years in group B. The rupture-free rates of AAAs smaller than 6 cm in diameter were 95% at 3 years and 85% at 5 years in group A, and 100% at 5 years in group B.
  
  
  CONCLUSIONS
  We concluded that AAAs over 6 cm in diameter were an appropriate indication for surgery in octogenarians.
