Carotid endarterectomy and abdominal aoritc aneurysm repair: are these reasonable treatments for patients over age 80?
Due to the aging of America, increased numbers of very elderly patients require peripheral vascular surgery. From April 1980 to November 1997, 191 patients age 80 years or older had carotid endarterectomy (CEA) and/or abdominal aortic aneurysm (AAA) repair at Loma Linda University Medical Center. The total perioperative stroke and death rate in the CEA group was 2.9 per cent. Mean postoperative cumulative survival in this group was 8.4 years. The cumulative stroke-free survival rate was 95.5 per cent for all yearly postoperative intervals up to 12 years. The perioperative mortality rate was 10.7 per cent in the nonruptured AAA group and 53.8 per cent in the ruptured AAA group (P < 0.00001). Mean cumulative survival was 8.6 years in the nonruptured AAA group and 1.1 years in the ruptured AAA group (P = 0.0001). These data support the conclusion that CEA and nonemergent AAA repair in octo- and nonagenarians are safe and effective in prolonging stroke-free and rupture-free survival. The utility of ruptured AAA repair in this age-group is less clear.
