Surgical Treatment of Abdominal Aortic Aneurysms in Octogenarians

Due to the increase in life span and the decrease in mortality associated with aortic surgery, many geriatric patients now undergo surgery for abdominal aortic aneurysms (AAAs). Therefore, we studied our surgical results for AAAs in an elderly population to assess the value of such operations. Twenty-six patients aged 80 years or older underwent surgery during an 11-year period from 1984 to 1994 at our institutions, and their outcomes were compared with those of 212 younger patients. The ratio of ruptured to non-ruptured AAAs was significantly higher in the older patients (aged 80 years or older) than in the younger patients (aged 79 years or younger), and aneurysm size in cases of non-rupture was greater in older patients than in younger patients. For octogenarians with non-ruptured AAAs, the survival rate was 85.7% at 5 years, compared with 43.6% at 3 years for those with ruptured AAAs, and these figures were not significantly different from those in younger patients. The present findings support the value of our active surgical approach for octogenarians with AAAs. We believe that an aggressive approach for octogenarians will decrease the incidence of ruptured AAAs and contribute to better patient survival.
