Abstract: | During the period January 1984-July 1988, 191 abdominal aortic aneurysms were encountered at Gosford District Hospital, NSW, a hospital that services an ageing population. These aneurysms were either repaired or found as the cause of death at post-mortem. During the study, the rate of elective repair rose from 0.25/month during the first 2 years to 3.67/month in the latter 2.5 years. The mortality for repair of non-ruptured aneurysms was 0.9% compared with 55% for ruptured aneurysms. The 15-fold increase in elective repair resulted in the 58% reduction in the incidence of abdominal aortic rupture from 1.87/month to 0.79/month. The mortality rate from known aneurysms fell from 46% to 14% in the final 2 years. Elective aneurysm repair reduces the incidence of and death from abdominal aortic rupture in an ageing population. |
