title: The true incidence of ruptured abdominal aortic aneurysms.
abstract: The number of ruptured abdominal aortic aneurysms (RAAA) was documented over an 8-year-period in a known population age group. Patient figures were collected from the operative and post-mortem registers in the Worthing Health District. The overall mean incidence of RAAA was 13.9/100,000 patient years, although the incidence was noted to increase from 9.2 to 17.5/100,000 patient years during this period. The incidence in the male population rose from 4.7/100,000 for those in the fifth decade to 184.8/100,000 for those above 80. For patients undergoing operation, the peri-operative survival was 38%, however the overall survival was 11% as 64% of patients died at home. These figures demonstrate an increasing incidence of ruptured AAA. They also add support to the need for screening of asymptomatic abdominal aortic aneurysms and elective repair if the incidence and hence mortality is to be reduced.
