title: Infrarenal aortic aneurysms. Asymptomatic versus symptomatic.
abstract: Between 1978 and 1983, 103 patients underwent operations for infrarenal abdominal aortic aneurysms (AAA). Fifty-seven patients (group I) had elective procedures without a death and with a morbidity of 19 per cent. Thirty-three patients (group II) had symptomatic but nonruptured AAA, while 13 patients (group III) had ruptured AAA. In group II, the mortality was 6 per cent and in group III, 37 per cent, while the morbidity was 33 and 100 per cent, respectively. There was no morbidity or mortality from pulmonary emboli, as all patients had prophylactic inferior vena cava interruption at the time of operation for their AAA. These results substantiate the necessity for early and aggressive treatment in patients with AAA, as the mortality and morbidity, once symptoms develop, remain prohibitive.
