Medical and surgical emergencies occasionally present as ruptured abdominal aortic aneurysms (RAAA). To assess benefits of laparotomies and adverse effects of unnecessary operations, the authors reviewed their experience.

Thirteen patients, 9 women, 4 men (mean age: 72 years, range: 41-85) underwent emergency laparotomy between 1988 and 1996 for presumed RAAA and were found to have other surgical or medical emergencies.

All the patients presented with hypotension, 12 had abdominal or back pain, four had pulsatile abdominal mass. Rupture was not excluded by computed tomography scan in three or by ultrasonography in two patients. Laparotomy disclosed intact abdominal aorta in all, but seven patients had abdominal aortic aneurysm. Of five surgical emergencies, laparotomy was indicated in four: three for ruptured visceral artery aneurysms, one for perforated duodenal ulcer. The fifth patient required thoracotomy for ruptured thoracic aneurysm. Four of eight medical emergencies were myocardial infarctions. One iatro genic complication required reoperation for bleeding. Mean hospital stay was 18 days; mean hospital charges were $40,771. Seven (54%) early deaths occurred; none were caused directly by the operation.

Laparotomy was indicated in one third of deceptive emergencies that present as RAAA. Although mortality, morbidity, and costs were high, iatrogenic surgical complica tions were rare and deaths were not caused by unnecessary operations.
