Perioperative prognostic factors in patients with ruptured abdominal aortic aneurysms treated in the intensive care unit.

Background: The incidence of abdominal aortic aneurysm has been estimated at 20-40 cases per 100,000 per annum. The disease is often asymptomatic; in many cases, its first symptom is shock caused by a ruptured aneurysm. The aim of the present study was to assess retrospectively the selected perioperative factors in patients hospitalised in the intensive care unit (ICU) after repair of ruptured abdominal aortic aneurysm.
