[Prognosis after surgery of infrarenal abdominal aortic aneurysm]

During the period from January 1972 to September 1984, 285 patients were admitted and treated operatively for abdominal aortic aneurysm (AAA). At operation a non-ruptured AAA was found in 177 patients and a ruptured AAA in 108 patients. Advanced age and reduced renal function were found by employment of Cox's regression analysis to influence the peroperative and postoperative mortalities. The commonest cause of postoperative death was renal failure both in cases of non-ruptured and ruptured AAA. The commonest causes of late deaths were coronary occlusion, malignant disease, cerebral haemorrhage and haemorrhage from the anastomosis.
