    Abstract:
    Resection of the abdominal aortic aneurysm is being performed with decreasing operative mortality and morbidity. Among 190 patients undergoing this procedure at the Ottawa Civic Hospital between 1970 and 1975, 53 (28%) had a ruptured aneurysm and 137 (72%), a nonruptured aneurysm. Mean age of the patients was 66.2 years. Concomitant disease was frequent, 73% of patients having two or more associated diseases; the average number of associated diseases per patient was 2.25. Operative mortality in the group with ruptured aneurysms was 51%, and in the group with nonruptured aneurysms, 4%. Postoperative morbidity was 85% among those with a ruptured aneurysm, 67% among those with imminent rupture before operation and 34% among the others with a nonruptured aneurysm. Graft complications occurred in 15% of those with a ruptured aneurysm and 9% of those with a nonruptured aneurysm. Among survivors of the operation 73% and 81% of those with a ruptured and a nonruptured aneurysm, respectively, are known to be alive. In both groups causes of late death included infection or thrombosis of the graft and mesenteric thrombosis, as well as causes unrelated to the operation. Surgical management of the abdominal aortic aneurysm is advocated in all but patients at poor risk for operation who have asymptomatic aneurysms less than 6 cm in diameter.
