Yet, with all improvement, rupture of aneurysm has continued to be associated with high rates of mortality. At the Department of Surgery of Cologne University, between 1963 and 1985, operations were performed on 681 patients for abdominal aortic aneurysm. Asymptomatic aneurysm were surgically removed from 41.7 per cent of them, while 27.5 per cent underwent surgery in symptomatic stages. Aneurysm had ruptured in 210 patients. Operative mortality accounted for 5.3 per cent of all asymptomatic patients. High mortality rates among patients with ruptured aortic aneurysms were attributable to preoperative shock. Only 16.3 per cent of patients survived in this group. The mortality rate among patients without shock amounted to 39.5 per cent. | lld:pubmed |
