Long-Term Results of 102 Abdominal Aortic Aneurysms

Abstract

One hundred and two abdominal aortic aneurysmectomy were performed during 1973 to 1988. 87 patients underwent elective surgery (non-ruptured group). Comparatively, emergency surgery was carried out for 15 patients with ruptured aneurysms (Ruptured group).

Bifurcation prostheses were used for the aortic reconstruction following aneurysmectomy in all patients. (Cooley Double Velour Graft)

Postoperative morbidity occurred in 22 % (19/87) of the nonruptured group and in 47 % (7/15) of the ruptured group. Mortality occurred in 4.7% (4/87) of the nonruptured group and in 33% (5/15) of the ruptured group.

In late stage after aneurysmectomy there were two patients with anastomotic aneurysms. There were, however, no deaths related to aneurysmectomy and no graft occlusion. The cumulative 3-year and 5-year survival rate in the non-rup tured group was 80 % and 74 % respectively, whereas, in the ruptured group 73%.

The long-term results following the operative repair of an abdominal aneu rysm were satisfactory, despite the fact that the early operative results for patient having a ruptured aneurysm were poor. The abdominal aortic aneurysmectomy should be performed before ruptured to obtain the highest survival rate.
