Acute thrombosis of the non-aneurysmal abdominal aorta.

Fourteen patients admitted over a 9 year period with acute thrombotic occlusion of the non-aneurysmal abdominal aorta have been reviewed. Twelve patients underwent aortic bifurcation graft reconstruction, one thromboendarterectomy alone, and one a re-entry operation for dissection. Two patients (14%) died in the perioperative period. The mean postoperative survival of the remaining patients is to date 55 (range 4-93) months with a mean follow-up period of 69 (range 18-100) months. The results indicate these patients should be treated aggressively by early reconstructive surgery in the expectation that the majority will survive their operation and gain a useful extension to their lives.
