[Occlusion of the distal aorta].
Between 1984 and 1992, 79 patients were operated for occlusion of the infrarenal abdominal aorta. 12/79 (15%) of the patients underwent emergency procedure for an acute Leriche syndrome. 67/79 (85%) of the patients with a chronic occlusion were treated electively. The surgical management includes in our series in 57/79 (72%) cases aortoiliac or aortofemoral prosthetic bypass, in 11/79 (14%) cases aortoiliac endarterectomy, in 6/79 (8%) cases embolectomy and in 5/79 (6%) extraanatomical axillofemoral bypass. For chronic total occlusion of the aorta the most common procedure was prosthetic bypass in anatomical position. For emergency cases embolectomy was performed in 42%. Early morbidity rate was 26% (21/79). The most frequent complications were thromboembolic events in 7 patients, myocardial infarction in 4 patients and renal insufficiency in 4 cases. The 30-day mortality 2.5% (2/79); the cause in both cases myocardial infarction. For atherosclerotic occlusive disease of the infrarenal abdominal aorta the prosthetic bypass is the first-choice surgical procedure. For embolic occlusions and for risk patients other less burdening procedures are available.
