Surgical treatment of occlusive lesions of thoraco-abdominal aortic segment

Forty-nine patients with the occlusive lesions of the thoraco-abdominal aortic segment, congenital hypoplasia (13 patients) and non-specific aortitis (36 patients) were operated on. Operations were performed under moderate hypothermia (+30-31 degrees C) through the left thoracophrenolumbotomic approach. In the majority of patients reconstruction of the aorta was done by means of its resection and replacement. In 9 patients with congenital hypoplasia we performed aortic reconstruction only, and in 4 it was combined with plastic procedure on the coeliac trunk. In 25 patients with non-specific aorto-arteritis aortic replacement was combined with revascularization of the visceral (renal) arteries. In this group reconstruction of the aorta and visceral branches was performed in 7 cases, that of the aorta and renal arteries in 62 and simultaneous reconstruction of the aorta, visceral and renal arteries in 16 cases. Total mortality was 6.1% (3 patients). There was no mortality in patients with aortic hypoplasia.
