The Risk of Surgical Therapy to Patients with Unilateral Stenosis and Contralateral Occlusion of the Carotid Artery

A total of 384 supra-aortic branches were operated in 318 patients. Forty-four operations were carried out on 35 patients with unilateral stenosis and contralateral occlusion of the internal carotid artery (aci). Eighteen patients were classified in stage IV. The symptomatology was largely determined by the occluded side (27 patients). In 23 cases only the stenosis was operated, in 3 cases only the occlusion. Both sides were operated in 9 cases. The rate of mortality within the first 30 days was 11.4 % (cerebral death: 2 patients, non-cerebral death: 2 patients). The rate of mortality within a time span of up to 10 years was 20 % (7 patients).
