Abstract

Cerebrovascular disease is the third cause of death in industrialized countries. Carotid stenosis is associated with an increased risk of acute and chronic infarction. Patients with 80–99% lesions had a 20.6% annual event rate. The main factor that appears to predict increased risk for future stroke is progression of stenosis. A significant carotid stenosis can be found in approximatively one third of patients with cerebral ischemia. Overall carotid atherosclerosis is responsible for approximately 20% of all cerebral ischemic strokes. At 2 years of follow-up, the risk of a repeat stroke is 28 and 13% for symptomatic stenoses of 70–99% and 50–69%. Carotid endarterectomy is now well established as a way to prevent infarction in the presence of carotid stenosis either symptomatic and of a higher grade than 50%, or symptomatic or asymptomatic of a higher grade than 70%. This was proven by two randomized clinical trials, the European Carotid Surgery Trial [3] and the North American Symptomatic Carotid Endarterectomy Trial [1].
