Cerebrovascular disease is the third most frequent cause of death in western society. In Europe over one million new cases of stroke are reported each year, with a 30 percent mortality and a 60 percent incidence of substantial disability among the survivors. In 19T3 it was estimated that over 7 billion dollars was spent annually in the initial hospital care of these patients (1,2). It is generally estimated that 60–70 percent of strokes are due to thromboembolism (3,4). The importance of extracranial atherosclerotic disease in the production of stroke has been recognised only in the last 30 years (5,6). Recent studies have shown up to 88% of patients with cerebral ischaemia to have extracranial artery lesions (7,8) with the majority situated at the carotid artery bifurcation (9). There are two basic mechanisms by which carotid artery lesions produce cerebral ischaemia (A) reduced flow from a high grade stenosis or occlusion and (B) from emboli generated from the region of atheromatous plaques.
