Twenty five carotid endarterectomies were performed in 24 patients with cerebral ischemia due to atherosclerosis. Four of these patients were asymptomatic, 7 suffered from hemispheric TIA (hemispheric attack group), 7 suffered from nonhemispheric TIA (nonhemispheric attack group) and other 6 had previous completed stroke (completed stroke group). The average length of follow-up study was two and half years with a range of 2 months to 6 years. Completed strokes occurred in 1 patient following the operation and in 3 patients during the follow-up period (16.7％). Two patients were reoperated upon because of recurrent carotid stenosis (8.3％). Four patients continued to have neurologic symptoms postoperatively. Ultimately 10 of 24 patients had some neurologic complications even following carotid endarterectomies (41.7％). The first postoperative year was the worst period because almost all late neurologic complications occurred in that time. Kaplan-Meier's analysis demonstrated a relatively favorable result in the hemispheric attack group among these 3 groups. The completed stroke group was followed by that and the nonhemispheric attack group was proved to be the worst, although there was no statistical significance.
