Twenty men had their cerebral function measured preoperatively and three months after carotid endarterectomy using the Halstead-Reitan neuropsychological test battery. Thirteen patients were cerebrally impaired preoperatively, but 12 of them improved appreciably after surgery. Changes in internal carotid arterial blood flow measured preoperatively showed no significant correlation with the improvement in neuropsychological status. We think that carotid endarterectomy carries an even better prophylaxis for the brain as a whole than had been thought.
