The incidence of stroke in the perioperative period following carotid throm boendarterectomy has been reported to be 1% to 10%. 1,2,3 It is generally ac cepted that neurologic deficits result from temporary cerebral ischemia during carotid occlusion, reperfusion, emboli or carotid artery thrombosis.
