The incidence and etiology of brain dysfunction after conventional coronary artery bypass surgery using cardiopulmonary bypass are reviewed. Stroke rates and incidences of cognitive dysfunction from various studies are considered. Mechanisms of injury including cerebral embolization as detected by transcranial Doppler and evidence for postoperative cerebral edema are discussed. Evidence for lower overall postoperative morbidity, and for a lower incidence of cognitive dysfunction specifically, after nonpump coronary revascularization is presented.
