A prospective analysis of 421 patients undergoing coronary artery bypass graft (CABG) surgery as the sole cardiac procedure was carried out to assess frequency central nervous system (CNS) complications. In all, 451 variables were assessed in each patient. Stroke occurred 5.2% but severe only 2%. Prolonged encephalopathy 11.6% usually resolved before discharge. No statistically significant pre- or intraoperative risk for CNS complications found; specifically, age pump times excess two hours not factors. Postoperative use an intraaortic balloon and pressor agents significantly correlated with prolonged encephalopathy. The injury CABG is similar that other forms open heart surgery, there has been little change over past seven years. Possible mechanisms damage during are discussed.
