The results demonstrated that the patients in the PCC(+) group were significantly older than the patients in the PCC(−) group, and the incidence of the preoperative cerebral disease history in the patients of the PCC(+) group was significantly higher than those of the PCC(−) group. The Euro SCORE II of patients in the PCC(+) group was dramatically higher than the patients of the PCC(−) group
