ABSTRACT
Objective To study the postoperative cognitive dysfunction (POCD) in elderly patients after off‐pump coronary artery bypass grafting (OPCABG)and its risk factors ,and the association between cerebrovascular function assayed by 320 dynamic volume CT and POCD .Methods Two hundred and thirteen elderly patients selected for OPCABG were divided into patients group (n=28) and control group (n=185) .The patients underwent 320 dynamic volume CT to show their cerebrovascular ,neurological and cognitive functions .The patients were assessed on day 14 after operation .The risk factors for POCD and the association between CT perfusion imaging parame‐ters and POCD w ere comparatively analyzed .Results T he incidence of cerebrovascular disease , diabetes mellitus ,CTA‐detected severe cerebrovascular stenosis and abnormal cerebral pufusion was significantly higher in patients group than in control group (P< 0 .01) .Logistic regression analysis showed that cerebrovascular disease history and abnormal cerebral pufusion were the in‐dependent risk factors for POCD (OR= 1 .837 ,95% CI:1 .075 -3 .141 ,P= 0 .026 ;OR= 3 .224 , 95% CI:2 .073-5 .013 ,P=0 .000) .Conclusion Early detection of abnormal cerebrovascular ste‐nosis ,poor cerebral perfusion and maintainence of stable blood glucose play an important role in reducing the incidence of POCD in elderly patients after OPCABG .
