Abstract:
Objective To investigate the effect of flow management of cerebral perfusion during aortic arch surgery on the neurological complication.Methods From March 2007 to November 2011,189 patients underwent aortic arch surgery with hypothermic circulatory arrest plus antegrade cerebral perfusion in our department.The clinical data were analyzed retrospectively.According to the different methods of cerebral perfusion flow nanagement,patients were divided into two groups.Single pump with double limb (to the lower body and brain) perfusion was used in group A (96 patients),based on natural distribution of petfusion flow without control.Modified flow management was used in group B (93 patients).A magnetic flow sensor probes was installed on the brain perfusion limb to monitor and control the cerebral perfusion flow precisely (10 ml · kg-1 · min-1).Postoperative neurological complications were compared between two groups.Results There was no significant difference between the two groups in CPB time,aortic clamping time and circulatory arreating time.However,the morbidity of postoperative neurological complications in group B was much lower than that in group A (1.1％ vs 5.2％,P ＜0.05).Conclusion When performing antegrade cerebral perfusion during aortic arch surgery,precisely control of cerebral perfusion flow can reduce the morbidity of postoperative neurological complications effectively.
