Abstract:
Objective To compare the effect of brain unilateral and bilateral antegrade selective cerebral perfusion (ASCP) during a hybrid approach to DeBakey type Ⅰ aortic dissection and to provide the clinical evidence for the selection of cerebral perfusion methods of aortic dissection surgery.Methods Among the 56 patients undergoing a hybrid approach to DeBakey type Ⅰ aortic dissection from January 2009 to June 2011,24 were enrolled in the study.They were randomly divided into a unilateral ASCP group (n =11) and a bilateral ASCP group (n =13).The patients in both groups underwent cognitive ability test,brain CT scan,cerebrovascular and aortic CTA examinations before and after procedure.The general information,intraoperative conditions and neurological function in the patients of both groups were compared.Results There was no difference in the general data between the unilateral and bilateral ASCP groups.There were no significant differences among the intraoperative cardiopulmonary bypass time (125.2 ± 34.4 min vs.132.1 ± 45.4 min; t =- 0.278,P =0.784),aortic cross-clamping time (54.5 ± 23.6 min vs.61.6 ± 27.5 min; t =-0.149,P =0.883),cerebral perfusion time (30.9 ± 13.2 min vs.31.7 ± 14.5 min; t =- 1.283,P =0.213),right radial artery pressure (57.6 ± 15.5 mm Hg vs.60.7 ± 14.3 mm Hg; t =0.758,P =0.457),and arterial oxygen pressure (465.6 ± 62.4 mm Hg vs.488.4 ± 72.5 mm Hg; t =- 1.894,P =0.071 ).There were no surgery and recent death in both groups.There were no significant differences among the mechanical ventilation time (33.5 ± 14.6 h vs.37.8 ± 12.3; t =- 1.009,P =0.162),time awake after surgery (5.2 ± 2.4 h vs.5.5 ± 3.1 h; t =0.876,P =0.195),and intensive care unit stay time (7.5 ± 3.1 d vs.8.2 ± 3.5 d; t =-0.186,P =0.427).There was no new permanent neurological dysfunction in both groups.One patient had transient neurological impairment in each group.The cognitive function scores after surgery in the unilateral ASCP group (50.1 ± 14.8 vs.47.3 ± 15.2; t =1.005,P =0.126) and in the bilateral ASCP group (52.1 ± 13.7 vs.48.6 ± 16.5; t =0.576,P =0.254) were slightly lower than those before procedure,however,there was no significant difference; there was also no significant difference in the unilateral and bilateral ASCP groups before (t =-0.887,P =0.385) and after procedure (t =-0.953,P =0.351).Conclusions Under the circumstance of complete circle of Willis,the brain protective effect of the unilateral and bilateral ASCP in patients undergoing a hybrid approach for DeBakey type Ⅰ aortic dissection had no significant difference,and more simple and convenient unilateral ASCP can be used.
