AORTIC-ARCH ANEURYSM REPAIR USING SELECTIVE CEREBRAL PERFUSION

Seventy-seven patients underwent aortic arch aneurysm repair using sel ective cerebral perfusion from January 1987 to August 1992. Early and long-term results and preoperative and postoperative cerebral function were evaluated. Cerebral function was assessed by the mini mental sta te-Himeji test and the Wechsler adult intelligence scale. Thirty-six p atients had true aneurysms, and 41 had dissection. Hospital mortality for true and dissecting aneurysms was 19.4% and 7.3%, respectively. Th e 5-year actuarial survival rates for true and dissecting aneurysms we re 59.0% and 65.3%, respectively (not significant). There were no sign ificant differences in test scores before or after operation. Repair o r replacement of the aortic arch using selective cerebral perfusion is a safe procedure with acceptable hospital mortality.
