Ten patients underwent surgical treatment for type A aortic dissection from October 1986 to April 1989 using hypothermic cardiopulmonary bypass (CPB) with selective cerebral perfusion (SCP). CPB was begun with femoral artery cannulation. The right axillary artery (RAA) and the left common carotid artery (LCCA) were separately cannulated and perfused with CPB blood by individual pump heads. The average flow to the RAA was 5.4 +/- 1.2 ml/min/kg body weight (mean +/- SD) and 5.6 +/- 2.6 ml/min/kg body weight to the LCCA. The average blood pressure of the superficial temporal artery was 53.1 +/- 15.1 mmHg in the right side and 52.5 +/- 24.7 mmHg in the left. The nasopharyngeal temperature during SCP was maintained at 19.3-24.7 degrees C (mean, 21.1 degrees C). The SCP time ranged from 112 to 197 minutes (mean, 168 +/- 20.8 minutes). There was one operative death. She died of myocardial infarction 3 days after operation. There were two late deaths. One patient died of infection 3 months after operation and another died of cholecystitis 4 months after operation. Cerebral infarction developed in the last patient. Among the 10 patients it was only one neurological sequela, which was surmised to be caused by technical problem in carotid artery cannulation. The good cerebral protection was obtained in our experience by SCP as mentioned above.
