Clinical results of cardiopulmonary bypass with selective cerebral perfusion for aneurysm of the ascending aorta and the aortic arch.
The purpose of this report is to describe our experience using cardiopulmonary bypass with selective cerebral perfusion in 10 patients whose aneurysms required cross-clamping the aorta and brachiocephalic vessels. Cerebral perfusion was carried out with individual roller pumps. Flow rate was 11.2 +/- 4.8 ml per kilogram of body weight per minute to the right axillary artery, 8.5 +/- 1.0 to the right common carotid artery, 7.0 +/- 2.0 to the left common carotid artery, and 3.9 to the left subclavian artery. All the patients came off bypass smoothly, and only 3 required small amounts of inotropic agents postoperatively. One patient with mycotic aneurysm died in the fourth postoperative week of massive bleeding due to disruption of the suture line. No cerebral complications were experienced. The operative results of this series suggest the usefulness of cardiopulmonary bypass with selective cerebral perfusion, and reasonably favorable outlook for patients with aneurysm involving the aortic arch and the ascending aorta.
