Ten patients with distal aortic arch aneurysm underwent prosthetic graft replacement using moderately hypothermic cardiopulmonary bypass and selective cerebral perfusion via antero-axillary thoracotomy. Central cannulation was performed in the ascending aorta and venous drainage from the right femoral vein. The mean patient age was 74 years and the mean surgical duration was 5 h and 12 min. One patient died of multiple cerebral embolisms. Nine patients survived without major complications. Anastomosis between the vascular graft and the distal aorta can be easily achieved via left thoracotomy. Moderate hypothermia provides less coagulopathy and is less invasive. The rate of cerebral complications was acceptable. This technique is preferable for surgical treatment of the distal aortic arch.
