Patients with aortic arch aneurysms underwent surgery using a selective cerebral perfusion (SCP) method. For this purpose, a protocol for SCP was established on the basis of an animal experimental study. Our SCP procedure is performed at a perfusion rate of 6 ml/kg/min with the patient under deep hypothermia at 20 degrees C. ⋯ There was no definite production of lactate in the brain. Cerebral disorders considered to have been caused by SCP occurred in only two cases. It appears that cerebral metabolism can be maintained safely, and that our SCP method is useful during surgery for aortic arch aneurysms.
