[Selective cerebral perfusion and pharmacological cerebral protection in the patients with aortic arch aneurysm].

We have developed the protocol for selective cerebral perfusion (SCP) and pharmacological cerebral protection, and used it successfully in cases of aortic arch aneurysm. The subjects of the present study were 34 patients (28 males, 6 females) whose aortic arch aneurysm were surgically treated. Preoperative brain CT and brain scintigram showed high incidence of brain ischemia. However only 4 patients experienced a neurological episode. We conclude that our SCP technique and pharmacological cerebral protection are useful component to surgery of the aortic arch.
