Brain protection is important during aortic arch surgery, especially in patients with cerebral ischemia. We clinically applied the effectiveness of a novel protocol of retrograde cerebral perfusion with intermittent pressure augmentation for brain protection in a canine model, as described in a previous report. Although, in our patient the brachiocephalic artery and left subclavian artery were occluded as a result of aortitis, there was a history of right cerebral infarction, recovery of consciousness, and no neurologic sequelae. Near-infrared oximetry showed recovery of intracranial blood oxygen saturation every time the pressure was augmented.
