Inflammatory aortic arch aneurysm with total occlusion of cervical branches

We surgically replaced the aortic root and the complex arch in a patient with aortitis syndrome with total occlusion of the cervical branches. Cerebral perfusion was being maintained through the reversed flow of the vertebral artery from the bilateral mammary arteries. Though cerebral perfusion was continued through the prosthetic grafts attached to the subclavian arteries during the procedure, bilateral watershed cerebral infarction corresponding to the most distal part of the anterior- and middle cerebral arterial system developed. With regard to the near infrared spectroscopy as a brain monitoring method, we sought to discuss the limitations.
