The role of cerebral oximetry monitoring in off-pump coronary artery bypass surgery of Moyamoya disease.

Moyamoya disease is a chronic cerebrovascular disease characterized by the development of compensatory collateral vessels due to progressive narrowing or obstruction of the intracranial arteries. Neurological complications after coronary bypass in patients with Moyamoya disease may be prevented by recent technical developments, surgical modifications, and cerebral monitorization. The objective of perioperative anesthetic management is to provide balance between oxygen supply and consumption of the brain.
