Cerebral oxygen desaturation after cardiopulmonary bypass in a patient with raynaud's phenomenon detected by near-infrared cerebral oximetry.

Raynaud's phenomenon is characterized by episodes of arterial vasospasm precipitated by cold stress, usually affecting the digits of the hands. There is controversy about the occurrence of vasospasm in internal organ systems. In this report, we present a case of Raynaud's peripheral vasospasm accompanied by cerebral oxygen desaturation as detected by near infrared cerebral oximetry after separation from cardiopulmonary bypass.
