Cerebral oximetry is a noninvasive bedside monitor for cerebral oxygen saturation (rSO2). A patient with a thoracic aneurysm underwent combined surgical and endovascular repair. A sudden decrease in right rSO 2 led to the finding of acute innominate artery dissection. Immediate repair was instituted. Sudden asymmetry of rSO2 may be a warning sign of underlying pathology.
