Jugular Bulb Oximetry in Patients with Cerebral Arteriovenous Malformation
Arterial blood flow directly through a shunt theoretically does not deliver oxygen to the brain tissue. The draining veins of an arteriovenous malformation (AVM) contain highly oxygenated blood , as evidenced by the intraoperative finding commonly denoted as red veins . The jugular bulb oxygen saturation (SjO2) has been demonsttrated to reflect global cerebral hyperemia or ischemia sensitively [3–6]. In addition, fiberoptic technology is now available for continuous monitoring of SjO2 [3–5].
