Detection of Anterior Circulation Large Artery Occlusion in Ischemic Stroke Using Noninvasive Cerebral Oximetry [Brief Report]

Background and Purpose—Large artery occlusion (LAO) in ischemic stroke requires recognition and triage to an endovascular stroke treatment center. Noninvasive LAO detection is needed to improve triage.Methods—Prospective study to test whether noninvasive cerebral oximetry can detect anterior circulation LAO in acute stroke. Interhemispheric ΔBrSO2 in LAO was compared with controls.Results—In LAO stroke, mean interhemispheric ΔBrSO2 was −8.3±5.8% (n=19), compared with 0.4±5.8% in small artery stroke (n=17), 0.4±6.0% in hemorrhagic stroke (n=14), and 0.2±7.5% in subjects without stroke (n=19) (P
