Detection of Anterior Circulation Large Artery Occlusion in Ischemic Stroke Using Noninvasive Cerebral Oximetry.

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.
