The Efficacy of Vision, Aphasia, Neglect Assessment in Predicting Emergent Large Vessel Occlusion in Patients Presenting with a Cerebrovascular Accident to the Emergency Department.

Background: Early identification of patients with an emergent large vessel occlusion (ELVO) ischemic stroke is crucial in the Emergency Department (ED), as they are the ideal candidates for endovascular therapy.With this study, we have attempted to use Vision, Aphasia, Neglect (VAN) screening tool in the ED for rapid identification of ELVO ischemic stroke and compared its performance with the National Institute of Health Stroke Severity (NIHSS) scale.

Materials And Methods: A prospective observational study was conducted in the ED of a tertiary care hospital over 18 months among all suspected stroke patients.
