Degree of Conjugate Gaze Deviation on CT Predicts Proximal Vessel Occlusion and May Expedite Endovascular Therapy

Purpose: Recent trials have demonstrated superior outcomes with combination IV-tPA and endovascular therapy (EVT) within 6 hours of symptom onset in patients with proximal vessel occlusion (ICA, M1, or proximal M1/M2) compared to IV-tPA alone. The current standard of diagnosis for consideration of EVT is CT angiogram (CTA). Unfortunately, not all hospitals are equipped with CTA, and the decision to transfer to tertiary centers is often based on nonenhanced CT. Ipsilateral conjugate gaze deviation (CGD) is associated with worse outcomes and larger infarcts in acute ischemic stroke.
