Endovascular Therapy Versus Best Medical Treatment for Acute Large Vessel Occlusion Stroke With Low NIHSS

Patients presenting with mild symptoms of acute ischemic stroke are common and account for approximately half of all acute ischemic stroke. About 30% of patients with minor stroke have a 90-day functional disability. Radiologically proven a large vessel occlusion (LVO) in patients with minor stroke is a well-established predictor of poor outcomes, while the poor outcomes following best medical management in patients with minor stroke with the underlying presence of a LVO are mainly driven by the occurrence of early neurological deterioration (END). Considering the well-known strong association between lack of arterial recanalization and END, endovascular therapy (EVT) appears as an attractive option to improve functional outcomes for LVO-related patients with stroke with mild symptoms. Whether EVT is safe and effective in patients with mild stroke with an LVO is currently debated, since these patients were typically excluded from the pivotal EVT trials. The current study aimed to further test the hypothesis that endovascular therapy would be superior to medical management with respect to functional recovery among low NIHSS patients caused by acute large-vessel occlusion in the anterior circulation.
