Therapy Evaluation in Patients With Minor Stroke and Large Vessel Occlusion

It was reported that about two third of the stoke patients might present with minor or mild stroke symptoms. 20-40% of those minor stroke patients had large vessel occlusion (LVO). AIS patients with LVO and low NIHSS are common and has been associated with early neurological deterioration and worse outcomes. Until now, the best therapy strategy for the acute stoke patients with minor stroke and large vessel occlusion is unknown. Thus, we sought to (1) explore the potential predictors of acute neurological deterioration and 90-day clinical outcome; (2) and evaluate the best therapy strategy.
