Complete reperfusion mitigates influence of treatment time on outcomes after acute stroke.

Background: Time to reperfusion following endovascular treatment (ET) predicts outcomes after acute ischemic stroke (AIS).

Objective: To assess the time-outcome relationship within reperfusion grades in the North American Solitaire Acute Stroke registry.

Methods: We identified patients given ET for anterior circulation ischemic stroke within 8 h from onset and in whom reperfusion was achieved.
