Outcomes of mechanical endovascular therapy for acute ischemic stroke: a clinical registry study and systematic review.

Recanalization is a powerful predictor of stroke outcome in patients with arterial occlusion. Intravenous recombinant tissue plasminogen activator is limited by its recanalization rate, which may be improved with mechanical endovascular therapy (MET). However, the benefit and safety of MET remain to be determined. The aim of this study was to give reliable estimates of efficacy and safety outcomes of MET.
