Intra-arterial Alteplase for Acute Ischemic Stroke After Mechanical Thrombectomy

Summary

A multicenter, prospective, open-label, blinded endpoint, randomized controlled trial aiming at evaluating the efficacy and safety of intra-arterial recombinant human tissue plasminogen activator (rt-PA) after successful recanalization of acute large vessel occlusion in the anterior circulation by mechanical thrombectomy in improving the 90-day functional outcome.
