Intra-arterial Recombinant Human TNK Tissue-type Plasminogen Activator (rhTNK-tPA) Thrombolysis for Acute Large Vascular Occlusion After Successful Mechanical Thrombectomy Recanalization

Summary

The goal of this clinical trial is to evaluate whether intra-arterial (IA) rhTNK-tPA thrombolysis can improve neurological outcomes in acute large vessel occlusion patients after successful mechanical thrombectomy (MT) recanalization between 4.5- 24 hours from symptom onset. Participants enrolled will be randomly assigned to study or control arm with a 1:1ratio. Study group will receive IA rhTNK-tPA thrombolysis (0.125 mg/kg, Max 12.5mg) plus best medical management, and control receive best medical management alone.
