Intra-Arterial Tirofiban After Complete Recanalization for Acute Intracranial Large-Vessel Occlusion

The goal of this clinical trial is to learn if immediate intra-arterial tirofiban after complete recanalization can improve recovery in adults with acute ischemic stroke caused by anterior circulation large-vessel occlusion. It will also learn about the safety of this treatment. The main questions it aims to answer are:

Does immediate intra-arterial tirofiban after complete recanalization increase the number of participants with good functional outcome at 90 days? Does this treatment increase the risk of symptomatic intracranial hemorrhage or other important bleeding events?

Researchers will compare immediate intra-arterial tirofiban with no intra-arterial tirofiban after complete recanalization to see if tirofiban improves recovery and is safe.

Participants will:

Be enrolled after mechanical thrombectomy achieves complete recanalization Be randomly assigned to receive intra-arterial tirofiban or no intra-arterial tirofiban Receive follow-up assessments during hospitalization and at 90 days
