Tirofiban for Reduction of Thromboembolic Events in Endovascular Unruptured Aneurysm Repair (TEAR)
March 5, 2024 updated by: Beijing Tiantan Hospital
Prophylactic Administration of Tirofiban for Preventing Thromboembolic Events in Stent-assisted Coiling and Flow Diversion Treatments of Unruptured Intracranial Aneurysms
To explore whether administering tirofiban in stent-assisted coiling/flow diverting treatments for participants with unruptured intracranial aneurysms can reduce new ischemic lesions on postoperative DWI sequences compared to conventional dual antiplatelet therapy.

Detailed Description
This is a single-center, open-label, assessor-blinded randomized controlled trial.
Participants with stent-assisted coiling/flow diverting for unruptured intracranial aneurysms will be enrolled and randomized into two groups: Tirofiban group-after femoral artery puncture, initial infusion of 0.4μg/kg body weight/minute over 30 minutes, followed by a continuous infusion of 0.1μg/kg body weight/minute for 24 hours.
Meanwhile, routine dual antiplatelet therapy (aspirin 100 mg/day, clopidogrel 75 mg/day) will be administered.
Placebo group-100 mg/day aspirin and 75 mg/day clopidogrel.
The primary effectiveness endpoint is the numbers and volumes of ischemic lesions on diffusion weighted imaging (DWI) within 48 hours after procedure.
