NCT07818083

Brief Summary

This multicenter prospective randomized controlled study will enroll patients with ruptured intracranial aneurysms receiving stent-assisted coiling across multiple Chinese medical centers. The investigators aim to evaluate the efficacy and safety of tirofiban-enhanced antiplatelet therapy versus conventional dual antiplatelet treatment on the 90-day neurological prognosis and major adverse cerebrovascular events of enrolled subjects.

Study Arms (2)

Enhanced Antiplatelet Group

EXPERIMENTAL

All subjects receive oral aspirin 300mg plus clopidogrel 300mg 2 hours before operation. After stent deployment, tirofiban 5μg/kg is intravenously bolus injected within 20 seconds, followed by continuous intravenous infusion at 0.075μg/(kg·min) for 24 hours. Long-term oral aspirin 100mg and clopidogrel 75mg daily are administered for 90 days after bridging antiplatelet therapy.

Drug: Tirofiban+Oral Dual Antiplatelet Therapy

Conventional Antiplatelet Group

PLACEBO COMPARATOR

All subjects receive oral aspirin 300mg plus clopidogrel 300mg 2 hours before operation. After stent deployment, equal volume normal saline is intravenously bolus injected and continuously pumped for 24 hours with the same duration. Long-term oral aspirin 100mg and clopidogrel 75mg daily are maintained for 90 days.

Drug: Dual Antiplatelet Therapy plus Normal Saline

Interventions

Preoperative oral loading dose: Aspirin 300 mg and Clopidogrel 300 mg. After stent deployment, tirofiban 5 μg/kg intravenous bolus, then continuous infusion at 0.075 μg/(kg・min) for 24 hours. Postoperative maintenance: oral Aspirin 100 mg and Clopidogrel 75 mg once daily for 90 days.

Enhanced Antiplatelet Group

Aspirin 300 mg and Clopidogrel 300 mg. After stent deployment, equal volume normal saline is given via intravenous bolus and continuous infusion for 24 hours. Postoperative maintenance: oral Aspirin 100 mg and Clopidogrel 75 mg once daily for 90 days.

Conventional Antiplatelet Group
