摘要

Background There have been few reports on the use of tirofiban in ruptured intracranial aneurysms and the results were conflicting. However, the safety and efficacy of optimal dosage and the reasonable treatment course of tirofiban have not been determined. Objective To determine the safety and efficacy of a new protocol for its prophylactic tirofiban application during the endovascular treatment of ruptured intracranial aneurysms with no oral antiplatelet medications. Methods This retrospective study was based on 105 patients with ruptured aneurysms who underwent stent-assisted coiling at our institution between August 2017 and July 2020. Intravenous tirofiban was administered to patients after stent deployment. Tirofiban was administered as an intravenous bolus (5 µg/kg) over a 3 min period immediately after stent deployment, followed by a 0.06–0.08 µg/kg/min maintenance infusion for 12–24 h. Dual oral antiplatelet therapy was overlapped with half the tirofiban dose 2 h before the cessation of the tirofiban infusion. Cases of intracranial hemorrhage or thromboembolism were recorded. Results This study included a total of 105 patients with ruptured intracranial aneurysms, who underwent stent-assisted coiling. In terms of clinical severity, a presenting Hunt–Hess clinical-grade I was observed in 47 (44.8%) cases, grade II in 19 (18.1%) cases, grade III in 30 (28.6%) cases, grade IV in 6 (5.6%) cases, and grade V in 3 (2.9%) cases. None of the patients showed a newly developed tirofiban-related intracerebral hemorrhage, intraventricular hemorrhage, subarachnoid hemorrhage, or ventriculostomy-related hemorrhage. There were 3 (2.8%) patients who had thromboembolic complications. Conclusions We have determined a new protocol for prophylactic intraoperative tirofiban during the endovascular treatment of ruptured intracranial aneurysms with no oral antiplatelet medications. In our study, tirofiban showed a low risk of hemorrhagic or thromboembolic complications. Tirofiban appears to be a safe and alternative during the stent-assisted coiling of ruptured intracranial aneurysms.
