Therapeutic Efficacy of Tirofiban Combined With Thrombus Aspiration and Stent Thrombectomy in the Treatment of Large Vessel Occlusion Ischemic Stroke

OBJECTIVE: This research aimed to ascertain the effects of tirofiban combined with thrombus aspiration and stent thrombectomy on large vessel occlusion ischemic stroke (LVO-IS). METHODS: Sixty patients with acute ischemic stroke (AIS) caused by LVO were randomized into the control group and the intervention group (n=30). Patients in the control group received thrombus aspiration combined with stent thrombectomy, while those in the intervention group were treated with tirofiban combined with thrombus aspiration and stent thrombectomy. General data, perioperative-related indicators, cerebral blood flow perfusion, coagulation function indicators, and neurological function indicators were collected, and the prognosis was observed after 3-month treatment. RESULTS: A comparison of symptomatic cerebral hemorrhage rate and hospital mortality rate between the 2 groups displayed no significant difference ( P >0.05). The rate of revascularization in the intervention group (90.00%) was higher versus the control group (66.67%). After treatment, the mean blood flow and cerebral blood volume of the intervention group were higher and the time to peak cerebral blood flow was less versus the control group. The prothrombin time, activated partial thromboplastin time, and prothrombinogen time of the intervention group were higher, and fibrinogen was lower versus the control group. A lower National Institutes of Health Stroke Scale score was observed in the intervention group versus the control group. CONCLUSIONS: Tirofiban combined with thrombus aspiration and stent thrombectomy has good efficacy in LVO-IS patients.
