AbstractObjectiveMethodsResultsConclusionTo analyze the effectiveness of stent retriever mechanical thrombectomy combined with tirofiban in treating acute ischemic stroke.Markedly effective is defined as an SIS score of over 90, effective is indicated by an SIS score of between 50–90, and a score of below 50 suggests ineffective treatment results.①The treatment’s overall effectiveness in the observation group (91.30%) was significantly higher than that in the control group (75.56%) (p < 0.05). ②The vascular recanalization rate in the observation group (89.13%) was significantly higher than that in the control group (71.11%) (p < 0.05). ③The stent retrieval operation count (2.41 ± 0.23) was significantly lower in the observation group than in the control group (1.29 ± 0.16) (p < 0.05). ④ After treatment, the platelet aggregation rate (10.74 ± 3.95) and NIHSS scores (6.58 ± 1.04) were significantly lower, and the Barthel index (77.86 ± 7.21) was significantly higher in the observation group compared to the control group (26.47 ± 5.12, 7.75 ± 2.36, 68.12 ± 6.15) (p < 0.05). All platelet aggregation rate, NIHSS scores and Barthel Index showed significant improvement after treatment when compared to those before treatment (p < 0.05).The combined application of stent retriever mechanical thrombectomy and tirofiban in acute ischemic stroke treatment shows promising effectiveness. Compared to stent retriever alone, tirofiban adjunctive therapy enhances vascular recanalization, reduces retrieval procedures, shortens treatment duration, inhibits platelet aggregation, and improves neurological function recovery, daily living activities, and prognosis. Moreover, it doesn’t significantly increase symptom-related risks. [ABSTRACT FROM AUTHOR]
