Safety and efficacy of intravenous Tirofiban infusion after mechanical thrombectomy in acute ischemic stroke: a retrospective observational study.

Objective To investigate the safety and efficacy of intravenous Tirofiban infusion after mechanical thrombectomy in patients with acute ischemic stroke. Methods A consecutive series of patients with acute ischemic stroke who underwent mechanical thrombectomy were included. The patients were categorized into two groups according to whether they received intravenous Tirofiban infusion after mechanical thrombectomy. Intracranial hemorrhage (ICH) and all-cause mortality were studied as safety outcomes; recanalization of target vessel evaluated by thrombolysis in cerebral infarct (TICI) scale, and neurological improvement evaluated by Institutes of Health Stroke Scale (NIHSS) and modified Rankin scale (mRS) were studied as efficacy outcomes. Results A total of 31 patients who underwent mechanical thrombectomy were enrolled, among which 8 (25.81%) received a standard dose of intravenous Tirofiban infusion after mechanical thrombectomy. There was no significant difference in baseline characteristics between the two groups (all P>0.05). None (0.00%) of the patients suffered ICH in the Tirofiban group, while 3 (13.04%) suffered ICH in the control group (P=0.550); similar all-cause mortality rates were found in both groups (25.00% versus 17.39%, P=0.634). In the Tirofiban group, all patients achieved successful recanalization defined by TICI groups (25.00% versus 17.39%, P=0.634). In the und in both groups (25.00% versus 17.39%, P=0.634). In th4). In thle, and neurological improvement evaluated so, 'et al' is notned by 3-month mRS≤2, which were not statistically significant when compared to the control group (all P>0.05). Conclusion Intravenous Tirofiban infusion after mechanical thrombectomy is safe and effective in patients with acute ischemic stroke.
