Objective To explore the safety and efficacy of endovascular therapy dominated by balloon dilation rather than traditional stent thrombectomy.To analyze the independent influencing factors that lead to poor prognosis in patients with mechanical thrombectomy.Methods The clinical data of 79 patients with acute anterior circulation intracranial atherosclerotic large vessel occlusion(ICAS-LVO)admitted to The Third Hospital of Shanxi Medical University from January 2021 to July 2022 were analyzed retrospectively.According to different dominant opening methods,it was divided into balloon dilation group(34 cases)and stent thrombectomy group(45 cases).The risk factors affecting the prognosis of mechanical thrombectomy were explored by univariate and multivariate Logistic regression analysis.Results The overall vascular recanalization rate was 88.6％(70/79),and there was no significant difference in the proportion of recanalization between the groups(P＞0.05).The proportion of balloon dilation in the stent dominant group was 51.1％(23/45).The proportion of M1 occlusion in the stent dominant group was higher than that in the balloon dilation group(P＜0.05).The National Institute of Health Stroke Scale(NIHSS)score was lower than that in the stent thrombectomy group after 2 weeks of recanalization in the bulbous expansion group(P＜0.05).There were no significant differences in the proportion of 90-d functional independence,symptomatic intracranial hemorrhage rate and 90-day mortality rate between the two groups(all P＞0.05).There were no significant differences in gender,smoking history,hypertension,hyperlipidemia,diabetes,preoperative intravenous thrombolysis,and stenting between the two groups(all P＞0.05).There were no significant differences in age,admission NIHSS score,admission Alberta Stroke Program Early Computer Tomography Score(ASPECTS),and puncture-to-recanalization time between the two groups(all P＞0.05).High NIHSS score on admission(odds ratio=1.119,95％confidence interval=1.020-1.226,P:0.017)were independent risk factors for poor prognosis for mechanical thrombectomy.Conclusions For patients with acute anterior circulation ICAS-LVO,balloon dilation-led endovascular therapy is safe and effective.High NIHSS scores increase the risk of adverse outcomes after embolectomy.
