- Abstract: Objective To compare the clinical efficacy between a direct aspiration first-pass technique(ADAPT)and stent-retriever thrombectomy(SRT)in the treatment for acute ischemic stroke(AIS)caused by intracranial atherosclerotic stenosis related large vessel occlusion(ICAS-LVO).Methods We retrospectively included patients with AIS caused by ICAS-LVO who received endovascular treatment in The First Affiliated Hospital of Xi'an Jiaotong University or The Second Affiliated Hospital of Shaanxi University of Chinese Medicine between January 2020 and January 2023.They were divided into ADAPT group and SRT group according to the first-selected device for thrombectomy.We compared the baseline data,test and examination results,operation process,clinical prognosis and follow-up data of the two groups.Results A total of 117 patients were recruited,including 48 patients in the ADAPT group and 69 patients in the SRT group.There was no significant difference in the baseline data between the two groups.The success rate of both the first-time thrombectomy(P=0.014)and the first-selected device of thrombectomy(P＜0.001)was significantly higher in the SRT group than in the ADAPT group.Meanwhile,the incidence of iatrogenic dissection(P＜0.001)and vasospasm(P=0.003)was significantly lower in the SRT group than in the ADAPT group.The proportion of patients for whom the device of thrombectomy was changed for remedial treatment in the ADAPT group was significantly higher than that in the SRT group(P＜0.001).However,the two groups did not differ significantly in the rate of successful vascular recanalization,incidence of symptomatic/asymptomatic intracranial hemorrhage or the rate of 90-day favorable prognosis.Conclusion For patients with AIS caused by ICAS-LVO of MCA,SRT has a higher rate of immediate successful vascular recanalization with a lower rate of secondary vascular injury compared with ADAPT,but the two techniques have similar efficacy on the 90-day prognosis.
