文摘目的比较直接抽吸技术(a direct aspiration first-pass thrombectomy,ADAPT)和支架取栓(stent retriever thrombectomy,SR)对急性基底动脉闭塞(acute basilar artery occlusion,ABAO)患者的预后及认知的影响。方法前瞻性纳入神经内科2019年8月-2022年12月间诊断为ABAO患者共90例。根据机械取栓治疗的类型,将患者分为ADAPT组(44例)和SR组(46例)。比较两组患者一般临床资料、手术相关指标、临床预后、不良事件及认知功能。预后评估利用7 d NIHSS评分和90 d mRS评分;认知功能评估利用卒中后6个月MoCA评分;安全性评估利用不良事件发生率和死亡率。采用单因素分析及多因素Logistic回归模型分析影响ABAO患者发生不良临床预后和卒中后认知障碍(poststroke cognitive impairment,PSCI)的独立危险因素。结果ADAPT组与SR组患者间的血管成功再通率、术后7 d NIHSS评分、90 d良好结局率(mRS评分≤2分)、6个月后PSCI发生率、不良事件发生率比较,差异均无统计学意义(均P>0.05)。但较SR组,ADAPT组患者的血管再通尝试次数更少,穿刺至血管开通时间和发病至血管再通时间更短(均P<0.05)。多因素Logistic回归分析显示,糖尿病史(OR=18.922,95%CI:2.787~128.474;P=0.003)、基线高NIHSS评分(OR=1.195,95%CI:1.088~1.316;P=0.000)和低pc-ASPECTS评分(OR=0.298,95%CI:0.154~0.576;P=0.000)是ABAO患者临床预后不良的独立危险因素。高龄(OR=1.150,95%CI:1.034~1.279;P=0.010)、较长的发病至血管再通时间(OR=1.006,95%CI:1.000~1.012;P=0.035)、基线高NIHSS评分(OR=1.120,95%CI:1.039~1.208;P=0.003)和低pcASPECTS评分(OR=0.571,95%CI:0.355~0.918;P=0.021)是ABAO患者发生PSCI的独立危险因素。结论与SR技术对比,ABAO患者行ADAPT治疗具有相同的临床疗效和安全性,但是行ADAPT可减少再通尝试次数,获得更短的血管开通时间。糖尿病、基线高NIHSS评分和低pc-ASPECTS评分与ABAO患者不良的临床预后独立相关。高龄、较长的发病至血管再通时间、基线高NIHSS评分和低pc-ASPECTS评分与ABAO患者PSCI的发生独立相关。
