文摘目的探讨影响急性后循环缺血性卒中(PCIS)患者血管内治疗(EVT)的预后因素。方法回顾性收集2020年1月至2023年8月在中国人民解放军联勤保障部队第九六〇医院行EVT的71例急性PCIS患者的病例资料。术后90 d根据改良Rankin量表(mRS)评分分为预后良好组43例(mRS评分≤2分)和预后不良组28例(mRS评分>2分),比较两组患者的年龄、性别、高血压及糖尿病等一般情况,以及血尿酸(BUA)、血肌酐(Scr)及血尿素氮(BUN)等临床资料。结果共纳入71例发病24 h内入院接受EVT的急性PCIS患者,其中预后良好组43例,预后不良组28例。两组患者在性别、年龄、BUA、总胆固醇(TC)、甘油三酯(TG)、低密度脂蛋白胆固醇(LDL-C)、是否有高血压、糖尿病、冠心病、是否吸烟及饮酒等方面比较,差异无统计学意义(P>0.05);单因素分析提示,预后不良组患者的Scr、BUN、术前美国国立卫生研究院卒中量表(NIHSS)评分及14 d NIHSS评分均高于预后良好组,差异有统计学意义(P<0.05)。经多元logistic回归显示,Scr(OR=3.414,P=0.041)、BUN(OR=4.265,P=0.035)是影响急性PCIS患者EVT治疗效果的独立危险因素。所有患者均未发生颅内出血及死亡。结论急性PCIS患者EVT后能部分获益,Scr及BUN升高是影响急性PCIS患者EVT后预后不良的独立危险因素。
