背景:最近证明大血管闭塞的急性缺血性卒中血管内治疗是有效的。研究者旨在开发一个有助于医院早期处理,能够预测大血管闭塞适合血管内治疗的分数。

设计:回顾性队列研究。

设置:两个三级瑞士卒中中心。

患者:连续性急性缺血性脑卒中患者(1645例;急性卒中登记和洛桑注册表分析),在症状开始6和12小时进行CT血管造影,根据闭塞部位将其分类。对人口统计学和临床信息进行Logistic回归分析,确定大血管闭塞(定义为颅内颈内动脉、基底动脉、大脑中动脉M1段闭塞)的预测因子。基于Logistic回归系数,创建并进行内部(848例,伯尔尼卒中注册)和外部验证。

干预:没有。

测量和主要结果:在推导队列中,大血管闭塞316例(21%);和在外部验证队列中566(28%)例。五个预测因子增加到预测分数中:NHISS,半侧忽略、女性、心房纤颤、无卒中史及卒中前残疾(改良Rankin量表评分<2)。在内部和外部验证队列中的诊断准确率是良好(接受者工作特征曲线下面积,0.84)。就预测误差(Wilcoxon符号秩检验,P<0.001)和推导队列和总队列中区分效力(ROC曲线下面积,0.81和0.80,DeLong检验,P = 0.02)。来说,预测分数略好于NHISS。

结论:研究者的预测分数能够准确预测大血管闭塞适合血管内治疗的患者。与NHISS分数相比,增加入院人口学和病史有助于提供最小的增量预测值。
