摘要
目的探讨深部脑白质高信号(DWMHs)对轻型缺血性脑卒中(IS)的诊断效能,同时观察假性脑卒中(SM)的特点。方法连续收集2018年1-3月在青岛西海岸新区人民医院神经内科住院的患者110例,分为SM组(43例)和轻型IS组(67例)。绘制受试者操作特征(ROC)曲线,计算曲线下面积,比较DWMHs对2组疾病的诊断效能。结果 SM组中,DWMHs评分2~3分患者5例,其中1例为代谢性脑病,4例为癫痫发作后的Todd′s麻痹。轻型IS组中,DWMHs评分2~3分患者60例。ROC曲线下面积为0.918(95%可信区间:0.860~0.976),标准误为0.030,差异有统计学意义(P<0.01)。结论 DWMHs评分针对轻型IS有较高的诊断效能,SM最常见的病因包括中毒或代谢性脑病、癫痫发作后的Todd′s麻痹及偏头痛或周围性眩晕等。
