摘要
部分脑干腔隙性梗塞(腔梗)患者,因无定位体征而常常被误诊为椎基底动脉供血不足(V-BAI)。为了对这些患者作出早期诊断,以利治疗及对预后的估计,对21例无定位体征的脑干腔梗组(A组)与30例V-BAI(B组)患者的临床表现、CT、MRI、经颅多普勒超声(TCD)及脑干听觉诱发电位(BAEP)进行比较分析。结果表明:A组以持续症状为主,治疗效果较差,其TCD改变不如B组明显,而BAEP的Ⅲ、Ⅴ波峰潜伏期(PL)及Ⅲ~Ⅴ波峰间潜伏期(IPL)延长比B组明显。结论:凡症状持续、疗效较差、TCD改变不显著而BAEP示听神经中枢段障碍明显者,要高度怀疑脑干腔梗。MRI是脑干腔梗可靠而敏感的检查手段。
