椎基底动脉供血不足患者脑干功能损害与经颅多普勒检测的相关性

目的探讨椎基底动脉供血不足(VBI)患者脑干功能与经颅多普勒(TCD)检测的相关性。方法对68例临床诊断(VBI)的患者进行瞬目反射(BR)、脑干听觉诱发电位(BAEP)和TCD检测。结果VBI组脑干功能损害84.6%,TCD异常率为83.1%,χ2检验差异无显著意义;非VBI组脑干功能损害8.3%,TCD异常率为46.6%,χ2检验差异有显著意义。VBI组脑干功能损害及TCD异常者为98/136,皆正常者为24/136,两者占89.7%;非VBI皆异常者为4/60,皆正常者为32/60,两者占60%。结论根据临床表现,结合BR、BAEP及TCD检查结果可提高对VBI的诊断价值,而单独的TCD结果不足以作为诊断依据。

The correlation of brainstem function injuries and transcranial Doppler on the vertebrobasilar ischemia

Objective To investigate the correlation of br ainstem function injuries and transcranial Doppler(TCD)examination on the vertebrobasilar ischemia(VBI ).Methods 68patients with VBI and 30patients with non-VBI were studied by blink reflex(BR),brainstem au-ditory evoked potentials(BAEP)and TCD .Results It showed that the incidence of brain stem function injuries in VBI group was 84.6%,TCD83.1%,there being no significant di fference by Chi-square test,while i n non-VBI group brainstem function i njuries 8.3%,TCD 46.6%.Both brainstem function injuries and TCD were abnormal in VBI 98/136,non-VBI 5/60and normal VBI 24/136and non-VBI 32/60.Conclusions It indicates that BR,BAEP combined with TCD and clinical signs can make th e diagnosis of VBI.The results of TCD alone can not be a considerable diagnostic basis for VBI.
