摘　　要：目的探讨椎动脉经颅多普勒(TCD)、磁共振动脉造影(MRA)、脑干诱发电位(BAEP)及椎动脉超声对椎动脉狭窄或变异的诊断价值。方法对89例椎基底动脉缺血患者进行椎动脉TCD、MRA、BAEP及椎动脉超声等检查。结果89例患者中椎动脉TCD异常74例(83.15%),MRA异常47例(52.81%),椎动脉B超异常46例(51.69%),BAEP异常40例(44.94%)。椎动脉TCD可清晰地反映血管的血流速度和方向,间接地反映血管狭窄,椎动脉MRA能清楚地显示血管病理形态,TCD异常率与动脉硬化和颈椎病有关,MRA的异常率与患者的病程长短有关。结论椎动脉TCD、MRA、BAEP及椎动脉超声4种方法合用,有助于全面客观地诊断椎动脉狭窄或变异。Objective To study the diagnostic value of transcranial TCD,MRA,BAEP and vertebral artery duplex uhrasonography in vertebral artery stenosis or variation. Methods 89 patients were examined by TCD, MRA, BAEP and duplex ultrasonography of the same vessels. Results In 89 cases, the abnormal rate with TCD, MRA, TCD and BAEP was 83.15%, 52.81%, 51.69%, 44.94% respectively. Vertebral artery TCD could reflect blood flow velocity and direction clearly, and indirectly reflect vascular stenosis. MRA could clearly display vascular pathologic morphology. The abnormal rate of TCD was associated with arteriosclerosis and cervical spondylosis, and the abnormal rate of MRA was correlated with course of disease. Conclusions The combination of MRA, TCD, BAEP and duplex ultrasonography of vertebral artery is helpful for diagnosis of vertebral artery stenosis or variation.
