目的探讨经颅多普勒超声(TCD)对椎-基底动脉供血不足患者的诊断价值。方法使用北京鑫悦奇JYQTCD-2000经颅多普勒(TCD)诊断仪，用2MHz脉冲多普勒探头检测颅内动脉。患者坐位略低头，探头经枕骨大孔分别探测左、右椎动脉(LVA，RVA)，基底动脉(BA)。选择频谱的最高图像，观察图形排除干扰,分析其收缩峰的最高流速Vp，平均流速Vm，脉动指数PI值等。结果120例患者的检测结果中，异常94例，占总人数78.3%，表现为椎-基底动脉血流速度增快的35例，占29.2%，表现为椎基底动脉血流速度减慢的59例，占49.16%，当椎-基底动脉硬化伴狭窄时可出现收缩期高流速的多普勒频谱或出现涡流的多普勒信号。 TCD的检测结果异常以椎动脉为多见，其次为基底动脉。结论 TCD具有准确、安全、无创伤、可重复性好等特点，对判断脑缺血程度、确定病变血管及病因的诊断均有重要价值，为理想的非创伤性诊断椎基底动脉供血不足的方法。
目的探討經顱多普勒超聲(TCD)對椎-基底動脈供血不足患者的診斷價值。方法使用北京鑫悅奇JYQTCD-2000經顱多普勒(TCD)診斷儀，用2MHz脈遲多普勒探頭檢測顱內動脈。患者坐位略低頭，探頭經枕骨大孔分彆探測左、右椎動脈(LVA，RVA)，基底動脈(BA)。選擇頻譜的最高圖像，觀察圖形排除榦擾,分析其收縮峰的最高流速Vp，平均流速Vm，脈動指數PI值等。結果120例患者的檢測結果中，異常94例，佔總人數78.3%，錶現為椎-基底動脈血流速度增快的35例，佔29.2%，錶現為椎基底動脈血流速度減慢的59例，佔49.16%，噹椎-基底動脈硬化伴狹窄時可齣現收縮期高流速的多普勒頻譜或齣現渦流的多普勒信號。 TCD的檢測結果異常以椎動脈為多見，其次為基底動脈。結論 TCD具有準確、安全、無創傷、可重複性好等特點，對判斷腦缺血程度、確定病變血管及病因的診斷均有重要價值，為理想的非創傷性診斷椎基底動脈供血不足的方法。

Objective To explore the value of transcranial Doppler (TCD) in patients with the diagnosis of vertebrobasilar insuf iciency. Methods Beijing Xin Qi JYQTCD-2000 method using transcranial Doppler (TCD) diagnostic instrument, Doppler probe detection of intracranial artery with 2MHz pulse. Patient seat slightly down, probe through the foramen magnum respectively detection of left and right vertebral artery (LVA, RVA) and basilar artery (BA). The highest image selection of spectrum, observing the graph to eliminate interference, analysis of the peak systolic maximum velocity Vp, average velocity Vm, pulsatility index Pivalue. Results The 120 patients in the test result, abnormal 94 cases, accounting for 78.3% of the total number, for vertebral basilar artery blood flow velocity slowed down, spectral anomalies when vertebrobasilar arterial sclerosis and stenosis can occur when high flow velocity systolic Doppler spectrum or the appearance of Doppler signal of eddy cur ent. The TCD results abnormality of vertebral artery was more common, fol owed by basal artery. Conclusion TCD is an accurate, safe, non-invasive, reproducible, and to determine the extent of cerebral ischemia in determining the diagnosis has important value of vascular lesions and the etiology, a method for the diagnosis of vertebrobasilar insuf iciency of non-traumatic ideal.
