摘　　要：目的 研究经颅多普勒(TCD)在单侧颈动脉阻断试验(CAO)中应用的价值。方法 对32例可能需要临时或永久阻断颈动脉的患者进行前瞻性TBO-TCD-SP(残端压)研究。结果 有症状组和无症状组的大脑中动脉平均血流速度下降率(△mV％)有明显差异(P<0.05),同时△mV%和△SP%相关性显著(P<0.01)。结论 TCD结合TBO在CAO后脑对缺血耐受性预测中较为可靠。Objective In order to invetigate the difference in the detection between symptomatic and asymptomatic patients with unilateral carotid artery occlusion transcranial doppler ultrasound. Methods Thirty - two patients underwent TBO - TCD - SP invetigation. Results The △mV% in symptomatic group was obvious lower than that of in asymptomatic group (P <0. 05) , and the coefficient of correlation between △mV% and △SP% was 0. 81 (P <0. 01 ) . Conclusion TCD - TBO is reliable in the prediction of ischemic occlusion of the unilateral carotid artery.
