摘　　要：目的利用经颅多普勒超声(TCD)检测脑鸣患者的脑血流情况,并对相关情况进行分析、总结。方法用TCD仪对153例脑鸣患者颅内主要动脉进行检测。结果 153例脑鸣患者中,122例检测出有血流动力学改变,占79.7%,其中血流速度增快70例(57.4%),血流速度减慢45例(36.9%),血流速度增快患者明显高于血流速度减慢者(χ2=8.966,P=0.003),狭窄7例(5.7%)。前循环血流动力学改变35例(28.7%),后循环45例(36.9%),前后循环均改变42例(34.4%),前后循环血流动力学改变的发生率无明显差异(χ2=3.507,P=0.61)。结论脑鸣患者普遍存在血流动力学改变,甚至有脑动脉狭窄发生,TCD对脑鸣患者的病因诊断有重要的辅助作用,应作为常规检查。Objective To detect cerebral blood flow dynamics and evaluate its character. Methods A total of153 tinnitus cerebri patients examined with transcranial Doppler ultrasonography（TCD）. Results Hemodynamics alteration was found in 122 out of 153 patients（79.7%）, blood flow velocity step up（57.4%） was significantly higher than blood flow velocity step down（36.9%）（ χ2=8.966, P=0.003）. The cerebral blood flow dynamics change between anterior circle and vanterior circle was not significant（ χ2=3.507, P=0.61）. Conclusions Hemodynamics alteration was found in tinnitus cerebri patients. TCD should be performed in these patients routinely.
