摘要 目的探讨经颅多普勒血流图(TCD)在颅内动脉狭窄诊断中的价值。方法对60例疑有颅内动脉狭窄的患者应用TCD测量各条血管的血流参数,包括收缩峰值流速、舒张末流速、平均流速、阻力指数,并与数字减影血管照影(DSA)结果进行对比分析。结果32例TCD诊断颅内动脉狭窄,28例经DSA证实。TCD诊断颅内动脉狭窄的特征是频谱多普勒显示狭窄处血流速度异常增高,频谱形态呈湍流、涡流,同时音频信号响亮。狭窄严重者血流速度不增快或者明显减低。结论TCD对颅内动脉狭窄具有一定的诊断价值,可作为早期筛选性诊断方法。 Objective To investigate the value of the transcranial Doppler(TCD)in dragnosing the cerebral artery stenorsis.Methods 60 patiets who had been highly suspected cerebral arterial stenosis were detected by TCD.The shape and courser of every cerebral artery were observed.Hemodynamic oarameters such as systole peak velocity,diastole end velocity,meanvelocity and resistance index were measured.All results were compared with digital subtract angiography(DSA).Results 32 patinents were diagnosed cerebral arterial stenosis by TCD.28 of 32 cases confirmed by DSA.The velocity of the foci increased abnormally.The frequency soectrum of the setnotic vascular showed turbulence,meanwhile noise accompanied.The velocity of the foci was not increased or decreased obvioously.Conclusion TCD is of value in diagnosing the cerebral artery stenosis and can be considered as a diagnostic method of early screening.
