【摘要】 目的 观察弥漫性颅内高压患者的TCD频谱和参数改变。 方法 对66例弥漫性颅高压患者进行TCD检测，同时测血压并腰穿测颅内压。 结果 颅内压升高时，出现典型的TCD频谱:高阻力血流频谱、舒张期血流消失频谱。随着颅内压升高，舒张末期血流速度减慢，血管脉动指数及阻力指数增大。 结论 根据特征性TCD频谱和TCD参数改变可间接推断颅内压变化。

    【Abstract】 Objective To observe the changes of transcranial Doppler flow patterns and parameters in diffuse in-tracranial hypertension.Methods 66patients with intracranial hypertension caused by diffuse cephalitis meningica were observed whose blood flow velocity was measured with transcranial Doppler and intracranial pressure，arterial pressure were measured at the same time.Results With progressive increase of intracranial pressure characteristic flow patterns were observed:high resistance pattern，pattern of diastolic flow disappear.With progressive increase in intracranial pressure ......
