| 摘 要： | 目的观察局灶性及弥漫性颅高压（ICH）对大脑中动脉（MCA）、基底动脉（BA）、颈内动脉颅外段（ESICA）血流动力学的不同影响，探讨经颅多普勒（TCD）对颅内压的评估价值。方法对118例颅高压患者进行187次腰穿测颅内压（ICP）前行TCD检查，对TCD资料及脑脊液压力进行分析，并与对照组比较。结果随ICP升高，TCD检测血管MCA、BA、ESICA均表现出高阻力血流频谱，脉动指数（PI）增大。ICP与ESICA的平均血流速度（Vm）相关性最大（r=-0．314，P=0．000），与MCA的PI相关性最大（r=0．758，P=0．000）。局灶性颅高压Vm病侧慢于健侧，PI高于健侧，弥漫性颅高压双侧Vm、PI无显著差异。结论评估局灶性颅高压应检测病变侧MCA，弥漫性颅高压检测双侧MCA均可，在双侧颞窗透声不好时可检测ESICA。 |

| Abstract: | Objective To observe the effects of local and diffuse intracranial hypertension on hemodynamics of middle cerebral artery (MCA),base artery (BA) and extracranial segments of the internal carotid artery (ESICA) and to study the predictive value of transcranial Doppler (TCD) in intracranial pressure (ICP). Methods TCD examination was taken before 187 times of lumbar puncture for pressure testing in 118 patients with intracranial hypertension.Results With progressive increase of ICP,TCD showed high resistance ... |
