经颅多普勒在病毒性脑炎的应用研究

目的　观察病毒性脑炎脑血流动力学变化特点 ,探讨TCD检测在判断其病情严重程度和临床预后的应用价值。方法　TCD检测 2 2例患者并与 30例正常人对照 ;对病情及预后比较。结果　病毒性脑炎病人与正常人相比ACA血流速度增快 ;MCA流速减慢 ;ACA ,MCA ,VA的PI值均显著升高。MCA Vs与GCS成负相关 ,与GOS无相关关系。结论　病毒性脑炎脑血流动力学异常改变以颈内动脉系统为主 ;MCA Vs高流速与病情严重程度密切相关 ;TCD检测结果与预后无显著相关关系

Application of TCD for the viral encephalitis

Objective To observe the effects of viral encephalitis on cerebral blood dynamics, we discuss the value of applying TCD for estimating the severity degree and clinical prognose of VE. Methods 22 VE patients and 30 normal collators were examined. patients by classifying them by the prognoses valued and former consciousness valued. Results ACA velocities increased, MCA velocities slowered. PI values of ACA, MCA, VA all remarkably increased. MCA Vs correlated GCS subtractively and had no correlation with GOS. Conclusion The TCD abnormity of VE occurs mainly in intracervical artery system. The high systolic velocities of MCA in VE patients nearly correlated the severity degrees. But TCD results can't apply for estimating the prognoses.
