常见脑病中医辨证分型与经颅多普勒检测结果间关系的探讨

APPOROACH THE RELATIONSHIP BETWEEN THE DIFFERENTIAION OF SYNDROME AND CLASSIFICATION OF COMMON ENCEPHALOPATHY AND THE DETERMINATION RESULTS BY TCD

本文旨在探讨常见脑病中医辨证分型与经颅多普勒(TCD)检测结果之间的关系,对261例脑病患者进行了TCD检测及中医辨证分析。结果表明:脑动脉血流信号消失、收缩期血流速度低于正常、脑动脉硬化等TCD频谱图像,多为气虚血瘀型或气虚痰阻型脑病,而颈内动脉血流信号缺如、颈内动脉血流速度减慢多见于气虚血瘀型,推基底动脉血流速度减慢多见于气虚痰阻型;脑血管收缩期高流速信号,多属肝肾阴亏风阳上扰,中脏腑风阳痰热内闭中风;脑动脉硬化兼狭窄的多普勒图像,多见于肾精亏损兼瘀血型脑病。并从中医病机角度探讨了常见脑病出现TCD检测结果的机理。

In order to approach the relationship between the differentiation of syndrome and classification of common encephalopathy and determination results by TCD. 216 cases with encephalopathy were determined and analyzed accoording to differentiation and classification. Results showed that the TCD frequency spectrum such as disappearance of cerebral arteries bood flow signal, velocity of bood flow geting lower than normal in systole and cerebral arteriosclersis all be longed to deficiency of Qi and stasis of blood or deficiency of qi and obstruction of phlegm, but disappearance of internal carotid arteries. velocity of blood flow getting slow belonged to deficiency of Qi and stasis of blood, velocity of blood flow in vertebrobasilar getting slow common - seen deficiency of Qi and obstruction of phlegm; higher velocity of blood flow in systole belonged to deficiency of yin of liver and kidney, sthenia of liver - yang cerebral arteriosclersis accopanied by sticture belonged to deficiency of kidney essence and stasis of blood. All these indicated that there was close relation ship between the differentiation of syndrome and classification of common encephalopaty in TCM and the determination results by TCD.
