椎基底动脉血流参数的测定及意义

The Parametric Measurement of Blood Flow of Vertebral Artery and Basilar Artery and Its Significance

目的：探讨TCD在测定椎基底动脉血流参数中的作用以及做为颈部推拿前筛选适应证的价值。方法：对临床眩晕、颈椎病患者及查钵和年青对照组进行对比研究。结果：眩晕和颈椎病患者右侧推动脉的血流速度。搏动指数等与对照组差异显著（P＜0.05）。结论；右侧椎动脉较左侧推动脉易发生动脉硬化等病变，对眩晕和颈椎病患者要慎用左旋推扳手法。TCD在颈部推拿前筛选合适的病例有较大的帮助。

To provide a basis of the Transcranial Doppler(TCD) on the parametric measurement of blood flow of vertebral artery and basilar artery and its clinical value for screening the patients of cervical manipulations. The parameters were compared with the different groups. The results showed that some parameter had obviously change in the patients of vertigo and cervical spondylosis. The phenomenon suggested that right vertebral artery has more disorders (such as atheroscleorsis ) than that of left vertebral artery. The rotatory manipulation to left should be avoided in the patients of vertigo and cervical spondylosis. TCD may be help for screening the patients of cervical manipulations
