“髓海不足”与椎动脉供血不足的相关性研究

The Relevance Research of “Sui-hai Deficiency” with Vertebral Artery Caused by Less Blood Provision

[目的]探讨“髓海不足”与椎动脉供血不足及形态学改变的相关性。[方法]选择符合椎动脉型颈椎病诊断标准的病例84例为实验观察对象,采用3D—CTA技术检查椎动脉形态学改变,结合TCD检测椎动脉血流速变化,研究“髓海不足”眩晕的发病机理。[结果]84例168例支椎动脉,低流速(Vm<20cm/s)占47.62%;高流速(Vm>40cm/s)占18.45%。异常率为66.07%。有椎动脉形态学改变的126支,异常率为75%。在形态学改变的椎动脉中,低流速改变占63.50%,高流速改变占24.60%,异常率为88.10%,[结论]椎动脉形态学改变是导致椎动脉供血不足的直接原因。椎动脉形态学改变→血流速异常→椎动脉供血不足→“髓海不足”→眩晕,是眩晕发病的根本原因。

[Objective] To study the relevance between ＂Sui-hai deficiency＂ and classification vertebral artery caused by less blood provide with morphological changes. [Method] 84 cases accord with the diagnosis standard of vertebral artery, all these patients were tested morphological changes by a three dimensional computed topographic anglograpy（3D-CTA）, and then measured by transeranial Doppler（TCD） to test the changes of blood, research mechanism of ＂Sui-hai deficient＂ vertigo. [Results]168 vertebral arteries of 84 cases in this group, low flow speed （Vm〈20cm/s） was 47.62% ;high flow speed （Vm〉40cm/s） was18.45% ,and the abnormal rate was 66.07%. 126 vertebral arteries morphological abnormal rate was 75%. Changes of low flow speed was 63.50 M, high flow speed was 24.60 %, the abnormal rate was 88.10 %. [Conclusion] Morphology of vertebral arties changes is the direct reason to make the defflciency of vertebral artery. Morphological changes → blood flow abnormal → vertebral artery with less blood provide → ＂Su-hai deficient＂→ vertigo, which is the major cause of vertigo.
