The Relevance Research of “Sui-hai Deficiency” with Vertebral Artery Caused by Less Blood Provision / 浙江中医药大学学报

ABSTRACT

[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 angiograpy(3D-CTA),and then measured by transcranial 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(Vm40cm/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%,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 defficiency 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.
