Study on Morphological Pathological Mechanism of Vertebral Basilar Artery of Deficiency of the Upper Causing Dizziness Theory

Objective: In order to discuss the morphological pathological mechanism of the vertebral basilar artery of the Deficiency of the Upper Causing Dizziness,and try to prove the correlation between the morphological pathological changes of vertebral basilar artery and the Deficiency of the Upper Causing Dizziness Theory.Method:In 60 cases of vertigo patients who were identified as Deficiency of the Upper(Insufficient blood supply of vertebral artery),34 cases were male and 26 female;aged from 28~85,average 50.73 years old;the course of disease was from 2 weeks to more than 10 years.First of all,we will use Transcranial Doppler(TCD) to confirm that the vertigo is caused by insufficient blood supply of vertebral artery.Secondly,we will use a three dimensional computed topographic angiography(3D-CTA) to test the morphological pathological changes of the vertebral basilar artery,researching the morphological pathological mechanism of the vertebral basilar artery of the Deficiency of the Upper Causing Dizziness.Results: Among 120 vertebral basilar arteries of 60 cases,there are 60(71.1%) vertebral arteries,82(50.0%) basilar arteries and 60(50%) posterior inferior cerebellar arteries have changes of the blood flow.There are 71(59.2%) vertebral basilar arteries have vascular morphological changes of segment V1,37(30.8%) vertebral basilar arteries have vascular morphological changes of segment V2,and 102(85.0%) vertebral basilar arteries have vascular morphological changes of segment V4.Conclusion: the morphological pathological mechanism changes of the vertebral basilar artery→changes of the blood flow→insufficient blood supply of the vertebral artery→insufficient blood supply of the cerebella is the mechanism of the vertigo.And it was basically consistent to the traditional Chinese medicine theory of Deficiency of the Upper Causing Dizziness.
