Objective:
To observe the morphological structure and hemodynamic changes of the vertebral artery in cervical spondylosis by high frequency color duplex sonography.
Methods:
We measured 138 cases of cervical spondylosis at the vertebral artery with a 7.5-10 MHz probe of high frequency color duplex sonography, to determine morphological changes, Diameter(D), Velocity(V), Blood flow volume, and Resistance index(RI) and (PI). A controlled analysis was performed at the same time.
Results:
The measurement showed that the vertebral arteries of the patients bent more severely than the controlled group. There was a significant difference between the two groups (P < 0.01) in Diameter (D), Velocity (except mean velocity), Blood flow volume, and resistance index (RI) and (PI).
Conclusion:
High frequency color duplex sonography has provided clinical judement on morphological and blood flow dynamic parameter changes of the vertebral artery with a valuable objective basis.
