Significance of vertebral artery course variation on color Doppler flow imaging

Gong Xin-huan

Abstract

Objective: To evaluate the diagnostic value of color Doppler flow dynamic changes in patients with vertebral artery course variation. Methods: The blood flow parameters of 113 patients with vertebral artery course variation among 1161 patients with cervical spondylopathy were statistically analyzed and compared to the control group. Results: The sonographic manifestations in the ipsilateral course variation vertebral artery revealed that: the diameter and flow velocity were decreased, PI and RI were increased. Conclusion: Color Doppler flow imaging is a useful noninvasive method for the diagnosis of vertebral artery course variation.
