Application of Three-dimensional Computed Tomography Angiography in the Diagnosis of Cervical Spondylosis with Vertebral Artery Involvement / 中国医科大学学报

ABSTRACT

Objective To explore the use of three-dimensional computed tomography angiography (3D CTA) in the diagnosis of cervical spondylosis with vertebral artery involvement.Methods The study group included 45 patients treated for cervical spondylosis with vertebral artery involvement,from January 2014 to July 2015;42 healthy volunteers were selected as the control group.3D CTA data of all research subjects were evaluated.Results The findings in the experimental group included 3 patients with normal vertebral artery,8 with unilateral narrowed lumen,2 with aberrant route,3 with vascular sclerosis,8 with local lumen stenosis,3 with left side compression,4 with right side compression,and 5 with vessel tortuosity.The right vertebral artery transverse diameter and radius,the left vertebral artery transverse diameter and radius,and 3D images of the left vertebral artery diameter,right transverse diameter,right radius,and left transverse process inner diameter showed statistically significant differences between the two groups (P ＜ 0.05).Conclusion 3D CTA can be used for accurate diagnosis of cervical spondylosis with vertebral artery involvement and can clearly display the diameter of the vertebral artery and the transverse diameter of the vertebral artery.
