【摘要】Objective To investigate the diagnostic value and clinical significance of dual-source CTA in the variation of V3 segment of vertebral artery. Methods A retrospective analysis of 215 patients with head and neck CTA examination from July 2012 to January 2013 in our hospital was conducted. The morphology, trajectory and relationship with the adjacent structures of the V3 segment of the vertebral artery were observed. Comprehensive assessment of the variation of the V3 segment of the vertebral artery. Results Among all 215 cases, 15 cases of vertebral artery V3 segment stroke and branch variation were found, the incidence rate was 7.05%, including 12 cases of C2 segmental vertebral artery, the incidence rate was 5.68%, and the window type vertebral artery occurred in 2 cases. The rate was 0.92%, and the origin of the posterior inferior cerebellar artery was moved down by one case, the incidence rate was 0.56%. After the C1, the vertebral artery sulcus bridge was formed in 13 cases, the incidence rate was 6.05%. Conclusion Dual-source CTA can display the normal anatomy of V3 segment of vertebral artery and find common variations such as stroke, branch and vertebral artery sulcus formation.
