探讨椎动脉畸形的临床表现、诊断及治疗。方法：采用椎动脉造影及椎动脉磁共振血管成象（MRA），对31例颈性眩晕病例进行了检查。结果：有5例椎动脉畸形；其中2例为右侧椎动脉发育不良，1例为左侧椎动脉发育不良，1例为左侧椎动脉缺如，1例为双侧椎动脉走行异常。5例中有3例会并枕颈畸形。椎动脉畸形组和正常组比较，手术效果无显著性差异，但病程和体征有显著性差异。结论：在椎动脉畸形基础上，如果出现颈椎不稳，则容易发生颈性眩晕，颈椎融合治疗效果好。
To investigate the clinical manifestations, diagnosis and treatment of vertebral artery malformations. Methods: Vertebral artery angiography and magnetic resonance angiography (MRA) of vertebral artery were performed in 31 cases of cervical vertigo. Results: There were 5 cases of vertebral artery deformity, 2 cases of right vertebral artery dysplasia, 1 case of left lateral vertebral artery dysplasia, 1 case of left vertebral artery defect and 1 case of bilateral vertebral artery anomalies. Three of the five cases had occipitocervical deformities. Vertebral artery malformation group compared with the normal group, no significant difference in operative effect, but the duration and signs were significantly different. Conclusion: On the basis of vertebral artery deformity, if cervical spine instability occurs, cervical vertigo is easy to occur and the effect of cervical fusion is good.
