摘　　要：目的探讨先天性椎动脉变异的超声诊断及其临床意义。方法应用彩色多普勒超声对300例疑诊为椎动脉型颈椎病患者进行颅外段椎动脉检查,利用二维图像及彩色血流观测椎动脉内径、走行及起点位置、血流速度等。结果本组300例中68例患者椎动脉颈段入横突孔位置异常;23例一侧椎动脉发育不良,其中2例合并颈段入横突孔位置异常;4例椎动脉起点异常,其中2例仅伴颈段入横突孔位置异常;2例双支左椎动脉,且双支椎动脉中有1支左椎动脉发育不良,1支左椎动脉起点伴颈段入横突孔位置异常。结论彩色多普勒超声可很好的诊断先天性椎动脉变异,具有较高的临床意义。Objective To investigate the ultrasonic diagnosis of congenital variation of extracranial vertebral artery （VA） and its clinical significance. Methods The VA in 300 patients with vertebral artery type of cervical spondylosis were examined by ultrasonography involving the diameter, route, starting point, peak systolic velocity （PSV） etc. Results It was found that the VA in 68 cases had congenital abnormal entrance position into the transverse foramen. Unilateral VA was hypoplastic in 23 cases. Two of the 23 cases, the VA entered into the abnormal position of transverse foramen. Anomalous origin of VA was found in 4 cases, which originating from the aortic arch. Two of the 4 cases only had congenital abnormal entrance position into the transverse foramen. The left VA had 2 branches in 2 cases, one branch was hypoplastic and the other branch had anomalous origin and the abnormal entrance position into the transverse foramen. Conclusion Ultrasonography can be used to diagnose the congenital variation of the vertebral artery and has great clinical significance.
