摘　　要：目的:评价高频超声联合应用低频超声诊断椎动脉先天性变异的临床价值。方法:536例拟诊为眩晕患者应用高频超声结合低频超声观察椎动脉起源、穿入位置、内径、走行、血流动力学改变。结果:536例中21例左侧椎动脉异位起源主动脉弓合并高位入颈椎横突孔,1例起源于右侧颈总动脉并高位入颈椎横突孔,41例41根椎动脉单纯高位入横突孔,35例一侧椎动脉发育不良。结论:高频超声联合应用低频超声能很好的诊断先天性椎动脉变异,具有较高的临床意义。Objective： To evaluate the clinical value in the diagnosis of congenital variation of vertebral artery（ VA） by using high-frequency ultrasound combined with low-frequency ultrasound. Methods： The VA of 536 cases with suspected cervical venigo were examined by ultrasonography,involving starting point,the entry position of vertebral artery into the transverse foramen,the diameter,route,peak systolic velocity（ PSV） etc. Results： Among 536 cases,anomalous origin of VA was found in 21 cases which originating from the aortic arch. All of the cases had congenital abnormal entrance position into the transverse foramen. 1 case originated from the right common carotid artery. It was found that the VA in 41 cases only had congenital abnormal entrance position into the transverse foramen. Unilateral VA was hypoplastic in35 cases. Conclusion： High-frequency and low-frequency ultrasound can be used to diagnose the congenital variation of the vertebral artery and has great clinical significance.
