椎动脉起源异常的超声诊断与临床应用

Application of ultrasonography in diagnosis of anomalous origin of vertebral artery

目的探讨彩色多普勒超声在椎动脉起源异常中的诊断价值。方法回顾性分析彩色多普勒超声检测的3393例患者诊断椎动脉起源异常情况。结果 3393例患者中,椎动脉起源异常123例,左侧122例,右侧1例,总发生率3.63%。椎动脉起源主动脉弓为123例,包括单独起源异常3例,起源异常合并走行变异77例,起源异常合并走行变异、发育不良43例,且合并走行变异。结论彩色多普勒超声是无创性诊断椎动脉起源异常、发育不良等变异的优良方法。

Objective To study the application of color Doppler ultrasonography in diagnosis of anomalous origin of vertebral artery （VA）.Methods Clinical data about 3393 patients with color Doppler ultrasonography-confirmed anomalous origin of VA were retrospectively analyzed.Results 123 were diagnosed with anomalous origin of VA （122 patients in left,l paitent in right）.With a total ineidence of 3.63%.Of these 123 patients with anomalous origin of VA from the aortic arch,3 were diagnosed with simple anomalous origin of VA,77 with anomalous origin of VA variations,43 with anomalous origin of VA variations and dysplasia complicating anomalous origin of the right common carotid artery.Conclusion Color Doppler ultrasonography is a useful noninvasive imaging tool for the diagnosis of anomalous origin of VA and dysplasia.
