摘要
目的:探讨彩色多普勒超声(CDUS)对先天性椎动脉发育不良所致椎-基底动脉供血不足(VBI)的诊断价值。方法:用CDUS对200例诊断为VBI患者的椎动脉颅外段的走行、内径、管壁及血流动力学进行观测。结果:200例患者中22例单侧椎动脉内径均匀性偏细,患侧椎动脉内径及Vs、Ved、Vm、Q与健侧比较较低,RI较高,有显著性差异(P<0.01)。结论:彩超为临床诊断先天性椎动脉发育不良致VBI提供了有价值的依据,可作为椎动脉发育不良首选及常规筛查手段。
Objective： To explore the diagnostic value of color ultrasound in vertebrobasilar insuffi- ciency （VBI） caused by congenital vertebral artery hypoplasia. Methods： 200 patients confirmed with VBI were examined by Color Doppler Ultrasonography （CDUS）, and the extracranial segments of vertebral artery, the inner diameter, the,tube wall and hemodynamics were observed. Results： Of the 200 patients, the unilateral vertebral artery diameter of 22 patients was uniformity small. Compared with the normal ones, the affected vertebrarterial diameter, Vs, Ved, Vm and Q were lower, but RI was higher, which were significant different （P〈0.01）. Conclusion： CDUS provides a valuable basis for the clinical diagnosis of VBI caused by congenital vertebral artery hypoplasia, it can be used as the routine screening method for VBI.
