超声对观察椎动脉椎骨段走行的诊断意义

目的探讨超声对观察椎动脉椎骨段走行的诊断价值。方法对162例患者（走行异常者经血管造影或MRI等其他检查证实）的双侧椎动脉走行的二维和彩色血流信号等声像图信息进行回顾性分析，对椎动脉椎骨段走行异常作出诊断及分型。结果（1）超声通过二维或彩色多普勒的血流信号可显示椎骨段椎动脉有无、穿人位置和走行形态。（2）超声根据椎骨段椎动脉的有无、穿入位置和在椎骨段中的走行形态可将椎动脉椎骨段走行异常分为缺如0．6％（2／324），走行变异2．7％（9／324），走行弯曲5．5％（18／324）三大类。结论超声能清晰显示椎动脉椎骨段的有无、穿人位置及走行形态，能对椎动脉椎骨段的走行异常作出分型诊断，在形态学上为临床明确椎动脉的病因提供帮助。

Significance of Ultrasonic Diagnosis in Observation of Running of Intervertebral Segment of Vertebral Artery

Objective To investigation the ultrasonic siganificance in observing and diagnosising the running of intervertebral segment of vertebral artery. Methods The two-dimensional and colour Doppler blood flow ultrasonograms were reviewed for the running of two-side intervertebral segment of vertebral artery in 162 patients （ the abnormal running was confirmed by angiography or MRI）. Results （ 1 ） The running of intervertebral segment could be showed clearly by ultrasound. （2） According to the ultrasonograms of the entrance and the shape of intervertebral segment of vertebral artery, the running type was divided as lacking in 0.6% （2/324）, variational in 2.7% （9/324） and curving in 5.5% （18/324）. Conclusion The abnormal running of intervertebral segment of vertebral artery can be diagnosed via ultrasound, which helps to choice the best treatment.
