椎动脉闭塞24例超声诊断分析

Clinical analysis on the diagnosis of vertebral artery occlusion by color doppler echocardiography in 24 cases

【目的】探讨彩色多普勒超声心动图(CDE)诊断椎动脉闭塞的临床应用价值。【方法】回顾性总结经CDE诊断的24例椎动脉闭塞病例,并与CT血管造影(CTA)结果进行对比分析。【结果】24例经CDE诊断的椎动脉闭塞,与CTA结果相比,诊断符合率约91.67%(22/24)。闭塞侧椎动脉内径较健侧椎动脉及正常对照组细(P<0.05),健侧椎动脉多普勒血流频谱与正常对照组比较,收缩期峰值血流速度(PSV)、舒张末期血流速度(EDV)均加快,血流阻力指数(RI)降低(P<0.05),内径无明显差别(P>0.05)。【结论】CDE在椎动脉闭塞的诊断中具有较高的临床应用价值。

[ Objective ] To investigate the clinical application of vertebral artery occlusion diagnosis by color doppler echocardiography （CDE）. [ Methods] The 24 cases of vertebral artery occlusion diagnosed by CDE were comparatively analyzed retrospectively with their results of CT angiography （CTA）. [Results] The diagnostic accordance rate of vertebral artery occlusion, the results of CDE compared with those of CTA, was 91.67% （22/24）. Internal diameter of the occlusion side was thinas compared with that of the uninjured side and normal control （P 〈 0.05）.Compared with those of normal control, the peak systolic velocity （PSV）and end diastolic velocity （EDV）of the uninjured side became quick, and resistant index decreased （P 〈 0.05）, however, the internal diameter were no difference（P 〉 0.05 ）. [ Conclusion ] CDE have high clinical value on the diagnosis of vertebral artery occlusion.
