肘管综合征超声定量检测的临床应用价值

目的:探讨肘管综合征(cubital tunnel syndrome,CTS)超声定量诊断的临床应用价值。方法:收集CTS患者33例作为患者组,共39个患病肘关节;选取30例健康志愿者作为对照组,共60个健康肘关节。用高频超声检查2组尺神经,并比较2组间尺神经形态、回声、横截面积(cross sectional area,CSA)及CSA肿胀率的差异。结果:患者组超声声像图中69.2%可见明显卡压,表现为卡压处尺神经局部扁平或变细,卡压的近端及远端肿胀变粗,回声降低;30.8%未见明显卡压,仅表现为肘部尺神经肿胀;尺神经最粗CSA与运动神经传导速度的相关系数r=-0.528。结论:超声对CTS的定量检测中,CSA肿胀率诊断价值最大,CSA和CSA肿胀率相结合能提高诊断灵敏度。

The clinical application value of ultrasonic quantitative testing in cubital tunnel syndrome

Objective： To evaluate the clinical application value of Ultrasonic quantitative diagnosis of cubital tunnel syndrome （CTS）. Methods： The patients group： 39 arms from 33 CTS patients; the control group： 60 arms from 30 healthy volunteers. Ulnar nerves were detected with high-resolutin ultrasonography. Results：The ulnar nerves of 69. 2% patients became narrow or flat at compression site while it turned to enlarged and the fascicular texture turned to vague at the proximal part of the compression,the cross sectional area （CSA） reduced relatively. It could not be found at the compression site in 30.8~ CTS and the nerve was swollen in elbow. The correlation coefficient between maximal CSA and motor nerve conduction velocity （MNCV） was -0. 546. Conclusion：High frequency ultrasound in the diagnosis of CTS, CSA swelling rate has the maximum diagnostic value. CSA combined CSA swelling rate can improve the sensitivity of diagnosis of CTS.
