| 目的 探讨超声检查在腕管综合征(CTS) 诊治中的作用。方法 60只来自50例CTS患者的手腕,经手术证实。50只无CTS症状的手腕。由同一人进行超声检查,矢状位观察正中神经的形态、回声的改变,计算厚度比(厚度比=最小神经厚度/ 最大神经厚度)。横断面测量豌豆骨水平的神经面积。结果 卡压最常见的部位为钩骨勾水平。卡压两端神经肿胀,肿胀处回声减低。CTS 组与对照组在厚度比、豌豆骨水平神经面积这2 个量化指标之间差异明显,各自的诊断阈值为≤0.81>0.11cm2,诊断敏感度为90.2 %、80.2 % ,特异度为88.2 %、88. 4 %。结论 超声检查可以从形态、量化指标两个方面鉴别诊断CTS ,可以发现局部致病病因及解剖变异,为手术方式选择提供帮助。 |

| Objective To evaluate the role of ult rasonography in the diagnosis and t reatment of carpal tunnel syndrome(CTS). Methods Sixty wrist s f rom fifty patient s with CTS confirmed by operations and fifty asymptomatic cont rols under-went ult asonography by the same operator. The configurations and echo of the median nerve were observed in sagittal plane. The maximum and minimum anterior2posterior diameter of the median nerve were measured and the thickness ratiowas calculated. The cross2sectional area at the level of pisiform bone was measured in t ransverse plane. Results The most compressed site located at the hook of the hamate bone. The proximal and the distal part of the compressed nerve swelledup. The echo of the swollen nerve was hypoechoic. Comparing with the cont rol group , the quantitative criteria including the thickness ratio and the cross2sectional area at the level of pisiform bone was significant . The cut2off value of thickness ratio and the cross-sectional area at the level of pisiform bone was ≤0.81and > 0. 11 cm2 . The sensitivity was 90. 2 % and 80. 2 % , and the specificity was 88.2% and 88.4%,respectively. Conclusion Ult rasonography could detect the pathological nerve f rom it s configuration , determine the existence of CTS on quantitive criteria , and be helpful to choose operation meth-ods by discovering some local cause of CTS and anatomic variations. |
