| 目的：评估彩超多参数综合诊断腕管综合症的效能。方法：二维超声观察腕管水平及以上正中神经走形、内部回声、粗细情况，进一步测量腕管入口水平正中神经的横截面积（CSA1），旋前方肌水平正中神经的横截面积（CSA2），比较面积差（ΔCSA=CSA1-CSA2）和面积比（腕-前臂比）（WFR=CSA1/CSA2）；CDFI观察正中神经内血流信号的情况；运动实验测量腕管入口水平腕关节屈曲时正中神经的运动形变系数（MDC），压缩时正中神经的压缩形变系数（CDC）。结果：1、28个CTS超声图像表现为：腕管入口水平及以上MN水肿增粗，回声减低，平行线样回声和网状结构模糊或消失；2、本研究中CSA诊断CTS的截断值为10.40mm2，敏感性（82.1%）及特异性（86.7%）均较高。ΔCSA及WFR诊断CTS的截断值分别为5.15mm、2.55，ΔCSA诊断CTS的敏感性较高，WFR诊断CTS的敏感性（75.0%）及特异性（73.3%）。正中神经运动变形系数（MDC）及压缩变形系数（CDC）诊断CTS的截断值分别1.45、0.95，其诊断CTS的敏感性均较高而特异性不高；3、ΔCSA+CDFI+运动实验诊断CTS具有较高的敏感性（96.2%）和特异性（100%）。结论：彩超多参数结合能提高诊断腕管综合症的效能。 |

| Abstract: |
| Objective: To evaluate the efficacy of color Doppler ultrasound multi-parameter comprehensive diagnosis of carpal tunnel syndrome (CTS).Methods: Two-dimensional ultrasonography was performed to observe the shape, internal echo and thickness of the the median nerve in carpal tunnel level and above. The cross-sectional area (CSA1) at the entrance level of the carpal tunnel and the cross-sectional area (CSA2) at the level of Rotating anterior muscle of the median nerve (MN) was further measured, and then compared area difference (ΔCSA=CSA1-CSA2) and wrist-forearm area ratio (WFR=CSA1/CSA2); CDFI was used to observe the flow signal of the median nerve ; exercise test was used to measure the move deformation coefficient of the median nerve (MDC) and the compression coefficient (CDC) of the median nerve during compression at the entrance level of the tube.Results: 1,ultrasound images feature of 28 CTS: Edema and thickening, echo reduction, parallel line echo and reticular structure blurred or disappeared of MN; 2, In this study, the CSA cut-off value was 10.40 mm2, and the sensitivity (82.1%) and specificity (86.7%) were higher in diagnostic CTS. The cut-off values of ΔCSA and WFR for diagnosis of CTS were 5.15 mm and 2.55, respectively. The sensitivity of ΔCSA for the diagnosis of CTS was higher, and the sensitivity (75.0%) and specificity (73.3%) for WTS diagnosis of CTS. The median nerve motor deformation coefficient (MDC) and compression deformation coefficient (CDC) cutoff values of 1.45 and 0.95 respectively in diagnose of CTS , and their sensitivity to diagnosis of CTS is high and the specificity is not high;3,CSA+CDFI+exercise test diagnosis CTS has higher sensitivity and specificity. Conclusion: Color Doppler multi-parameter combination can improve the efficacy of diagnosis of carpal tunnel syndrome. |
