摘要

目的:探讨高频超声对检测不同病程糖尿病周围神经病变(diabetic peripheral neuropathy,DPN)患者趾短伸肌(extensor digitorum brevis muscle,EDB)萎缩的诊断价值。方法:应用高频超声对53例DPN患者、49例非DPN患者以及52例健康志愿者非优势足的EDB进行扫查,观察其内部回声,测量最大厚度及横截面积(cross-sectional area,CSA)。将53例DPN患者按病程分为5~10年、11~15年以及>15年3小组,比较不同病程患者EDB的厚度及CSA。结果: 正常对照组的EDB形态饱满,厚度及CSA大于DPN组及非DPN组,差异有统计学意义(P<0.05)。不同病程DPN患者中,>15年组EDB厚度及CSA较11~15年组明显减小,11~15年组较5~10年组明显减小,差异均有统计学意义(P<0.05)。结论:高频超声可显示趾短伸肌的声像图改变,可通过测量肌肉的厚度和CSA反映不同病程DPN患者EDB的萎缩情况,具有一定的诊断价值,为临床的早发现早诊断早治疗提供了相应的影像学依据。

Abstract

Objective: To explore the diagnostic value of high frequency ultrasound in detecting the atrophy of extensor digitorum brevis (EDB) in patients with different course of diabetic peripheral neuropathy. Methods: The EDB of 53 DPN patients, 49 non-DPN patients and 52 healthy volunteers were scanned by high frequency ultrasound to observe the internal echo, measure the maximum thickness and cross-sectional area. The patients in group DPN were divided into three groups according to the course of disease: 5–10 years, 11–15 years, and >15 years, compared the ultrasonic images of the of patients with different courses of disease, and observed the differences between the thickness and CSA. Results: In the normal control group, the shapes of extensor digitorum brevis were plump. The thickness and cross-sectional area of control group were larger than those of DPN group and non-DPN group. The difference was statistically significant (P<0.05). In DPN patients with different courses of disease, the thickness and CSA of the EDB in the group of >15 years were significantly lower than those in the group of 11–15 years, and the thickness and CSA in the group of 11–15 years were significantly lower than those in the group of 5–10 years, differences were statistically significant (P<0.05). Conclusion: High frequency ultrasound can show the changes of the ultrasonogram of extensor digitorum brevis. It can measure the thickness and cross-sectional area of the muscle to reflect the atrophy of EDB in DPN patients with different courses of disease. It has certain diagnostic value and provides the corresponding imaging basis for the early diagnosis and early treatment of clinical early detection.
