【摘要】：目的探讨Ⅱ型糖尿病合并周围神经病变患者高频超声正中神经(MN)横截面积(CSA)的改变及其临床诊断价值。方法测量46例合并神经病变者(C组)、42例不合并者(B组)及42例健康志愿者(A组)MN 6个位点CSA,包括腕横纹处、豌豆骨水平、钩骨水平、腕横纹上方6 cm、肱骨内上髁上4 cm、肱骨中点,采用ROC曲线分析6个位点CSA对DPN的诊断价值。结果 C组较A组所有位点CSA均明显水肿增粗,较B组在腕横纹处,豌豆骨及钩骨水平、腕横纹上方6 cm处增粗,B组较A组在除腕横纹处以外的位点增粗,差异均有统计学意义(P均O.05)。6个位点以钩骨水平CSA诊断价值最高,曲线下面积为0.829,灵敏度为84.8%,特异度为54.8%,最佳临界值为O.097 cm~2。结论高频超声能清晰观察DPN患者MN异常增粗的特征,对其具有重要的临床诊断价值,值得进一步研究和探讨。
[Abstract]:Objective To investigate the changes of high-frequency ultrasound cross-sectional area (CSA) of median nerve (MN) in type 2 diabetic patients with peripheral neuropathy and its clinical diagnostic value. The diagnostic value of six CSA loci was analyzed by ROC curve. Results CSA in group C was more edematous and thicker than that in group A. CSA in group B was thicker than that in group B at wrist stria, pea bone and uncinate bone, 6 cm above wrist stria, and in group B was thicker than that in group A except wrist stria. The difference was statistically significant (P 0.05). Among the 6 sites, uncinate level CSA had the highest diagnostic value, the area under the curve was 0.829, the sensitivity was 84.8%, the specificity was 54.8%, and the best critical value was 0.097 cm~2. Conclusion High frequency ultrasound can clearly observe the characteristics of abnormal MN thickening in DPN patients, which has important clinical diagnostic value and is worth further study. And discuss.
