摘　　要：目的应用高频超声探讨2型糖尿病周围神经病变(DPN)患者上肢神经多个位点的横截面积的变化及其临床意义。方法对30例确诊为DPN的患者和30例健康对照者应用高频超声检查上肢正中神经、尺神经和桡神经的多个位点:包括正中神经腕管处、前臂中点、肘窝处及上臂中点的横截面积;尺神经平腕横纹处、前臂中点、肘管处及上臂中点的横截面积;桡神经桡神经沟处、肘窝处的横截面积,对比分析各位点的横截面积及神经的声像图特点并探讨其诊断价值。结果 DPN组正中神经在腕管处、前臂中点、肘窝处和上臂中点处的横截面积,尺神经在腕横纹处、肘管处和上臂中点处的横截面积,桡神经在桡神经沟的横截面积均大于对照组,差异有统计学意义(P<0.05)。结论超声检查可以为DPN的早期发现和评价提供临床依据。Objective To investigate the changes of crosssectional area（CSA） of multiple sites of upper extremity nerve in patients with type 2 diabetes mellitus with peripheral neuropathy by highfrequency ultrasonographyand its clinical significance.Methods Highfrequency ultrasonography was performed on 30 patients with type 2 diabetes mellitus complicated with peripheral neuropathy and 30 healthy controls to examine multiple sites of the median nerve（MN）, ulnar nerve（UN） and radial nerve（RN） of the upper limb, including the CSA of MN at Carpal tunnel, forearm midpoint, elbow fossa and midpoint of the upper arm, the CSA of UN at the rasceta, forearm midpoint side leg and midpoint of the upper arm, the CSA of RN at the elbow and the radial groove. Comparative analysis was made on the crosssectional area and ultrasonographic characteristic of each site and their diagnosticvalueswere also explored.Results The crosssectional area of median nerve at wrist canal, midpoint of forearm, chelidon and midpoint of upper arm, the crosssectional area of ulnar nerve at wrist stria, elbow canal and midpoint of upper arm, and the crosssectional area of radial nerve in radial nerve groove in type 2 diabetic peripheral neuropathy group were all larger than those in normal control group （P〈0.05）.Conclusion Ultrasonography may provide a clinical basis for the early detection and evaluation of type 2 diabetic peripheral neuropathy.
