目的探讨非创伤性上肢神经束扭转的超声诊断价值.方法对13例上肢神经扭转的患者进行超声检查,分析其高频超声声像图特征,并与临床外科手术进行对照.结果高频超声均可清晰显示神经束的走行及内部结构,并精确定位扭转的神经束,以及神经扭转的位置及累及范围.神经束扭转声像图表现为单发或者多节段性沙漏样改变,沙漏样改变两端神经束增粗,回声减低,内部筛网状束膜结构显示不清.结论高频超声是诊断上肢外周神经非创伤性扭转的首选影像学检查方法.

Objective To study the diagnosis value of high frequency sonography in nontraumatic upper limb nerve torsion.Methods High frequency sonography images of thirteen patients with diagnosed nontraumatic upper limb nerve torsion were retrospective analyzed.The sonography features were compared with the clinical surgery.Results The position and internal structure of nerve can be found by high frequency ultrasound,and which nerve fascicle,location and scope of nerve torsion can be displayed clearly.The features of high frequency sonography was single or multi-segmental hourglass-like change,the two sides of nerve with hourglass like change was thickened,the echo was low,and perineurium structures in upper limb nerve was blurry.Conclusions High frequency sonography is the preferred imaging method for diagnosis of nontraumatic upper limb nerve torsion.
