高频超声对上肢神经卡压症的诊断价值

Diagnostic Value of High-Frequency Ultrasound in Upper Extremity Nerve Entrapment Syndrome

目的探讨高频超声在诊断上肢神经卡压症中的应用价值。方法回顾性分析经手术证实的32例上肢神经卡压症患者的高频超声及电生理表现,比较其诊断准确率。结果 32例上肢神经卡压症患者中,16例为正中神经卡压,15例为尺神经卡压,1例为桡神经卡压,超声诊断的准确率为93.8%,电生理诊断的准确率为87.5%。结论高频超声可清晰地显示上肢神经卡压的部位、范围及程度,具有较大的诊断价值,可作为影像学检查的首选方法。

Objective To explore the application value of high-frequency ultrasound in the diagnosis of upper extremity nerve entrapment syndrome. Methods Ultrasound features and eleetromyography results of 32 patients with upper extremity nerve entrapment syndrome confirmed by surgery were retrospectively analyzed, and then the diagnostic accuracies were compared. Results Among the 32 cases, 16 were median nerve entrapment, 15 were ulnar nerve entrapment, and one was involved radial nerve. The diagnostic accuracy of ultrasound was 93.8%, while the diagnostic accuracy of electrophysiology was 87.5%. Gonelusion High-frequency ultrasound which can clearly show the location, scope and extent of upper extremity nerve entrapment, has a high diagnostic value and can be used as the preferred diagnostic method.
