Thoracic outlet syndrome (TOS) and its diagnosis have been topics of controversy, fueled in part by the lack of an objective test for early diagnosis. True neurogenic TOS results in diagnostic EMG findings only in its later stages. We describe a series of patients in whom the diagnosis is supported by changes in the medial antebrachial cutaneous (MAC) nerve at or before the development of these typical EMG findings in median and ulnar nerves.
胸廓出口综合征（TOS）及其诊断一直是颇具争议的话题，部分原因是缺乏用于早期诊断的客观检查。真正的神经源性TOS仅在其后期才会导致诊断性肌电图（EMG）结果。我们描述了一系列患者，在正中神经和尺神经出现这些典型EMG结果之前或之时，臂内侧皮神经（MAC）的变化支持了对这些患者的诊断。
