Neurogenic thoracic outlet syndrome (NTOS) is a heterogeneous and often disputed entity. An electrodiagnostic pattern of T1 > C8 axon involvement is considered characteristic for the diagnosis of NTOS. However, since the advent of high-resolution nerve ultrasound (US) imaging, we have encountered several patients with a proven entrapment of the lower brachial plexus who showed a different, variable electrodiagnostic pattern.

与神经源性胸廓出口综合征相关的电诊断结果的变异性

神经源性胸廓出口综合征 (NTOS) 是一种异质性且经常存在争议的疾病。T1 > C8 轴突受累的电诊断模式被认为是 NTOS 诊断的特征。然而，自从高分辨率神经超声 (US) 成像出现以来，我们遇到了几名经证实存在下臂丛神经卡压的患者，他们表现出不同的、可变的电诊断模式。
