The brachial plexus represents a field of many anatomical variations with impor- tant clinical implications, especially in the diagnosis and treatment of the thoracic outlet syndrome (TOS). The case described in this paper presented a novel bilateral variation in the relation of the upper trunk of the brachial plexus to the anterior scalene muscle. The ventral rami of the C5 and C6 spinal nerves perforated the anterior scalene muscle simultaneously through a common opening, and joined to form the upper trunk. Previous literature reports described variations of the brachial plexus and the scalene muscles, as well as the embryological basis for their presence. The case reported herein helps to improve the comprehension of the TOS, as well as the diagnostic and therapeutical approach to this syndrome.
臂丛神经存在许多解剖变异情况，具有重要的临床意义，尤其是在胸廓出口综合征（TOS）的诊断和治疗方面。本文所描述的病例呈现了臂丛神经上干与前斜角肌关系的一种新的双侧变异。C5和C6脊神经的腹侧支同时通过一个共同开口穿过前斜角肌，并汇合形成上干。既往文献报道了臂丛神经和斜角肌的变异情况以及它们存在的胚胎学基础。本文报道的病例有助于提高对胸廓出口综合征的理解，以及对该综合征的诊断和治疗方法。
