The axillary arch is the main variation of the axillary muscle. It was first described by Ramsay in 1795. In its classical form, it arises from the latissimus dorsi muscle and extends from this towards the pectoralis major, crossing the base of the axilla and creating a close relationship with the elements of the axillary neurovascular bundle. We describe the finding of 9 axillary arches, including one case of a bilateral arrangement. We develop a searching and finding technique for the axillary arch, essential for the safe and successful development of surgical procedures in the axillary region. Knowledge of this muscle variation and the possibility of finding it during axillary procedures is crucial for lymph node staging and lymphadenectomy and is also important for differential diagnosis in compressive pathologies of the axillary vessels and brachial plexus.
腋弓是腋肌的主要变异形式。它于1795年由拉姆齐首次描述。其典型形态是起自背阔肌，从该肌向胸大肌延伸，穿过腋窝底部，并与腋神经血管束的各组成部分形成紧密关系。我们描述了9例腋弓的发现情况，其中包括1例双侧腋弓的病例。我们开发了一种用于寻找腋弓的技术，这对于在腋窝区域安全、成功地开展外科手术至关重要。了解这种肌肉变异情况以及在腋窝手术过程中发现它的可能性，对于淋巴结分期和淋巴结切除术至关重要，对于腋窝血管和臂丛神经压迫性病变的鉴别诊断也很重要。
