An uncommon and often-overlooked anatomic variation of the latissimus dorsi muscle is the axillary arch. It is formed by an anomalous slip of the muscle that arises from the body of the latissimus dorsi but then inserts along with the pectoralis major muscle anterior to the axillary vein and neurovascular bundle. If an axillary arch is encountered during axillary lymphadenectomy, the lymph nodes posterior and lateral to the arch should be excised. Experience with a number of cases is used to consider local therapeutic and staging factors.
背阔肌一种不常见且常被忽视的解剖变异是腋弓。它由背阔肌主体发出的异常肌束形成,该肌束随后与胸大肌一起附着于腋静脉和神经血管束前方。如果在腋窝淋巴结清扫术中遇到腋弓,应切除弓后方和外侧的淋巴结。结合多例病例的经验来考虑局部治疗和分期因素。
