Abstract

The axillary arch is a vestigial muscle in the axilla, which originates from the latissimus dorsi and inserts into the pectoralis major tendon. The aim of this article is to describe a fan-shaped variant of the axillary arch and its clinical implications. We present a patient who underwent an axillary node dissection during which, a fan-shaped axillopectoral muscle measuring 8 cm by 6 cm was encountered. It was disinserted to provide exposure of the axilla.

摘要

腋弓是腋窝内的一块退化肌肉，它起自背阔肌，止于胸大肌腱。本文旨在描述一种扇形变异的腋弓及其临床意义。我们报告一名接受腋窝淋巴结清扫术的患者，术中发现一块大小为8厘米×6厘米的扇形腋胸肌。为暴露腋窝，将其止点离断。
