Reconstructive surgery uses various musculocutaneous flaps following resection of head and neck malignant tumor. Numerous anatomical studies have reported that the thoracoacromial artery arises from the axillary artery, but those findings have not been completely confirmed. The aim of this study was to investigate the path from the origin of the thoracoacromial artery until its pectoral branches enter the pectoralis major muscle. The following results were obtained. 1. There were no cases in which the thoracoacromial artery arose from the third part of the axillary artery. 2. There were differences between the left and right sides in the vertical and horizontal origins of the thoracoacromial artery in relation to the clavicle and median line. 3. Pectoral branches showed a single origin from the thoracoacromial artery most frequently. 4. Pectoral branches descend in parallel to the median line most frequently on the right side and descended medially to the median line most frequently on the left side. 5. The largest number of branches approached the venter vertically at the height of the third rib. There findings suggest that, during operations involving a musculocutaneous flap, the surgeon must pay attention to the differences in vascular morphology of the right and left sides.
重建手术在头颈部恶性肿瘤切除后使用各种肌皮瓣。许多解剖学研究报告称胸肩峰动脉起自腋动脉，但这些发现尚未得到完全证实。本研究的目的是调查胸肩峰动脉从起源到其胸肌分支进入胸大肌的路径。获得了以下结果。1. 没有胸肩峰动脉起自腋动脉第三段的病例。2. 胸肩峰动脉相对于锁骨和中线的垂直和水平起源在左右两侧存在差异。3. 胸肌分支最常从胸肩峰动脉单一起源。4. 右侧胸肌分支最常与中线平行下降，左侧最常向中线内侧下降。5. 最大数量的分支在第三肋高度垂直靠近腹侧。这些发现表明，在涉及肌皮瓣的手术中，外科医生必须注意左右两侧血管形态的差异。
