The pattern of arterial supply to the various parts (clavicular, sternocostal and aponeurotic) of the pectoralis major muscle was studied in 7 cadaver dissections and 10 angiograms by injecting a radio-opaque substance. Three main arteries supplied the muscle, i.e. the pectoral branch of the thoracoacromial trunk (TAT-PB), the lateral thoracic artery and the perorating branch of the internal thoracic artery, supported by other branches of the TAT and the superior thoracic artery. It is observed that the TAT-PB, a chief vascular pedicle, anastomoses freely with other arteries and supplies most parts of the muscle. The present study is mainly focussed on the exclusion of the chief vascular pedicle of muscle to eliminate the confusion of previous studies and prevent the unnecessary hindrance and complications of the muscle flap.
通过向7具尸体标本和10份血管造影图像中注入不透射线的物质，研究了胸大肌各部分（锁骨部、胸肋部和腱膜部）的动脉供应模式。三条主要动脉为该肌肉供血，即胸肩峰干的胸肌支（TAT-PB）、胸外侧动脉和胸廓内动脉的穿支，并得到胸肩峰动脉其他分支和胸上动脉的支持。据观察，作为主要血管蒂的TAT-PB可与其他动脉自由吻合，并为肌肉的大部分区域供血。本研究主要集中于排除肌肉的主要血管蒂，以消除以往研究中的混淆，并防止肌皮瓣出现不必要的阻碍和并发症。
