The pattern of blood supply to the clavicular and sternocostal portions of the pectoralis major muscle was studied in the cadaver with X-rays of injected specimens. The major blood supply to the sternocostal part was derived from the pectoral branch, although in about 50% of cases the clavicular branch provided minor contributions. This finding supports the clinical experience that it is safe to isolate the full length of the vascular pedicle, deep to the clavicular portion of the muscle, in the preparation of a pectoralis major myocutaneous flap.
在尸体上通过对注入标本进行X射线检查，研究了胸大肌锁骨部和胸肋部的血液供应模式。胸肋部的主要血液供应来自胸肌支，不过在约50%的病例中，锁骨支也有少量供血。这一发现支持了临床经验，即在制备胸大肌肌皮瓣时，在肌肉锁骨部深层分离血管蒂全长是安全的。
