Dissection of the thoracic inlet was performed on 22 cadavers to determine the relationship of the phrenic nerve to the internal mammary artery as it passes from lateral to medial behind the first rib. On the left the nerve was found to cross superior to the artery and then medial to it in 14 of 22 specimens; on the right this was found in ten of 22 specimens. In all other specimens, it crossed inferior to the internal mammary artery. These findings demonstrate that there is no constant relationship between these structures, and emphasize the need for caution when dissecting the internal mammary artery at or above the level of the first rib.
对22具尸体进行胸廓入口解剖，以确定膈神经在第一肋后方从外侧向内侧走行时与胸廓内动脉的关系。在左侧，22个标本中有14个发现神经在动脉上方交叉，然后在其内侧；在右侧，22个标本中有10个发现这种情况。在所有其他标本中，神经在胸廓内动脉下方交叉。这些发现表明这些结构之间没有恒定的关系，并强调在第一肋水平或以上解剖胸廓内动脉时需要谨慎。
