腋动脉分支的类型和数目变异较为常见,国内外专著一般将腋动脉的分支描述为典型的6支型。我们在解剖一具女性尸体标本(身长约150 cm,83岁)时,见其右腋动脉分支为2支型,除从主干发出1支细小的胸外侧动脉外,只发出1支动脉干,这种变异较为少见,为积累解剖学资料并为临床工作提供形态学依据,现报道如下:该例腋动脉自第1肋续于锁骨下动脉,行于臂丛内侧束的前 The types and numbers of axillary branches are more common. The domestic and foreign monographs generally describe the branch of axillary artery as a typical 6-branch type. When we dissected a female body specimen (about 150 cm in length and 83 years of age), we found that the right axillary branch was divided into two branches. Only one branch of the trunk was emanated except one small thoracic artery from the trunk, This variation is rare, in order to accumulate anatomic data and provide morphological evidence for clinical work, are reported as follows: The axillary artery in this case from the first rib continued in the subclavian artery, the line in the front of the medial bundle of brachial plexus
