腋动脉以胸小肌上下缘为界分为3段。腋动脉分支变异较多,多见于胸外侧动脉和肩胛下动脉起点变异~([1-11]),而在同一尸体上腋动脉多个分支都发生变异相对较少。本文作者在解剖1具中年男性尸体时,发现其双侧腋动脉多个分支变异,几个主要分支不直接发自腋动脉,而是由变异动脉共干发出;双侧胸上动脉缺如。同时,其分支主要走行也发生罕见变化,左侧旋肩胛动脉不穿行三边孔,而是穿小圆肌;左侧旋肱后动脉既不穿行四边 Axillary artery to the pectoralis minor upper and lower edge is divided into 3 sections. Axillary artery branch variation more common in the extrathoracic artery and subscapular artery at the beginning of variation ~ ([1-11]), while in the same carcass axillary artery multiple branches have occurred relatively few variations. When dissecting a body of a middle-aged male, the author found multiple branches of the bilateral axillary artery. Several major branches were not directly originated from the axillary artery but were co-stemmed by the variant artery. The absence of bilateral suprathoracic arteries . At the same time, the main branch of its branch also occurred rare changes in the left spinous artery without traversing the trilateral hole, but wearing a small round muscle; left posterior humeral artery neither through the four sides
