Knowledge of anatomical variations of the limb's main arteries is significant for the clinicians. Thus, this study is aimed at examining the branching pattern and anatomical variations of the axillary artery. We conducted research on 59 upper limbs of adult human donated cadavers. All axillary artery branches' origins were assessed, and the correlations between points of origins and variations of specific branches were evaluated. The average length of the axillary artery was found to be 11.22 cm, and this length was defined as reference line. Based on this reference line, the first, second, and third parts were 37.56%, 39%, and 30.05%, respectively. The STA was originated from 25.11%. The TAA and LTA were 42.67% and 54.82%, respectively. The SSA, ACHA, and PCHA were 64.72%, 83.89%, and 84.53%, respectively. The origin of LTA was correlated with that of SSA ( = 0.473, < 0.05) and AHCA ( = 0.307, < 0.05), respectively. And there was a positive correlation between AHCA and PHCA ( = 0.705, < 0.05). The number of branches ranged from 3~6, and 9 types were shown. The most frequent branching pattern was common origin of the LTA and SSA (22/59). And AHCA and PHCA were originated together in 19 cases, and both patterns were combined in 12 cases. TTA and LTA branched together in 9 cases, and common trunk for the SSA, PHCA, and AHCA was found in 2 cases. According to this pattern, the origin of LTA and PCHA was significantly different. This information is particularly useful for surgeons and clinicians.
肢体主要动脉解剖变异的知识对临床医生来说意义重大。因此，本研究旨在检查腋动脉的分支模式和解剖变异。我们对 59 具成人尸体捐献上肢进行了研究。评估了所有腋动脉分支的起源，并评估了特定分支起源点和变异之间的相关性。腋动脉的平均长度为 11.22cm，将其定义为参考线。基于这条参考线，第一、第二和第三部分分别为 37.56%、39%和 30.05%。STA 起源于 25.11%。TAA 和 LTA 分别为 42.67%和 54.82%。SSA、ACHA 和 PCHA 分别为 64.72%、83.89%和 84.53%。LTA 的起源与 SSA（=0.473，<0.05）和 ACHA（=0.307，<0.05）相关。AHCA 与 PHCA 之间存在正相关（=0.705，<0.05）。分支数量范围为 3~6，共显示 9 种类型。最常见的分支模式是 LTA 和 SSA 的共同起源（22/59）。19 例 AHCA 和 PHCA 起源于一起，12 例两者结合。9 例 TTA 和 LTA 分支在一起，2 例 SSA、PHCA 和 ACHA 的共同干。根据这种模式，LTA 和 PCHA 的起源有显著差异。这些信息对外科医生和临床医生特别有用。
