Variations concerning the origin and course of the suprascapular artery are numerous and present important clinical implications.
In the present study the origin and course of the suprascapular artery are investigated in a sample of Greek (Caucasian) origin.
The anatomy and course of the suprascapular artery were carefully examined in 31 adult human cadavers (16 male and 15 female).
Anomalous origin of the suprascapular artery from the third segment of the subclavian artery was observed in the right side of only one female Caucasian specimen (1/62 = 1.6%). The suprascapular artery and the suprascapular nerve passed together under the superior transverse scapular ligament through the suprascapular notch, whereas the suprascapular vein was absent.
According to the available literature, this type of variation in the origin of the suprascapular artery is considered rare. This variation is clinically important, since it is related to the creation mechanism of suprascapular neuropathy and has also obvious surgical implications. The variation is embryologically enlightened and has an interesting ontogenic aspect.
肩胛上动脉的起源和走行变异众多，具有重要的临床意义。
在本研究中，对希腊（高加索）裔样本的肩胛上动脉的起源和走行进行研究。
在31具成年人体尸体（16例男性和15例女性）中仔细检查肩胛上动脉的解剖结构和走行。
仅在1例女性高加索标本的右侧观察到肩胛上动脉起源于锁骨下动脉第三段的异常情况（1/62 = 1.6%）。肩胛上动脉和肩胛上神经一起穿过肩胛上横韧带下方的肩胛上切迹，而肩胛上静脉缺如。
根据现有文献，肩胛上动脉起源的这种变异类型被认为是罕见的。这种变异在临床上很重要，因为它与肩胛上神经病变的发生机制有关，并且也有明显的手术意义。这种变异在胚胎学上有启示，并且有一个有趣的个体发生学方面。
