Abstract

Axillary artery (AA) variants occurred quite commonly, presenting clinical implications. A literature search yielded 523 results from which 13 parameters were extracted. Some of the AA variants found were the fusion of two or more branches into common trunks, like the fusion of anterior and posterior circumflex humeral arteries. Moreover, several branches were found to emerge from different points than expected, like the lateral thoracic artery’s origin from the subscapular artery instead of the second part of the AA. The importance of the knowledge of the AA variations in clinical practice is undeniable and very useful when planning interventional procedures, as in the case of AA aneurysm treatment or in cases of fracture of the surgical neck of the humerus. The heterogeneity of data limited the possibility of a quantitative summary of data. Therefore, a more systemic study of AA variants based on the origin, course, and branching pattern is suggested. The aim of the current review is to summarize current data literature regarding the AA typical anatomy and its variants, with a focus on their prevalence and possible clinical implications.
