Abstract

Anatomic variations in branching pattern of axillary artery (AxA) are common and typically involve subscapular artery (SsA) and posterior circumflex humeral artery (PCHA). Several skin and muscle flaps are based on the branches of AxA. Furthermore, these branches are frequently used as recipient vessels in functioning free muscle transfers for upper extremity reconstruction and in breast reconstruction. Accurate knowledge of the normal anatomy and variations in branching pattern of AxA is of significant clinical importance for the reconstructive microsurgeon. The purpose of this article is to report the variable branching pattern of AxA based on multidetector-row computed tomography angiography study of 62 upper extremities. The thoracoacromial artery consistently originated from the first or second part of AxA. The classic origin and branching patterns of SsA and PCHA were observed in 21 cases (33.9%). Anatomic variations of SsA and PCHA were observed in 41 upper extremities (66.1%). In addition to the classic pattern, five distinct variations were noted.
