Abstract :
During a routine anatomical dissection of a 70-year-old male cadaver, we found that this specimen had an unusual branching pattern of the third part of the axillary artery. On the right side, the third part of the axillary artery had a common trunk originating from it. The common trunk gave rise to four arteries: the subscapular artery medially and the anterior and posterior circumflex humeral arteries laterally. In contrast, the common trunk continued as the profunda brachii artery (deep brachial artery). It is terminated by dividing into two arteries, the middle collateral and the radial collateral arteries.
