Anterior and Posterior Circumflex Humeral Arteries
Abstract
The branches of the third part of the axillary artery are subject to great variation. The two circumflex arteries may arise from a common trunk (20% of individuals, Poynter; 6%, according to Quain; 22%, Pellegrini; 16%, Hitzrot), usually alone or rarely together with profunda brachii and muscular branches. In a study of 610 limbs, the anterior artery had a common origin with a neighboring vessel in 20.2% of cases, most frequently with the posterior artery (13.4%). It is usually small, is doubled in 8% of cases, and is the last branch of the axillary in 35% (Poynter).

The two circumflex arteries together or the anterior circumflex alone may be the only branch of the third part of the axillary.
In some cases, the posterior circumflex humeral arises from the profunda brachii or from the subscapular artery (10%).
The anterior and the posterior circumflex humeral arteries may be doubled.
Based upon 104 subjects by Pellegrini (author 1) and from studies performed by Dubreuil-Chambardel (author 2).
