Abstract
Summary A case of an unusual variation of the blood supply of an upper limb is presented. During a routine anatomical dissection, it was found that the posterior circumflex humeral artery had an unusual course and branching. It arose as a branch of the brachial artery, not the axillary one, and it did not accompany the axillary nerve. It ran under the lower border of the teres major muscle instead of passing through the lateral axillary foramen, then followed its usual course around the surgical neck of the humerus, supplying the deltoid muscle. It was also found that instead of arising from the brachial artery, the deep brachial artery arose from the posterior circumflex humeral artery. Variations are reported and their clinical relevance is discussed.
