Abnormal division of axillary artery - A case report

Abstract

A case of the abnormal branching of the right Axillary artery in a 60 year old male cadaver is presented here. The axillary artery divided into two trunks, a lateral and medial from the second part only in this case, The lateral branch was superficial running between two roots of median nerve, which here is referred to as superficial branch. The other was a medial trunk, running deep to median nerve on the medial, hence it is referred as deep brachial artery. The superficial branch had a similar course as radial artery coursing on the lateral side of cubital fossa, fore arm, anatomical snuff box and hand, hence it was considered as equivalent to radial artery. The deep brachial artery gave rise to anterior and posterior circumflex humeral arteries and the superior ulnar collateral artery. This variation is rare and the on the right side, where the course and distribution of incidence quoted as around 0.12 - 3.2% in the available literature. The normal and abnormal anatomy of the The axillary artery is having practical importance for the radiologists during angiography and surgeons for accurate diagnostic interpretation.
