Abstract

Anatomical variations of the formation and distribution of the brachial plexus are fairly common and it is related to the embryological development of upper limbs. The present report describes an unusual variation of the brachial plexus in which the cords are arranged lateral to the 1st and 2nd parts of the axillary artery. Therefore, some of the main terminal branches show different relationship to the 3rd part of the axillary artery and the brachial artery. Awareness of such variations of the formation, relations and distribution of main branches of brachial plexus is of remarkable clinical importance for clinicians who carry out surgical, interventional radiological and anaesthetic procedures in the axillary region.
