Bilateral superfi cial brachial artery
Sharma T, Singla RK, Sachdeva K

Variations of the upper limb arterial system are well documented. Accurate knowledge of the normal and variant arterial anatomy of the axillary artery is important for clinical procedures and vascular radiology. In this article, a rare bilateral variation of superfi cial brachial artery is being reported. The axillary artery on both sides divided in its third part into a superfi cial brachial artery passing superfi cial to the lateral root of median nerve and brachial artery proper. The former terminated in the cubital fossa by dividing into ulnar and radial arteries while the later descended deep to the medial root of median nerve and gave anterior and posterior circumfl ex humeral branches of axillary artery and profunda brachii of brachial artery. Then it terminated by giving twigs to muscles of arm. Earlier superfi cial brachial artery is reported with a prevalence rate varying from 0.2 – 25 % but a bilateral variation is extremely rare. Further its ontogeny and clinical implications are discussed in detail.
