Unilateral Variation in the Branching Pattern of Right Axillary Artery: A Case Report

Abstract

Axillary artery and its branches are prone to have variations in their course. Knowledge about such variations are important for Radiologists in imaging techniques, Surgeons,Orthopedicians and Anesthetists in performing surgeries in the axilla and giving regional nerve blocks in the axilla.During dissection of a cadaver in the department of Anatomy, PSG IMS &R, Coimbatore, India. We observed a variation in the third part of right Axillary artery. From the common trunk, Subscapular artery, Anterior and Posterior circumflex humeral arteries and Profunda brachii artery arose. Third part of Axillary artery continued down as brachial artery. We are highlighting the variation in this study.

Unilateral Variation in Branching Pattern of Third Part of Left Axillary Artery: A Case Report

“…A K Manicka Vasuki et al reported that third part of axillary artery gave a common trunk which further divided in to subscapular artery anterioir circumplex humeral artery posterior circumflex artery and pronda branchii artery. This study correlates with our study but only difference is they found in right axillary artery but we found in left axillary artery [10].…”

Bilateral Variations in Branching of Axillary Artery

“…Swamy et al [6] described a variant subscapular artery taking origin from second part of axillary artery and giving rise to posterior circumflex humeral and lateral thoracic artery. Vasuki et al [7] encountered variations in the third part of axillary artery on the right side. In the present case a common trunk took origin from second part of axillary artery and then gave rise to lateral thoracic artery and circumflex scapular artery on both sides.…”
