Structure

Its origin is at the lower margin of the teres major muscle and a continuation of the brachial vein.[1]

This large vein is formed by the brachial vein and the basilic vein.[2] At its terminal part, it is also joined by the cephalic vein.[3] Other tributaries include the subscapular vein, circumflex humeral vein, lateral thoracic vein and thoraco-acromial vein.[4] It terminates at the lateral margin of the first rib, at which it becomes the subclavian vein.[1]

It is accompanied along its course by a similarly named artery, the axillary artery, which lies laterally to the axillary vein.[5]
