Bilateral variation in the origin of suprascapular artery

Suprascapular artery which is usually a branch of thyrocervical trunk, in the present case arose from the first part of the axillary artery, on both sides. It then it passed obliquely behind the clavicle and then between the trunks of brachial plexus to reach the suprascapular notch, where it was accompanied by the suprascapular nerve and both together passed beneath the transverse scapular ligament and took part in the anastomosis around the scapula.
