Two unusual cases of the suprascapular artery taking origin from the internal thoracic artery instead of the thyrocervical trunk or the subclavian artery, were observed during routine dissections in the Anatomy Department of the Garyounis University, Benghazi.
In one of the cases the suprascapular artery was found superficial to the subclavian vein instead of running deep to it as expected. This makes it an extremely rare anomaly worth reporting and recording. In the literature available, the incidence of the suprascapular artery arising from the internal thoracic is found to be3 to 4% only and there is no mention of its passing superficial to the subclavian vein.
Such an unusual position of the suprascapular artery makes it vulnerable to injury in cases of fracture of the clavicle and may lead to arterio-venous fistula.
