In human anatomy, the internal thoracic vein (previously known as the internal mammary vein) is a vessel that drains the chest wall and mamma, a term used for breast in anatomy.
Bilaterally, it arises from the superior epigastric vein, accompanies the internal thoracic artery along its course and terminates in the brachiocephalic vein.
