In human anatomy, the internal thoracic vein (previously known as the internal mammary vein) is a vessel that drains the chest wall and breasts.[1]
Structure
Bilaterally, the internal thoracic vein arises from the superior epigastric vein, and accompanies the internal thoracic artery along its course.[1] It drains the intercostal veins, although the posterior drainage is often handled by the azygous veins.[1] It terminates in the brachiocephalic vein.[2] It has a width of 2-3 mm.[3]
Variations
Bifurcation of each internal thoracic vein is common. The left internal thoracic vein may bifurcate between ribs 3-4 or remain as a single vein.[4] The right internal thoracic vein may bifurcate between ribs 2-4 or remain as a single vein.[4]
Function
The internal thoracic vein drains the chest wall and the breasts.[1]
