Superior epigastric vein

In human anatomy, superior epigastric veins are two or more[1] venae comitantes which accompany either superior epigastric artery before emptying into the internal thoracic vein. They participate in the drainage of the superior surface of the diaphragm.

Superior epigastric artery, internal thoracic artery and inferior epigastric artery. (Superior epigastric artery is labeled at right center, and superior epigastric vein runs with it.)

Structure

Course

The superior epigastric vein originates from the internal thoracic vein.[2]: 193  The superior epigastric veins first run between the sternal margin and the costal margin of the diaphragm, then enter the rectus sheath.[3] They run inferiorly, coursing superficially to the fibrous layer forming the posterior leaflet of the rectus sheath, and deep to the rectus abdominis muscle.[4]: 211 

The superior epigastric veins are venae comitantes of the superior epigastric artery,[5] and mirror its course.[3]

Distribution

The superior epigastric veins participate in the drainage of the superior surface of the diaphragm.[3]

Fate

The superior epigastric veins drain into the internal thoracic vein.[6][3]
