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]
