Inhuman anatomy, thesuperior epigastric veins are two or more[1]venae comitantes which accompany eithersuperior epigastric artery before emptying into theinternal thoracic vein. They participate in the drainage of the superior surface of thediaphragm.
The superior epigastric vein originates from theinternal thoracic vein.[2]: 193 The superior epigastric veins first run between the sternal margin and the costal margin of the diaphragm, then enter therectus sheath.[3] They run inferiorly, coursing superficially to the fibrous layer forming the posterior leaflet of the rectus sheath, and deep to therectus abdominis muscle.[4]: 211
The superior epigastric veins arevenae comitantes of thesuperior epigastric artery,[5] and mirror its course.[3]
The superior epigastric veins participate in the drainage of the superior surface of the diaphragm.[3]
The superior epigastric veins drain into theinternal thoracic vein.[6][3]
