The veins do not follow the artery. The veins that drain the anterior abdominal wall pass from the umbilicus in a radiate manner, resembling the spokes of bicycle wheel. They pass to the great saphenous vein below the umbilicus and to the lateral thoracic vein from where they reach the axillary vein above the umbilicus. Some drain via the ligamentum teres to the portal vein and hence may become distended in portal obstruction leading to formation of the so-called caput medusae and also a distended thoraco-epigastric vein (inguino-axillary vein) at the mid-clavicular line.
