Common iliac vein, formed by the external and internal iliac veins, drains into the inferior vena cava

Deep circumflex iliac vein, formed by the union of the venae comitantes of the deep iliac circumflex artery, and joins the external iliac vein

External iliac vein, terminates at the common iliac vein, drains the femoral vein
