External iliac vein
The external iliac veins are large veins that connect the femoral veins to the common iliac veins. Their origin is at the inferior margin of the inguinal ligaments and they terminate when they join the internal iliac veins (to form the common iliac veins).
Both external iliac veins are accompanied along their course by external iliac arteries.
Significant tributaries of the external iliac vein
The inferior epigastric veins drain into the external iliac veins.
