External iliac vein
Vena iliaca externa
Definition
The external iliac vein (v. iliaca externa), the upward continuation of the femoral vein, begins behind the inguinal ligament, and, passing upward along the brim of the lesser pelvis, ends opposite the sacroiliac articulation, by uniting with the hypogastric vein to form the common iliac vein.
On the right side, it lies at first medial to the artery: but, as it passes upward, gradually inclines behind it.
On the left side, it lies altogether on the medial side of the artery. It frequently contains one, sometimes two, valves.
Tributaries.—The external iliac vein receives the inferior epigastric, deep iliac circumflex, and pubic veins.
