Vein Iliac External

The external iliac vein (lat. vena iliaca externa) is a large vessel of the venous system of the pelvis and lower limb.

The external iliac vein is formed by the confluence of the anterior and posterior femoral veins at the level of the inguinal ligament. Next, the external iliac vein passes upward and laterally, where at the level of the intervertebral disc between the L5 and S1 vertebrae it merges with the internal iliac vein, forming the common iliac vein.

The external iliac vein receives venous blood from the muscles and skin of the lateral thigh, as well as the gluteal region. Main tributaries: superficial epigastric vein, deep epigastric vein, genital veins.

Thus, the external iliac vein plays an important role in the outflow of blood from the lower limb into the systemic circulation.
