The external iliac vein is the continuation of the common femoral vein. The common femoral vein changes its name at the lower border of the inguinal ligament at the medial side of the termination of the external iliac artery. It passes upward along the brim of the pelvis, and joins the internal iliac vein to form the common iliac vein opposite the sacroiliac synchondrosis. On the right side, the external iliac vein lies to the medial side of the artery but soon passes behind it on the left side. It remains to the medial side of the artery throughout its entire course. The tributaries of the external iliac vein are the inferior epigastric and the deep circumflex iliac veins.
