External iliac vein

  • The external iliac vein (latin: vena iliaca externa) is a large vein formed by the femoral vein.

    The external iliac vein begins above the level of the inferior margin of the inguinal ligament. It enters the pelvis via the vascular lacuna and then ascends medially along the medial side of the psoas major. Reaching the sacroiliac joint, the external iliac vein unites with the internal iliac vein to form the common iliac vein.

    Along their course, the external iliac veins are accompanied by the external iliac arteries.

    The external iliac vein receives the inferior epigastric vein and the deep circumflex iliac vein.

    The external iliac veins drain blood from the muscles and skin in the lower abdominal wall.
