[TA]
formed by the union of the external and internal iliac veins at the brim of the pelvis and passes upward posterior to the internal iliac artery to the right side of the body of the fifth lumbar vertebra where it unites with its fellow of the opposite side to form the inferior vena cava; the left common iliac vein is submitted to a pulsating compression by the right common iliac artery against the vertebral column that may result in partial obstruction of the vein.

common iliac vein

one of the two veins that are the sources of the inferior vena cava, formed by the union of the internal and external iliac veins, ventral to the sacroiliac articulation. Each common iliac vein receives the iliolumbar and, in some individuals, the lateral sacral veins. The left common iliac vein also receives the middle sacral vein. Neither of the common iliacs contains valves. Compare external iliac vein, internal iliac vein.

common iliac vein

The vein accompanying the common iliac artery; it is formed by the union of the external and internal iliac veins, and it ends by merging with the opposite common iliac vein to form the inferior vena cava. The right iliac vein is shorter than the left. Tributaries of the common iliac vein include the iliolumbar, lateral sacral, and median sacral veins.
