Common iliac vein

A vein that is formed by union of the external and internal iliac veins at the brim of the pelvis and passes upward to the right of the fifth lumbar vertebra where it unites with its fellow of the opposite side to form the inferior vena cava.

The noun has one meaning:

Meaning #1: formed by the internal and external iliac veins; unites with its fellow from the opposite side of the body to form the inferior vena cava

Vein: Common iliac vein
Veins of the abdomen and lower limb - inferior vena cava, common iliac vein, external iliac vein, internal iliac vein, femoral vein and their tributaries. The aorta and its bifurcation (unlabeled) appear in red.
Abdominal portion of the sympathetic trunk, with the celiac and hypogastric plexuses. (Common iliac vein labeled at lower right.)
Latin	vena iliaca communis
Gray's	subject #173 677
Drains from	pelvis and lower limbs
Source	external iliac veins and internal iliac veins
Drains to	inferior vena cava
Artery	common iliac arteries

In human anatomy, the common iliac veins are formed by the external iliac veins and internal iliac veins and together, in the abdomen at the level of the fifth lumbar vertebrae^[1], form the inferior vena cava. They drain blood from the pelvis and lower limbs.

Both common iliac veins are accompanied along their course by common iliac arteries.
