|Common iliac vein|
Abdominal portion of the sympathetic trunk, with the celiac and hypogastric plexuses. (Common iliac vein labeled at lower right.)
|Latin||Vena iliaca communis|
|Pelvis and lower limbs|
|External iliac veins and internal iliac veins|
|Inferior vena cava|
|Common iliac arteries|
In human anatomy, the common iliac veins are formed by the external iliac veins and internal iliac veins. The left and right common iliac veins come together in the abdomen at the level of the fifth lumbar vertebra, forming 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.
