It affects all of the vessels: very small blood vessels (capillaries), medium-size blood vessels (arterioles and venules), or large blood vessels (arteries and veins).

Lumbar veins lumbar veins on the left pass behind the abdominal aorta to reach the inferior vena cava and "all" lie behind the sympathetic trunks. The iliolumbar veins join the common iliac veins.

They are four in number and accompany the four lumbar arteries, with the vein lying superior to the artery (the same arrangement as in the intercostal neurovascular bundles). The first and second lumbar veins usually join the ascending lumbar vein rather than the
