Intervertebral veins

Intervertebral veins are a group of veins in the human body that drain the vertebral column. They are part of the vertebral venous plexus, a network of interconnected veins that run along the length of the vertebral column.

Anatomy

The intervertebral veins are located in the intervertebral foramina, the openings between the vertebrae through which the spinal nerves exit the spinal column. They are paired, with one vein on each side of the foramen.

The intervertebral veins drain into the vertebral veins, which in turn drain into the brachiocephalic veins and ultimately into the superior vena cava, returning blood to the heart.

Function

The primary function of the intervertebral veins is to drain blood from the vertebral column. They also play a role in the venous return from the spinal cord and the meninges, the protective coverings of the brain and spinal cord.

Clinical significance

Due to their location, the intervertebral veins can be affected by conditions that impact the vertebral column, such as vertebral disc herniation or spinal stenosis. They can also be involved in the spread of cancer from the vertebral column to other parts of the body.
