Veins of the vertebral column (English)

Spinal veins form internal and external vertebral venous plexuses along the vertebral column. Each of these plexuses can be further divided into an anterior and a posterior plexus. Within the trabecular bone of the vertebral body are the basivertebral veins. These veins emerge on the posterior aspect of each vertebral body and drain into the anterior external and anterior internal venous plexuses. The intervertebral veins are located on the superior surface of the pedicle of each vertebra and drain regions of the spinal cord and vertebral plexuses. The intervertebral veins travel through the intervertebral foramina of the vertebral column to drain into the vertebral veins of the neck and segmental veins of the trunk.
