They forms venous anastomoses through intervertebral foramina by way of intervertebral veins at all vertebral levels. [2]Around the foramen magnum, they form a dense venous network with the vertebral veins, sigmoid sinuses, occipital sinuses, the basilar plexus, the condyloid emissary veins, and the rete canalis hypoglossi.
The intervertebral veins accompany the spinal nerves through the intervertebral foramina to drain the internal vertebral venous plexuses into the external vertebral venous plexuses. [1] They drain (in craniocaudal sequence) into vertebral vein, intercostal veins, lumbar veins, and lateral sacral veins. Upper posterior intercostal veins may ...
The posterior longitudinal ligament is narrower and less firmly attached to vertebral bodies (compared to over the intervertebral discs) so as to allow for passage of the basivertebral veins. [3] The basivertebral veins are the main tributaries of the internal vertebral venous plexus. [4]

This plexus ends in a single trunk, which emerges from the transverse foramina of the sixth cervical vertebra, and opens at the root of the neck into the back part of the innominate vein near its origin, its mouth being guarded by a pair of valves. On the right side, it crosses the first part of the subclavian artery.
The Batson venous plexus (Batson veins) is a network of valveless veins in the human body that connect the deep pelvic veins and thoracic veins (draining the inferior end of the urinary bladder, breast and prostate) to the internal vertebral venous plexuses. [1]

Ultimately, this plexus is able to send and receive information from the veins and sinuses inside the brain. The external vertebral venous plexuses is also available for the internal vertebral venous plexus to communicate with. [2] Anterior spinal veins fall into the intradural network of the vertebral venous system. The intradural network ...
