These are organized into individual comb-like repetitive structures that eventually fuse together once in the ventral median spinal fissure.

[1] These veins can infiltrate back into the ventral median spinal fissure previously mentioned by up to a few centimeters.

Next, both radicular veins travel to the epidural space by means of joining the internal vertebral venous plexuses.

For example patients that have spinal dural fistulas can experience venous hypertension caused by thrombosis of these veins.

This lack of research is due in great majority to the fact that there is no reliable method of visualizing the system in a noninvasive manner.

Although some methods such as an MRI can give off useful information, these stationary glimpses do not show the true actions that take place.
