It wasn't possible for me to do the injection preparations which would have answered the question to which other veins of the neck the cervical epidural veins primarily relate.
Did you make observations on this point?
Occasionally, it is a single vein rather than a venous plexus.The venous plexus of hypoglossal canal also known as plexus venosus canalis nervi hypoglossi, circellus venosus hypoglossi and rete canalis hypoglossi is a small venous plexus around the hypoglossal nerve that connects with the occipital sinus, the inferior petrosal sinus and the internal jugular vein.
The cervical epidural veins are connected superiorly to the suboccipital plexus and to the anterior condyloid vein, which is in continuity with the inferior petrosal sinus. Laterally, the cervical epidural veins are connected to the vertebral plexus that surrounds the vertebral artery in the transverse foramen
Veins emerging from the condylar canal were indeed seen to often connect to internal jugular veins. Still, I saw connections to veins of the lateral, posterior, and anterior condylar channel as well - but couldn't determine their final destination.
The complexity of the suboccipital vein plexus and its changeable ending up in the deep cervical veins (French: posterior jugular veins) made things the most intricate.
