| vertebral venous plexus | Any of four interconnected venous networks surrounding the vertebral column; anterior external vertebral venous plexus, the small system around the vertebral bodies; posterior external vertebral venous plexus, the extensive system around the vertebral processes; anterior internal vertebral venous plexus, the system running the length of the vertebral canal anterior to the dura; posterior internal vertebral venous plexus, the system running the length of the vertebral canal posterior to the dura; the latter two constitute the epidural venous plexus.

| chronic venous insufficiency | <cardiology> A condition in which the vein do not channel the flow of blood adequately. most often this condition is seen in the veins of the lower extremities. Symptoms include leg swelling, leg pain and muscle cramps. This condition can predispose to venous thrombosis. (27 Sep 1997) |
