Effects of artificially induced spinal cord compression on the canine cervical internal vertebral venous plexus: comparative evaluation of computed tomographic venography and digital subtraction venography

The internal vertebral venous plexus (IVVP) is a vascular network located along the vertebral canal. The present study was designed to assess variation in morphology of the cervical IVVP under experimental acute spinal cord compression in dogs. Experimental spinal cord compression was induced in 9 a...

Experimental spinal cord compression was induced in 9 adult dogs at C3/4 vertebral canal level using a modified angioplasty balloon catheter technique. Dogs were evaluated prior to, during and post spinal cord compression using vertebral intraosseous digital subtraction venography (DSV) and computed tomographic (CT) venography.
