“…This discrepancy is most likely related to the postural differences between humans and canids. In the human literature, internal vertebral venous plexus and intervertebral vein varices are more frequently reported to affect the lumbar region than the cervical region …”

“…In the human literature vascular abnormalities of the vertebral column are considered a rare but significant cause of myelopathy and radiculopathy . There are several studies and case reports describing a number of different vascular pathologies, including abnormal enlargements (frequently referred to as varices) of the internal vertebral venous plexus and/or intervertebral veins.…”

In humans, abnormalities of the vertebral venous system are considered rare but significant causes of radiculopathy and myelopathy. Published information on abnormalities of the canine vertebral venous system is currently lacking. Aims of this retrospective descriptive study were to characterize magnetic resonance imaging (MRI) abnormalities of the vertebral venous system in a population of sighthounds, report prevalence of vertebral venous system abnormalities within that population and explore possible clinical significance. Our hospital database was searched over the period of 2002-2013 for sighthounds with MRI studies of the vertebral column. Medical records and MRI studies for included dogs were retrieved and findings were recorded by a single observer. A total of 92 sighthounds were sampled. Eleven cases (prevalence 12%) showed abnormal enlargement of the internal vertebral venous plexus (10/11 unilaterally, 1/11 bilaterally), external vertebral venous plexus (7/11 cases unilaterally), and/or intervertebral veins (8/11 unilaterally, 2/11 bilaterally, and 1/11 unilaterally and bilaterally at different sites). The majority of the abnormalities were right sided and the most common location for abnormalities was C6/7. Of the 11 cases, nine did not have a definitive diagnosis. Seven of those nine cases had an abnormality in a neuroanatomical localization that could wholly or partly explain the clinical signs. Findings indicated that, while the prevalence of vertebral venous system abnormalities was low in this sample of sighthounds, the majority of dogs with these abnormalities had clinical signs that matched the location of the abnormalities. Further prospective research is needed to investigate potential underlying aetiologies for vertebral venous system abnormalities in dogs and clarify their clinical significance.

“…T he two most common etiologies of back pain and radiculopathy are herniation of the nucleus pulposus and degenerative changes of the spine and neuroforamen 1 . Of the myriad causes of nerve compression that lead to radiculopathy, vascular etiologies remain among the most infrequent, with an estimated prevalence of only five to ten per million cases of radiculopathy 2 .…”

“…Of the myriad causes of nerve compression that lead to radiculopathy, vascular etiologies remain among the most infrequent, with an estimated prevalence of only five to ten per million cases of radiculopathy 2 . In contrast to arteriovenous malformations, which are subdural and more commonly congenital, spinal dural arteriovenous fistulas (SDAVFs) are dural and are often acquired and/or traumatic in origin 1,3 . SDAVFs present mostly in males (male:female ratio of 5:1) in their fifties and sixties 4,5 .…”

The potential for a missed diagnosis is particularly important as many partial discectomy procedures are performed at small surgical centers with limited blood products available and no vascular surgeon on staff. For patients with preoperative magnetic resonance imaging (MRI) that is suggestive of vascular malformations (T2 hyperintensity in the lower spinal cord and conus medullaris), we recommend that MR angiography be performed as a secondary diagnostic evaluation. MR angiography has a 95% positive predictive value for specifically diagnosing an arteriovenous fistula.
