[Morphofunctional changes in the spinal cord, its meninges and epidural structures in experimental obturation of the epidural veins of the spinal canal].

When the blood flow in the epidural veins of the spinal cord canal is stopped (performed in 24 dogs) by means of paraffin emboli, it results, at early stages, in distrophic and hypoxic changes in neurons and glial cells of the spinal cord. In 2-4 weeks these changes are substituted by certain restorative processes and in 3 months normal structure and function are restored.
