Classification of spinal cord vascular malformations.

Through the aid of developments in the neuroradiological sciences, great attention has been given to the diagnosis and treatment of vascular malformations of the spinal cord. Some of these are congenital, such as intramedullary vascular malformations and arteriovenous fistulae supplied by the spinal cord. Others are rather frequent and appear in old age. Due to their poor prognosis when not treated, precise determinations and sufficient knowledge are of the utmost importance.
