Intradural extramedullary spinal arterio-venous malformations fed by the anterior spinal artery.
There is a small group of spinal arteriovenous malformations which differ from all of the others. They receive their blood supply from the anterior spinal artery but are located outside of the spinal cord and its pia mater. Six such malformations from our series of 150 spinal arteriovenous malformations 1,4 are reported. They differ in their clinical manifestations from the others. They can be extirpated with improvement in the patient's clinical manifestations.
