The embolization of vascular malformations of the spinal cord with low-viscosity silicone rubber.
Development of the low-viscosity silicone rubber has made possible the successful embolization and complete obliteration of 9 out of 11 vascular malformations of the spinal cord treated with this material. The procedure is particularly useful in patients where the malformation is fed by a limited number of posterior radicular feeders without any supply from the anterior spinal artery. One patient with a supply from the anterior spinal artery. One patient with a supply from both anterior and posterior feeders was successfully embolized after a temporary occlusion of the anterior spinal radicular feeder. Seven patients out of 11 embolized with silicone rubber showed a clinical improvement of their signs and symptoms.
