[The results of the embolization of arteriovenous malformations in the spinal cord].

Embolization of arteriovenous malformations (AVM) of the spinal cord on different levels was performed in 30 patients whose ages ranged from 6 to 58 years. Fragments of a hemostatic sponge "spongostan" and polyvinyl acetate crumbs measuring 0.2-0.5 mm in size were used as the thrombogenic agents. In 2 children with aneurysm of cervical localization the afferent vessels were occluded by means of a separable balloon after F. A. Serbinenko's method. The AVM were located on the cervical level of the spinal cord in 4, on the thoracic level in 20, and on the lumbar level in 6 patients. After embolization and occlusion of the AVM with the balloon the neurological status improved considerably in 20 patients with various degree of affection of the spinal cord, even those with paraplegia and tetraplegia. Social activity was restored after the endovascular interventions and some patients were able to resume work. A mild improvement occurred after embolization in 6 patients and the neurological status did not change in 3 patients. The condition of one patient grew worse after repeated embolization due to thrombosis of the ascending branch of Adamkiewicz's artery.
