Spinal Arteriovenous Malformations

Abstract

Clinical signs and symptoms of spinal arteriovenous malformation (AVM) have different characteristics according to the type of the AVM. Various classifications have been proposed for this complex lesion [1-3]; we use our own modified classification just to simplify our work-up discussion. We divide the spinal arteriovenous (AV) malformations by their fistula or nidus locations into dural, perimedullary, and intramedullary type and by fistulas or true malformations. Authors identify the dural AV fistulas (dAVF) (Fig. 28.1), perimedullary AV fistulas (AVF) (Fig. 28.2), and spinal cord true AV malformation (AVM) that is either juvenile-type AVM or glomus-type AVM.

Spinal arteriovenous malformation: A case report and review of literature

“…The cervico-thoracic location in this case varies from common sites of AVM reported in literature. [ 16 ] González described the lower thoracic and thoracolumbar regions as the common site of occurrence. [ 16 ] Rodesch et al noted either the cervical or thoracic locations without extensions between the two regions of the spinal cord.…”

[ 16 ] Rodesch et al noted either the cervical or thoracic locations without extensions between the two regions of the spinal cord. [ 17 ] The presentation of tetraparesis from AVM associated with abnormal cord features spanning from C2 to T4 ultimately worsens the prognosis.…”
