Pathology

  • They are classified as type 1 spinal arteriovenous malformations (AVMs)
  • They develop between the radicular artery and vein
  • They are either extradural or intradural
  • They cause congestion of venous outflow and ischaemia of the spinal cord
  • Myelopathy develops from venous hypertension
  • They are usually thoracolumbar: 2% are cervical and 4% are sacral
