Clinical Outcome in Patients With Spinal Dural Arteriovenous Fistulas

Summary: Spinal dural arteriovenous fistulas (SDAVFs) are the most common vascular disorder of the spine and account for approximately 70% of spinal vascular malformation.They are a rare pathology with an excepted incidence of only 5-10 new cases per million inhabitants per year. Most fistulas are found in the thoracolumbar region and > 80% of all SDAVFs are located between T6 and L2, whereas the cranio-ce...
