The fistula was found in the upper thoracic spine in 2 cases, in the lower thoracic (T7–Th12) in 11 cases, and in the lumbar spine in 4 cases.

Postoperative complications occurred in 4 patients (24%), two of them (12%) required revision surgery for epidural hematoma. The success rate was 94%; one patient required revision surgery for recurrent SDAVF.

Introduction  \nSpinal dural arteriovenous fistulas (SDAVFs) classified by Spetzler as intradural dorsal arteriovenous fistulas [1] are the most common vascular malformation of the spinal cord. They are acquired and constitute approximately 80% of vascular malformations in the spinal canal [2] . SDAVFs are rare pathology with an incidence of 5–10 new cases per million per year. Most of them are located in the thoracolumbar region of the spine and they mostly occur in older and middle aged men. SDAVFs are rare in the sacral region (4%) and rarely may present as multi-level fistulas (2%) [1,2] .  \nThe essence of the disease is a direct connection between the meningeal arterial branch and the venous coronary plexus of the spinal cord.
