A rare case of metachronous double spinal dural arteriovenous fistula

[2],[3],[4] Though the exact pathophysiology of DAVF remains unclear, late onset of symptoms, lack of other associated vascular anomalies, predominant occurrence in males and development of such lesions following trauma and following surgery strongly points towards an acquired etiology. [2],[3],[4],[5] Though the exact mechanism of development of metachronous DAVF as described in the present case remains controversial, chances of venous thrombosis occurring in the spinal/medullary veins or iatrogenic venous injury after surgical treatment of the original spinal DAVF appears to be the most probable etiology.
