Transcondylar Approach for Dural Arteriovenous Fistulas of the Cervicomedullary Junction

Background Spinal dural arteriovenous fistulas are abnormal arteriovenous connections on the surface of the dura. The site of the fistula is most commonly in the thoracic and lumbosacral regions and they are rarely located in the cervical region. Cases The patients had two asymptomatic dural arterio...

Description
Summary:Background Spinal dural arteriovenous fistulas are abnormal arteriovenous connections on the surface of the dura. The site of the fistula is most commonly in the thoracic and lumbosacral regions and they are rarely located in the cervical region. Cases The patients had two asymptomatic dural arteriovenous fistulas of the cervicomedullary junction fed by the left posterior meningeal artery and draining to the dilated coronal venous plexus and the radiculomedullary vein. Results The lesions were successfully treated by surgical interruption of the intrathecal vein with coagulation via a suboccipital transcondylar approach and a condylar fossa approach. Both patients left the hospital without significant deficits. Conclusions We recommend that dural arteriovenous fistulas in the cervical region be surgically treated.
