Dural Arteriovenous Fistulae (DAVF)
Treatments
Treatment for dural arteriovenous fistulae (DAVF) depends on the blood vessels involved. Endovascular techniques, which are minimally invasive procedures that are performed through the blood vessels, have been developed to safely treat DAVFs.
An approach, called embolization, reduces blood flow to the DAVF by obstructing surrounding blood vessels. During this procedure, the DAVF is filled with specially designed coils, glues or spheres that plug the vessels.
Some fistulas can't be completely blocked with embolization and may require surgery to disconnect or close them. In some cases, doctors may try to close the fistula with what's called stereotactic radiosurgery or the Gamma Knife.
