These abnormal connections divert normal blood flow into veins causing increased venous pressure.
What is Dural Arteriovenous Fistula (DAVF)?
A dural arteriovenous fistula (DAVF) is an acquired abnormal connection between arteries and veins within the dura mater which lines the surface of the brain and spinal cord. These abnormal connections divert normal blood flow into veins causing increased venous pressure.
-This may lead to pain, headaches, visual symptoms, noise (bruit), and can result in bleeding or stroke.
-Neuro interventional radiologists use embolization techniques to reduce or eliminate blood flow to the DAVF using specially designed glues, spheres, or coils.
