Although its etiology is not fully elucidated, there are hypotheses on dural insufficiency in the literature. Pulsatile tinnitus and headache are the most common symptoms in the clinical course from asymptomatic cases to severe neurological damage. 10-15% of all intracranial vascular shunts are dural artery-venous shunts, and transverse-sigmoid sinus junction DAVFs constitute most of these pathologies. Venous reflux is the most important factor determining mortality and morbidity. Neurological dysfunction occurs due to intracranial hemorrhage secondary to venous reflux. Treatment modalities are conservative follow-up, arterial or venous embolization, microsurgery, radiosurgery, and combinations of these modalities.
