Endovascular Treatment of a Dural Arteriovenous Fistula of the Transverse Sinus by Recanalisation, Angioplasty and Stent Deployment

Abstract

We report the endovascular treatment of a 40- year-old woman with bilaterally thrombosed transverse sinuses and a dural arteriovenous fistula (DAVF) causing cortical venous reflux by recanalization, angioplasty and stent deployment of the occluded sinus segment followed by occlusion of the DAVF by stent deployment in the fistulous segment. By recanalization of the occluded sinus we re-established normal anterograde venous drainage and eliminated the venous hypertension and cortical venous reflux. After the procedure, the patient was treated with aspirin and clopidogrel for three months. A follow- up examination showed total occlusion of the DAVF, patency of the sinus and a complete resolution of the clinical symptoms.
