 We describe a case of dural arteriovenous fistulas (DAVFs) involving the superior sagittal sinus (SSS) successfully treated with stent placement for an occluded sinus and transarterial embolization.  A 61-year-old man who had been treated with anticoagulation for a known SSS thrombosis presented with a sudden onset of headache. CT scan revealed an intraventricular hemorrhage and cerebral angiography revealed DAVFs involving the SSS which had severe venous congestion and sinus occlusion. We treated this case with a staged endovascular approach which consisted of stent placement for the occluded sinus and transarterial intravenous embolization resulting in complete eradication of DAVFs.  Recanalization of an occluded sinus by stent placement can reduce venous congestion and transarterial intravenous embolization can obliterate dural arteriovenous shunts. This staged strategy is feasible and should be considered a first option of treatment, especially for DAVFs which presented with intracranial hemorrhage and aggressive venous hypertension. </jats:p
