Transvenous Endovascular Treatment of a Dural Arteriovenous Fistula Involving an Isolated Segment of the Superior Sagittal Sinus Through Recanalization of the Occluded Sinus

A 75-year-old man presented with bilateral frontal hematomas owing to a dural arteriovenous fistula involving an isolated segment of the superior sagittal sinus. After an unsuccessful attempt of transarterial endovascular embolization of the dural arteriovenous fistula, the fistula was occluded using a transvenous approach through recanalization of the occluded superior sagittal sinus.
