BACKGROUND AND PURPOSE: Dural arteriovenous fistulas (DAVFs) with direct antegrade sinus drainage have a benign natural history but bruit can be disabling. Disconnection of the draining sinus is considered curative. We present the treatment results of 14 patients with a dural arteriovenous fistula with antegrade sinus return with emphasis on functionality of the involved sinus and the need for sinus patency. MATERIALS AND METHODS: Between January 2009 and January 2018, 14 patients with a DAVF with direct antegrade sinus drainage were treated in our institution. There were two men and 12 women (1: 6) with a mean age of 61 years (median 61, range 43-78). Clinical presentation was unbearable pulsatile bruit in all cases. Thirteen were draining in the sigmoid or transverse sinus and one drained into the inferior petrosal sinus. RESULTS: Twelve of 14 (86%) patients had a draining sinus non-functional for the brain. In ten of these 12 patients the sinus was occluded with liquid embolic or coils. In the two patients with a functional sinus, the fistula was successfully occluded without occluding the sinus. One patient with inferior petrosal sinus drainage required transvenous embolization. There were no permanent adverse events of treatment. CONCLUSIONS: Patients with DAVFs with direct antegrade sinus drainage were cured using a strategy of endovascular transarterial and transvenous embolization. Most patients had a non-functional sinus that could be occluded for cure.
