We studied 5 patients with retrograde venous drainage of the dural arteriovenous fistulas (DAVFs) with regard to clinical features and treatment. All the cases were examined by detailed angiography and magnetic resonance (MR) imaging before treatment. Two patients presented with intracerebral hemorrhage and 3 patients exhibited progressive neurological deficit. In all patients, large varices were recognized. After transarterial embolization, 4 patients were treated with direct surgery consisting of interruption of the draining vein at the point of exit from the dural wall of the sinus. In these procedures, it is important that the refilling normal venous return was preserved.
