Seven patients presented with intracranial hemorrhage due to arteriovenous dural fistula. Six patients showed intracerebral hemorrhage combined with subdural hematoma and intraventricular hemorrhage in one case respectively, and one patient had infratentorial subarachnoid hemorrhage. Location of the fistulae was frontobasal (n=2), tentorium (n=2), transverse sinus (n=2), and superior sagittal sinus (n=1). Angiography revealed reflux into cortical veins in all cases. Therapy was surgery in both cases with fistula of the anterior cranial fossa with good results. An endovascular intraarterial therapy was performed in a case with circumscribed fistula of the superior sagittal sinus, this patient developed a second dural fistula during follow-up. Two patients with tentorial fistulae had primary endovascular treatment complicated by infarction of both thalami in one case and a recurrence of the fistula in the other. In the last case the fistula was closed by surgery. Out of two patients with widespread fistulae of the transverse sinus one made a good clinical recovery and the other remained unchanged. In the first case definite closure of a remnant of the fistula was refused, in the second no further therapy was recommended.
