Abstract
We report a case of dural arteriovenous fistulae (AVF) of the transverse sigmoid sinus associated with sinus occlusion stenosis. A 72-year-old male was presented who had had repeated episodes of intraventricular hemorrhage. We failed to obliterate the fistulae by transarterial embolization due to the recruitment of other feeding vessels and recanalization of embolized vessels. The transvenous embolization or resection of dural AVF seemed to be dangerous since the venous drainage system was not compensated by cortical veins. Although balloon angioplasty from the stenotic sinus gave temporary relief of venous congestion, this case, in the end, had an unfavorable outcome. We feel, this suggests that the treatment of dural AVF without compensatory venous drainage system can be very difficult.
