Objective: We report a case of superior sagittal sinus (SSS) dural arteriovenous fistula (dAVF) treated with transarterial Onyx injection under flow control using two balloon guiding catheters and a dual-lumen balloon microcatheter.

Case Presentation: A 54-year-old man previously diagnosed with SSS dAVF with cortical venous reflux at 4 years prior, who did not request treatment as he was asymptomatic. During follow-up, he developed right temporal lobe subcortical hemorrhage and showed an occlusive change in venous drainage. We performed transarterial Onyx injection with assistance using multiple balloons placed in the bilateral external carotid and right middle meningeal arteries. Using this technique, we were able to sufficiently fill the proximal part of the venous drainage with Onyx and achieved complete obliteration. No treatment-related complication was observed, and follow-up angiography performed at 8 months after the treatment showed no recurrence.

Conclusion: Multiple balloon-assisted transarterial Onyx embolization is useful for adequate fillings of shunt and the proximal part of the venous drainage.
