Objective: We report a useful technique for transarterial embolization with liquid material using a 4.2Fr Fubuki catheter as an intermediate catheter.Materials and Methods: Five consecutive cases of dural arteriovenous fistula (dAVF) of the transverse/sigmoid sinus with cortical venous reflux were treated by transarterial embolization (TAE) using a 4.2Fr Fubuki catheter as an intermediate catheter inserted into the middle meningeal artery (MMA). With this support, the microcatheter could be advanced to the shunt point and the shunt was occluded successfully with N-butyl cyanoacrylate (NBCA). All cases were managed using the same strategy. In all cases, NBCA was injected into the venous portion of the shunt and complete obliteration of the shunt was achieved in one session. We report in detail the illustrative case of a 71-year-old man who presented with visual symptoms and speech disturbance and was found to have a Borden type III dural arteriovenous fistula in the left transverse sinus.Conclusion: With its highly flexible distal tip and hydrophilic coating, the 4.2Fr Fubuki catheter was found to be useful in performing TAE of dAVFs via the MMA.
