| Abstract |
|
Transvenous coil embolization has been successfully applied for the treatment of cerebral dural arteriovenous fistulae.
Unfortunately, the technique can not be applied in cases of poor or absent venous access route to the fistula, the situation of which is not uncommon. Transarterial embolization can be performed as an alternative method.
However, the method usually ended in partial embolization of the fistulae because of the multiplicity of the dural feeders and anfractuosity of the feeders. Use of liquid embolic material, such as glue in transarterial embolization generally regarded as not conventional. Recently we experienced a successful embolization using a newly introduced liquid embolic material, Onyx in a case of transverse-sigmoid sinus dural arteriovenous fistula which was failed to be embolized with transvenous approach. |
