[Transarterial embolization for cranial vault dural arteriovenous fistula: a case report]

A 70-year-old man presented with a rare case of a dural arteriovenous fistula (dAVF) at the cranial vault manifesting as headache. Cerebral angiography disclosed that multiple feeding arteries were immediately draining into the right parietal cortical vein without communication to the superior sagittal sinus, and this dAVF was classified as Borden type III and Cognard type IV. Transarterial embolization was performed using particles of polyvinyl alcohol and glue of n-butyl 2-cyanoacrylate. After embolization, the dAVF had completely disappeared and the patient was discharged without any symptom. Angiogram one year after embolization showed no recanalization of dAVF. Transarterial glue embolization is a safe and effective treatment of dAVF with cortical venous reflux.
