چکیده
BACKGROUND N-butyl 2-cyanoacrylate (NBCA) remains the standard embolic agent for spinal dural arteriovenous fistula (SDAVF) treatment. Treatment of SDAVF with ethylene-vinyl alcohol copolymer (Onyx, ev3-Covidien, Irvine CA, USA) is currently not well established. Although several cases have reported the use of Onyx to embolize an intracranial dural arteriovenous fistula using a dual-lumen microballoon catheter, Onyx embolization of an SDAVF using a dual-lumen microballoon catheter has not been reported. CASE DESCRIPTION We treated a 57-year-old man with an SDAVF using a dual-lumen microballoon catheter and buddy wire technique to perform transarterial Onyx embolization via the left sixth intercostal artery. CONCLUSIONS Onyx embolization using a dual-lumen microballoon catheter was effective. Furthermore, the buddy wire technique was useful for providing rigid support of the microcatheter in a narrow and tortuous intercostal artery.

BACKGROUND Dural arteriovenous fistulas are vascular malformations with variable clinical symptoms that range in severity from completely asymptomatic to seizures, dementia, loss of vision and intracranial hemorrhage. Historically, surgical obliteration was the treatment of choice but, more recently, endovascular embolization has become the first-line treatment. The liquid embolic agent Onyx (e...

We report our experience using Onyx for embolization of dural arteriovenous fistula (DAVF) under dual lumen balloon catheter flow arrest. Transfemoral cerebral angiography revealed a superior sagittal sinus (SSS) DAVF that was supplied via multiple branches of the external carotid arteries, the right anterior cerebral arteries, and the meningeal branches of the internal carotid artery. There wa...

Dural arteriovenous fistula (DAVFs) induced by trauma in the superior sagittal sinus (SSS) are rare and difficult to treat because of their unique midline location, multiplicity of arterial feeders, and critical venous drainage. We report a case of an endovascular treatment using dual lumen balloon microcatheter on a patient with post-traumatic SSS DAVF. By the use of dual lumen Scepter balloon...

Superior sagittal sinus (SSS) dural arteriovenous fistulas (DAVF) are rare and present unique challenges to treatment. Complex, often bilateral, arterial supply and involvement of large volumes of eloquent cortical venous drainage may necessitate multimodality therapy. We report a case of a DAVF of the SSS in a patient who presented uniquely with increasing dizziness and disequilibrium who was ...

relatively new embolic material consisting of ethylene vinyl alcohol polymer dissolved in dimethyl sulfoxide (DMSO) that is mainly used for embolization of a brain arteriovenous malformations (AVM) (1-4). The solidification of Onyx occurs in an ‘outside-in’ precipitation process which often allows better forward penetration than n-butyl cyanoacrylate (NBCA) (2). However, experiences of using On...
