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.","thumbnailUrl":"https://sni-digital-videos.s3.amazonaws.com/articles/351cbd9e-350f-42db-9219-0103aa4f8ee1/featured/hero-1782420816382.png","publishDate":"2017-08-01T00:00:00.000Z","doi":"10.4103/sni.sni_193_17","categories":["Spine","Case Report"],"fullTextUrl":"http://surgicalneurologyint.com/wp-content/uploads/2017/08/8525/SNI-8-166.pdf"}
