Embolization of intracranial arteriovenous malformations with ethylene-vinyl alcohol copolymer (Onyx).
BACKGROUND AND PURPOSE Endovascular therapy of intracranial arteriovenous malformations (AVMs) is increasingly used. However, it is still under discussion which embolic material is optimal. We report our experience in the treatment of AVMs with ethylene-vinyl alcohol copolymer (Onyx). MATERIALS AND METHODS Between July 2002 and January 2008, brain AVMs were embolized with Onyx in 82 consecuti...
متن کاملTranscatheter embolization of congenital hepatic arteriovenous malformation using ethylene-vinyl alcohol copolymer (Onyx).
A male infant with high-output heart failure who had been found to have a hepatic arteriovenous malformation by ultrasound imaging was referred to our center (Department of Diagnostic and Interventional Radiology, Imam Khomeini Hospital, Tehran University of Medical Sciences, Islamic Republic of Iran) for further evaluation. Computed tomography angiography revealed a large hepat...
متن کاملTechnical feasibility and histopathologic studies of ethylene vinyl copolymer (EVAL) using a swine endovascular embolization model.
PURPOSE To study the safety, technical efficacy, and histopathology of the ethylene vinyl alcohol copolymer (EVAL) embolic mixture in an animal model. METHODS Microcatheterization of the rete was performed in 29 swine. The clinical, angiographic, and histopathologic consequences of superselective injection of the two principal embolic mixture components (EVAL and dimethyl sulfoxide [DMSO]) we...
متن کاملstudy of ethylene/vinyl acetate transformation to ethylene/vinyl alcohol copolymer by nmr and dsc
hydrolysis of ethylene-vinyl acetate copolymer in alkaline conditions using two systems of naoh/methanol and koh/isopropanol has been studied and the formation of ethylene-vinyl alcohol copolymer was systematically examined using nmr spectroscopy and dsc measurements. vinyl acetate weight percentage and the degree of hydrolysis were calculated from nmr spectroscopy and it is shown that hydrolys...
متن کاملEmbolization of a spinal dural arteriovenous fistula with ethylene-vinyl alcohol copolymer (Onyx) using a dual-lumen microballoon catheter and buddy wire technique
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 micro...
