Embolization of spinal cord arteriovenous malformations with an ethylene vinyl alcohol copolymer dissolved in dimethyl sulfoxide (Onyx liquid embolic system). Report of two cases

J Neurosurg. 2000 Oct;93(2 Suppl):304-8. doi: 10.3171/spi.2000.93.2.0304.


In this paper the authors describe the first use of a new liquid embolic agent (Onyx) to treat spinal cord arteriovenous malformations (AVMs). Because its properties make it more predictable to use than currently available liquid agents, the authors believe that this material has great potential in the endovascular management of both spinal cord and brain AVMs. This very promising agent merits further clinical study.
