Liquid embolics are an important tool for the interventional radiologist, particularly Onyx. Its use as a primary or accessory embolization agent in peripheral intervention has increased substantially in recent years, with uses including peripheral vascular, GI, and GU pathologies {1,2}.
Onyx exists as an ethylene vinyl alcohol plastic polymer, which must be dissolved in DMSO to remain in liquid form. When deployed, blood displaces the DMSO, allowing the polymer to solidify from the outside in, filling the vessel lumen without adhering to the vascular endothelium {3,4}. Though currently only approved for the treatment of cerebral vascular lesions, these physicochemical properties also make it safe for use in a variety of peripheral interventions, allowing for progressive solidification, cohesion, high vascular penetration, low reflux risk, and excellent biocompatibility {5,6}. Additionally, this offers the ability to embolize difficult to cannulate vessels, efficient and expedient embolization, and embolization of very small feeder vessels {7}.
