Aneurysm Treatment with Liquid Embolics

During the past decade, Onyx® HD-500 (Medtronic Neurovascular, USA), a high-viscosity liquid embolic agent, has been used extensively to treat intracranial aneurysms. Preliminary experience using this relatively novel agent was rewarding in terms of high-occlusion rates and low-recanalization rates of large and wide-necked aneurysms [1, 2]. Use of Onyx HD-500 has since decreased dramatically with the increasing popularity of flow diverters as first-line treatment for complex intracranial aneurysms. Nevertheless, it remains a useful endovascular tool for select patients who are not good candidates for flow diversion because of recurrent stent-embolized aneurysms or nickel allergy.
