The Onyx Liquid Embolic System: Another Chance in the Management of Peripheral Bleeding

Abstract

Ethylene vinyl alcohol or Onyx copolymer (Medtronic) is an embolization agent increasingly used in peripheral interventional radiology. The Onyx Liquid Embolic System (LES) offers a liquid, non-adhesive, non-absorbable, injectable and permanent embolic agent with an indication for neuro-interventional procedures. Due to its physical properties, Onyx has more embolic predictability than other currently available liquid agents and seems to have good potential in endovascular bleeding management, especially for patients with coagulopathies or anti-coagulation therapy. The aim of this brief review is to analyze the advantages of Onyx in the emergency setting on the basis of evidence in the current literature.
