Liquid embolic agents are materials that are injected as a liquid and solidify to obstruct the blood flow. These agents can be made of various materials such as ethylene vinyl alcohol (EVOH), cyanoacrylate, and Lava. EVOH is a biocompatible polymer that is commonly used to treat arteriovenous malformations, dural arteriovenous fistulas, and aneurysms. Cyanoacrylate is a glue-like substance that polymerizes when it comes into contact with blood. It is used to treat vascular malformations, aneurysms, and bleeding in the gastrointestinal tract. Lava is a liquid embolic agent that solidifies when it comes in contact with a solvent. It is used to treat arteriovenous malformations, aneurysms, and certain brain tumors.
