Classes of embolents

Embolent	Mechanism of action
Coils	Reduce blood flow inducing thrombosis Cause vessel wall damage
Amplatzer Vascular Plug	Plug the vessel wall, damaging the wall and promoting thrombogenesis
Particulate embolization agents	Reduce blood flow, initiating thrombosis and promoting angionecrosis of the vessel wall
Gelatin foam/powder	Forms a cast of the vessel forming a surface for thrombogenesis and occlusion
Tissue adhesives (glue)	Forms a cast of the vessel and incites an inflammatory response
Sclerosing agents	Directly toxic to the tissues, inducing tissue necrosis
