The selection of an embolic agent should be based on the clinical indication for the procedure, the desire to produce temporary or permanent occlusion, the level of occlusion (proximal or distal), flow dynamics/collateral circulation, the risk of complications such as necrosis or nontarget embolization, and cost. Microparticles can be made of several types of materials, including polyvinyl alcohol (PVA foam embolization particles, Cook Medical, Bloomington, IN), acrylamido polyvinyl alcohol (Bead Block, Biocompatibles UK Ltd, Surrey, UK), hydrogel core with Polyzene-F coating (Embozene microspheres, CeloNova Biosciences, Inc., San Antonio, TX), trisacryl gelatin microspheres (Embosphere microspheres, Merit Medical Systems, Inc., South Jordan, UT), and a combination of vinyl acetate and methyl acrylate with sodium acrylate alcohol copolymer (HepaSphere microspheres, Merit Medical Systems, Inc.).
