LIQUID EMBOLIC AGENTS CONTAINING PARTIALLY HYDROLYZED POLYVINYL ACETATE

摘要

This relates to a composition of matter comprising partially hydrolyzed polyvinyl acetate solutions suitable for use as embolic agent precursors. In addition, a procedure for introducing the solutions into the human body to form precipitated embolic occlusion masses is shown. Finally, a procedure for treatment of hepatic tumors using portal vein embolism is described.
