Abstract:
A method for embolizing a blood vessel by injecting into said blood vessel a sufficient amount of a composition consisting essentially of:(a) from about 2.5 to about 8.0 weight percent of a polymer selected from the group consisting of polyvinylacetate wherein said polymer has a molecular weight of at least about 50,000; (b) from about 10 to about 40 weight percent of a contrast agent; (c) from about 52 to about 87.5 weight percent of a biocompatible solvent wherein the weight percent of the polymer, contrast agent and biocompatible solvent is based on the total weight of the complete composition whereupon, after injection, a precipitate is formed which embolizes the blood vessel wherein the formed precipitate comprises the polymer.
