A method for preparation of a composition for endovascular embolization of brain arteriovenous malformations comprises the use of a substance composition, namely polymer, X-ray contrast substance and dimethylsulfoxide. The preparation of a composition ois carried out at heating of polyethylenvinyl alcohol in dimethylsulfoxide at temperature of 90 °C within 3-7 hours with subsequent dissolution of N,N-bis(2,3-dihydroxypropyl)-5 [N-(2,3- dihydroxypropyl)acetamido]-2,4,6-triiodineisophtalimide in said solution at temperature of 70-80 ° C within 10-25 minutes. |
