The present invention relates to a vascular embolic material for use in the treatment of an angiotropy of various tumors and a vascular malformation. Specifically, the present invention relates to a vascular embolic material having the specific morphological, physicochemical and radiological characteristics and multifunction in the form of a bead or a sponge comprising a mixture of a hydrophilic polymer material and a metal material. The specific physicochemical and radiological characteristics of the vascular embolic material according to the present invention facilitate its clinical use and aid in the diagnosis before and after the embolization. Further, a local radiation treatment and anticancer treatment is possible and thus the therapeutic effect on said disorders can be enhanced.
A vascular embolic material having multifunction in the form of a bead comprising a mixture of a polyvinyl alcohol and a metal material, wherein the metal material is isotoped by a neutron radiation and is selected from the group consisting of Pt and a mixture of Pt and TiO2, and the mixing ratio of the polyvinyl alcohol hydrophilic polymer material and the metal material is 4-10:1.
