Poly(HEMA)--based embolic material in endovascular surgery of liver.

Physico-chemical and medico-biological methods, including hematology and cytology, were used in an evaluation of properties of poly(2-hydroxyethyl methacrylate) (poly(HEMA))-based embolic material indicated in the occlusion of branches of hepatic artery of patients with focal alterations of the liver. The elastographic method helped in predicting mechanical properties of the hydrogel material. Poly(HEMA) was mechanically stable for endovascular applications, exhibited no significant loss in elasticity and possessed consistency resembling the soft tissue of the organism.
