A method for forming and the morphological characteristics of artificial liver cysts

: Application of ultrasound surgical aspirator promotes rapid formation of major cavities with dry inner surface in the depth of hepatic parenchyma. Filling of the latter with sutured copolymer of monovinyl ether of ethyleneglycol in the ratio of one filler volume to three cavity volumes results in the formation of cysts with the given stable dimensions. Good aspiration of necrotic tissues promotes rapid formation of thin-walled cysts. The given hepatic cyst model may be used in the development of new surgical and puncture methods of treatment, as well as testing of new drugs.
