FIELD: medicine, surgery, surgical hepatology, intervention radiation diagnostics.
SUBSTANCE: due to ultrasound control one should introduce monopolar electrodes being parallel to the direction of vessels. Moreover, a cathode is being at the distance of 10 mm against vascular wall. Then comes electrochemical lysis (ECL) for 20 min, not more after the contact of echo-positive formation appeared during the lysis with vascular wall at the distance for not less than 1.3 against metastase diameter. The innovation enables to carry out efficient metastatic lysis near large hepatic vessels at no risk of hemorrhagic growth due to US-criteria of tissue lysis sufficiency being near the vessel without any disorders in muscular layers of vascular wall.
EFFECT: higher efficiency of therapy.
