METHOD FOR RADICAL TREATMENT OF PATIENTS WITH METASTATIC LIVER TUMORS Russian patent published in 2023 - IPC A61M5/00 A61M25/01 A61B6/03 A61B8/00 A61K31/7115 A61K31/282 A61K31/513 A61P35/00 A61P1/16 

FIELD: medicine; oncology; endovascular surgery.

SUBSTANCE: at the first stage, the patient undergoes single-photon emission computed tomography combined with computed tomography of the liver to calculate the functional reserve of the liver. Then, under intravenous sedation and local anaesthesia with 20 ml of novocaine 0.5% under ultrasound control, a puncture of the right branch of the portal vein with a Hiba needle is performed with its further embolization with microspheres and adhesive agents. Next, 2 courses of hepatic artery chemoembolization (HAC) are carried out, followed by single-photon emission computed tomography combined with computed tomography of the liver with calculation of the functional reserve of the liver. The target threshold value of the functional reserve of the remaining liver segments is more than 2.7%/min/m², which makes it possible to perform radical treatment and, accordingly, increase the percentage of curable patients.

EFFECT: this method allows to increase the number of curable patients due to the ability to perform radical treatment and transfer the patient from an unresectable to a resectable state.
