METHOD OF VASCULAR LIVER ISOLATION DURING RESECTION, USING TEMPORARY ENDOVASCULAR OCCLUSION Russian patent published in 2020 - IPC A61B17/00 A61M25/10 

FIELD: medicine.

SUBSTANCE: invention relates to medicine, namely to abdominal surgery. First stage involves the temporary endometrial occlusion of the efferent blood flow in the median hepatic vein by the endovascular cylinder. That is followed by crossing the vascular-secretory pedicle of the hepatic lobe of the liver in the portal gates, resulting in demarcation of the removed lobe of the liver. Liver is separated in the portal and caval gates from the vena cava. Braid is applied and the liver is suspended above the inferior vena cava. Short hepatic veins are sequentially bandaged from the removed lobe. Lobar hepatic vein is ligated and transected on the affected side. Vascular anatomical border is used to dissect a hepatic parenchyma by bandaging the tubular structures in a resection line, completing haemostasis. Blood flow is recovered through a median vein of the liver by removing the balloon.

EFFECT: method enables eliminating retrograde blood loss from the median vein of the removed lobe in anatomical resections, to preserve a median vein, to separately treat medial vein inflows on the side of removal, without damaging the vein shaft, exclude the possibility of air and tumor embolism with preserved contralateral blood flow, provide complete vascular isolation of the removed liver lobe, avoiding haemodynamic disorders without reducing central venous pressure, reducing intraoperative injuries by avoiding hepatic ischemia, and reducing overall blood loss.
