Abstract
OBJECTIVE
To improve the treatment outcomes in patients with primary and metastatic liver tumors localized in segments VII-VIII involving the right hepatic vein and its branches.
MATERIAL AND METHODS
There were 16 surgical interventions including resection of liver segment VII and/or VIII with resection of the right hepatic vein and its branches without reconstruction. All procedures were carried out at the Department of Liver and Pancreatic Tumors of the Blokhin National Medical Cancer Research Center for the period 2016-2020. The cause of surgery was colorectal cancer liver metastases in 8 patients, hepatocellular carcinoma in 2 cases, angiomyolipoma in 1 case and metastases of uterine cancer in 1 patient. Minor liver resection was additionally performed in 5 cases.
RESULTS
Median surgery time was 150 (80-220) min, intraoperative blood loss - 400 (100-2000) ml. Afferent blood flow was blocked in 4 patients for 14 (12-25) min. None patient had intraoperative signs of impaired venous outflow. Biliary fistula in postoperative period occurred in 1 patient. No complications were noted in other cases. Median postoperative hospital-stay was 13 (9-19) days. There were no specific complications in long-term postoperative period that could be associated with venous outflow blockade through the right hepatic vein.
CONCLUSION
Existing vessels and intrahepatic collaterals de novo can provide adequate venous outflow into the middle hepatic vein and short hepatic veins during resection of liver segments VII and/or VIII with resection of the right hepatic vein and its branches without reconstruction and the absence of inferior right hepatic vein.
