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.

Background: Transarterial chemoembolisation (TACE) is standard of care for patients with unresectable hepatocellular carcinoma that is amenable to embolisation; however, median progression-free survival is still approximately 7 months. We aimed to assess whether adding durvalumab, with or without bevacizumab, might improve progression-free survival.
Methods: In this multiregional, randomised, double-blind, placebo-controlled, phase 3 study (EMERALD-1), adults aged 18 years or older with unresectable hepatocellular carcinoma amenable to embolisation, an Eastern Cooperative Oncology Group performance status of 0 or 1 at enrolment, and at least one measurable intrahepatic lesion per modified Response Evaluation Criteria in Solid Tumours (RECIST) were enrolled at 157 medical sites including research centres and general and specialist hospitals in 18 countries.

Pregnant women with congenital heart disease carry a high risk of complications, especially when cardiac function is suboptimal. Increasing evidence suggests that impaired right ventricular (RV) function has a negative effect on placental function, possibly through venous congestion. We report a case series of hepatic and renal venous flow patterns in pregnant women with right ventricular dysfunction after repaired Tetralogy of Fallot (ToF), relative to those observed in normal pregnancy and preeclampsia.

The liver is supplied by a dual blood flow system consisting of the portal vein and hepatic artery. Imaging techniques for diagnosing hepatocellular carcinoma (HCC) have been developed along with blood flow imaging, which visualizes the amount of arterial and portal blood flow. The diagnosis of HCC differentiation is important for early-stage liver cancer screening and determination of treatment strategies.

Background: Non-alcoholic steatohepatitis (NASH), an advanced manifestation of non-alcoholic fatty liver disease (NAFLD), is characterized by hepatocyte injury, inflammation, and fibrosis. Saturated fatty acids (SFAs) have emerged as key contributors to hepatocyte lipotoxicity and disease progression. Toll-like receptor 4 (TLR4) acts as a sentinel for diverse ligands, including lipopolysaccharide (LPS) and endogenous molecules like palmitic acid (PA)-induced ceramide (CER) accumulation, promoting hepatocyte demise.

Carbon dioxide gas emboli is a potentially fatal complication that occurs more frequently during laparoscopic hepatectomy compared to other laparoscopic surgeries. The patient featured in this report had massive gas embolism confirmed by intraoperative transesophageal echocardiography (TEE) that were associated with episodes of severe hypoxemia, hemodynamic instability, and right ventricular failure requiring conversion to open hepatectomy. Abrupt abdominal decompression resulted in massive hemorrhage from a previously undetected defect in the middle hepatic vein.
