TLDR
The right HV can be isolated and clamped outside the liver in more than 80% of cases, making it possible to carry out right hepatectomy on an exsanguinous liver.Abstract:
The possibility and value of clamping the right hepatic vein (HV) outside the liver during right hepatectomy remain a matter of debate. We carried out an anatomical study on ten fresh cadaveric subjects with no abdominal scarring or hepatic lesions, to determine the biometry of the extraparenchymatous segment of the right HV. One or several accessory right HVs were found in 90% of cases on release of the right edge of the inferior vena cava (IVC). These accessory right HVs had a diameter greater than that of the superior right HV in 10% of cases. In 70% of cases, the extraparenchymatous segment of the vein was free of collateral branches, and in 30% of cases, it was joined by a branch close to its point of exit from the hepatic parenchyma. The length of the vein that can be clamped (length between the point of exit from the hepatic parenchyma and the point of entry of the right HV into the IVC) was 8.6 ± 1.8 mm (6–12). The right HV entered the vena cava, at an acute angle, in 100% of cases. Clamping of the right HV was possible in all cases. Knowledge of these anatomical points makes it possible to isolate an extraparenchymatous segment of the right HV more safely. The right HV can be isolated and clamped outside the liver in more than 80% of cases, making it possible to carry out right hepatectomy on an exsanguinous liver.read more

Clinical application of hepatic venous occlusion for hepatectomy.
TL;DR: Hepatic venous occlusion applied in hepatectomy can prevent bleeding and air embolism, and is safe and effective with stable hemodynamics.

Can the left hepatic vein always be safely selectively clamped during hepatectomy? The contribution of anatomy
TL;DR: Biometric analyses were carried out on extraparenchymatous portions of the LHV, MHV and CT of 20 fresh cadavers and 10 living subjects, to assess the feasibility of selective clamping without liver mobilization.

TL;DR: Although ductoplasty, internal stent or no stenting, seemed to be associated with increased risk of complications, anatomical variants, multiple bile ducts, and duct-to-duct reconstruction did not bear a significant risk.

TL;DR: Hepatic vascular exclusion, which includes clamping of the portal pedicle along with the inferior vena cava below and above the liver, may be a useful procedure for resection of liver tumors close to the hepatic veins or the venaCava that are usually considered unresectable by conventional techniques.

TL;DR: Both techniques of clamping are equally effective and feasible for patients with normal liver and undergoing minor hepatectomies, however, in cirrhotic patients selective clamping induces less ischemic injury and should be recommended.

Vascular occlusion to decrease blood loss during hepatic resection.
TL;DR: The evidence suggests that inflow occlusion techniques are generally well tolerated and should be used with caution in patients with cirrhosis, fibrosis, steatosis, cholestasis, and recent chemotherapy, and for prolonged time intervals.
