Laparoscopic Anatomic S7+S8d Resection Preserving Inferior Right Hepatic Vein and S6 with Right Hepatic Vein Transection
0 Views •
2025
We present a laparoscopic technique for anatomic S7+S8d resection with right hepatic vein transection, preserving the inferior right hepatic vein and segment S6. Relying on meticulous anatomical landmarks without intraoperative ultrasound, this approach offers a precise and parenchyma-sparing option for dorsally located right-liver tumors, particularly in settings with limited advanced navigation resources.

Auxiliary liver transplantation provides a temporary support in acute hepatic failure, until regeneration of the failing liver. The heterotopic auxiliary liver transplantation (HALT) with portal vein arterialization (PVA) renders sufficient liver function. We developed an analogous technique in the rat, to examine the influence of the portal vein arterialization on the morphology and function of the graft.

Marginating-hepatic leukocytes exhibit unique characteristics and distinct immunological functions compared to other leukocyte populations. Here we describe a method for selective harvesting of this specific hepatic cell population, through forced perfusion of the liver of rats or mice. Marginating-hepatic leukocytes seem critical in determining susceptibility to hepatic-related diseases and metastases.

An optical system was developed to visualize hepatic microcirculation with FITC-labeled erythrocytes and to measure the partial pressure of oxygen in the microvessels with laser-assisted phosphorimetry. This method can be used to investigate physiological and pathological mechanisms by analyzing microvascular structure, diameter, blood flow velocity, and oxygen tension.
FAQs
Blood from the hepatic artery and portal vein moves through liver sinusoids before entering central veins. These central veins collect the blood after it has passed among hepatocytes, then merge into larger hepatic veins. This stepwise organization connects microscopic processing regions within the liver to the venous pathway leading toward the heart.
The hepatic artery and portal vein deliver blood to the same sinusoidal network, allowing blood carrying different substances to pass through hepatocyte-rich tissue before collection by central veins. Hepatic veins therefore receive the combined outflow of these inputs, linking nutrient processing, substance metabolism, and waste removal with systemic venous return.
When blood cannot leave the liver efficiently through its venous outflow, the normal relationship among sinusoids, central veins, hepatic veins, and the inferior vena cava becomes clinically important. Evaluating this pathway helps researchers and clinicians investigate venous outflow obstruction and distinguish it from problems centered on portal circulation, including portal hypertension.
Hepatic veins serve as recognizable vascular landmarks during abdominal imaging because they show how blood exits the liver toward the inferior vena cava. Their anatomy and apparent flow pattern can help assess the arrangement of hepatic circulation and support evaluation of vascular disease or suspected obstruction affecting venous outflow.
Their position identifies major venous drainage pathways within and around the liver, making hepatic veins important anatomical landmarks during liver surgery. Understanding these vessels helps relate planned surgical areas to the liver’s outflow system and supports attention to vascular structures that connect hepatic tissue with the inferior vena cava.
In transplantation, hepatic veins provide essential anatomical context for reconnecting or evaluating the liver’s venous outflow. More broadly, their relationship with the inferior vena cava and intrahepatic drainage pathways helps guide assessment of vascular disease. Studying these vessels therefore connects normal liver biology with surgical planning and clinical evaluation.
