Formation, position, course and areas of drainage by hepatic veins were studied in 153 adult autopsy specimens. There were three major hepatic veins; left, middle and right. The middle hepatic vein (MHV) joined the left hepatic vein (LHV) in 88.2% specimens before the latter opened into inferior vena cava (IVC). Each major hepatic vein was joined by a superior vein. An intersegmental vein was present in the septum between the medial and lateral segments; it either joined the LHV or MHV. Formation and course of posterior hepatic veins (small veins) have been described and a nomenclature has been suggested. The right suprarenal vein either opened directly into IVC or joined the superior or inferior posterior hepatic veins.

A rare, asymptomatic case of an extrahepatic portocaval shunt between the posterior aspect of the portal vein and the inferior vena cava.
Surg Radiol Anat

Department of Radiology, International University of Health and Welfare Narita Hospital, 852 Hatakeda, Narita, 286-8520, Chiba, Japan.
Purpose: We present the case of a rare extrahepatic portocaval shunt that resulted in communication of the portal vein and the inferior vena cava (IVC) at the level between two right renal veins that was incidentally diagnosed with contrast-enhanced computed tomography (CECT) in an asymptomatic patient.
Methods: A woman in her sixties with abdominal pain and diarrhea of unclear origin underwent exploratory abdominal CECT.
Results: The CECT incidentally revealed an extrahepatic portocaval shunt, whereby a vessel arising from the portal vein superior to the confluence of the superior mesenteric and splenic veins drained into the posterior aspect of the IVC between two right renal veins.
Electroencephalographic Features of Presumed Hepatic Encephalopathy in a Pediatric Dog with a Portosystemic Shunt-A Case Report.

Hepatic encephalopathy (HE) in dogs is a metabolic disorder of the central nervous system that occurs secondarily to liver dysfunctions, whether due to acquired or congenital causes. A portosystemic shunt is the presence of abnormal communications between the hepatic vessels (portal and suprahepatic veins). As a result of this, the blood brought from the digestive tract through the portal vein bypasses the liver, and the unmetabolized components of the portal bloodstream enter directly into systemic circulation, causing clinical symptoms of metabolic encephalopathy (HE).

Department of Urology, Tufts University Medical Center, 800 Washington St., Boston, MA 02111, USA.
Background: Renal cell carcinoma tends to invade venous structures, frequently extending beyond the inferior vena cava and into the heart itself, such as into the right atrium or right ventricle. Resection of tumor burden, particularly tumor thrombus, often requires cardiopulmonary bypass (CPB) and deep hypothermic circulatory arrest (DHCA), which is not feasible for all patients.
Methods: Described in this study is a novel, minimally invasive endovascular approach involving endovascular thrombectomy as a viable approach in these select patients.
Predictive model of intrahepatic collateral vessels among hepatic veins in patients with liver tumors involving the caval confluence.

Background: Communicating vessels among hepatic veins in patients with tumors invading/compressing hepatic veins at their caval confluence facilitate new surgical solutions. Although their recognition by intraoperative ultrasound has been described, the possibility of preoperative detection still remains uncertain. We aimed to develop a model to predict their presence before surgery.

The unique architecture of the liver consists of hepatic lobules, dividing the hepatic features of metabolism into 2 distinct zones, namely the pericentral and periportal zones, the spatial characteristics of which are broadly defined as metabolic zonation. R-spondin3 (Rspo3), a bioactive protein promoting the Wnt signaling pathway, regulates metabolic features especially around hepatic central veins. However, the functional impact of hepatic metabolic zonation, regulated by the Rspo3/Wnt signaling pathway, on whole-body metabolism homeostasis remains poorly understood.
