In human anatomy, the hepatic veins are the veins that drain de-oxygenated blood from the liver into the inferior vena cava. There are usually three upper hepatic veins draining from the left, middle, and right parts of the liver. These are larger than the group of lower hepatic veins that can number from six to twenty. All of the hepatic veins drain into the inferior vena cava.^[1]

They are one of two sets of veins connected to the liver, the others are the portal veins.

The large hepatic veins arise from smaller veins found within the liver, and ultimately from numerous central veins of the liver lobules. None of the hepatic veins have valves.

Structure

The hepatic veins are divided into an upper and a lower group. The upper three drain the central veins from the right, middle, and left regions of the liver and are larger than the lower group of veins.^[1]

The lower group of from six to twenty smaller hepatic veins come from the right lobe and the caudate lobe, are in contact with the hepatic tissue, and are valveless. All the veins empty into the inferior vena cava at the back of the liver.^[1]

Clinical significance

Budd–Chiari syndrome is a condition caused by blockage of the hepatic veins. It presents with a "classical triad" of abdominal pain, ascites, and liver enlargement. The formation of a blood clot within the hepatic veins can lead to Budd–Chiari syndrome. It occurs in 1 out of a million individuals. The syndrome can be fulminant, acute, chronic, or asymptomatic.

The hepatic veins may be connected with the portal veins in a TIPS procedure.

BACKGROUND: Compartmental analysis is a standard method to quantify metabolic processes using fluorodeoxyglucose-positron emission tomography (FDG-PET). For liver studies, this analysis is complex due to the hepatocyte capability to dephosphorylate and release glucose and FDG into the blood. Moreove
