What are the 3 hepatic veins?
Three large intrahepatic veins drain the liver parenchyma, into the inferior vena cava (IVC), and are named the right hepatic vein, middle hepatic vein and left hepatic vein. The veins are important landmarks, running in between and defining the segments of the liver.
What is the function of hepatic vein?
The job of the hepatic veins is to move this blood out of your liver. It’s hard work. At any given time, your liver holds about a pint of blood, or about 1/8th of your body’s total blood. The inferior vena cava carries deoxygenated blood from your liver and the lower half of your body to the right side of your heart.
What is a patent vein?
A patent umbilical vein is a sonographic sign of portal hypertension. The specificity of the sign is not known. In a review of 12 patients with sonographically demonstrated patency of the umbilical vein, we found two patients in whom no clinical evidence existed to suggest the presence of portal hypertension.
Where is the Suprahepatic located?
A suprahepatic gallbladder may be located either anteriorly or posteriorly over the dome of the right hepatic lobe.
How hepatic vein is formed?
The hepatic portal vein (Figs 4.60, 4.61) is formed by the union of the superior mesenteric and the splenic veins behind the neck of the pancreas. The inferior mesenteric vein may join the splenic vein or the superior mesenteric vein. The portal vein thus drains blood from most of the gastrointestinal tract.

Where do Paraumbilical veins drain?
The paraumbilical veins are small veins around the falciform ligament that drain venous blood from the anterior part of the abdominal wall and diaphragm directly into the liver, and communicate with other anterior abdominal wall veins.
What vein drains blood from the liver?
Blood leaves the liver through the hepatic veins. This blood is a mixture of blood from the hepatic artery and from the portal vein. The hepatic veins carry blood to the inferior vena cava—the largest vein in the body—which then carries blood from the abdomen and lower parts of the body to the right side of the heart.
Where is the subhepatic vein located in the liver?

What are the names of the hepatic veins?
Dr Craig Hacking ◉ ◈ and Dr Omar Bashir et al. The hepatic veins are three large intraparenchymal veins which drain the liver substance into the inferior vena cava (IVC), named the right hepatic vein, middle hepatic vein and left hepatic vein. The veins are important landmarks, running in between and hence defining the segments…
What are the different types of hepatic capsular and subcapsular lesions?
Miscellaneous lesions include focal fatty sparing or infiltration, surface hepatic and portal veins, pseudolipoma of the Glisson capsule, confluent hepatic fibrosis, and portal vein gas.
How does occlusion of the hepatic veins affect the portal vein?
Occlusion of the hepatic veins results in increased sinusoidal pressure and reverses the pressure gradient between the sinusoidal and portal veins. The portal vein then becomes a draining vein.
