What is the liver vein?

liver vein is some of the veins that carry oxygen depleted blood from the liver and to the lower vena cava. The term veins concerns the blood vessel that transports blood back to the heart, unlike the artery that carries blood from the heart. The term liver concerns the liver.

The liver veins group meets the lower vena cava on the back or back, side of the liver. Vena Cava is the main blood vessel, which in turn transports blood to the right heart of the heart, where blood can begin the ooxygenated process. This is because the liver acts as a cleaning station on the blood route back to the heart to re -ooxenic. In the liver there is a phagocytic or killing of cells that kills bacteria that could enter the blood, especially through the intestines and get rid of dead or damaged blood cells. The liver can also store and release a large amount of blood to control the volume of blood circulated through the body at the moment. Because it receives so much blood, the liver is a very vascular organ or organ in a high holding of blood vessels.

The liver receives deoxygenated blood from other organs through liver portal veins and oxygenated blood to feed the liver artery. At the terminal or at the end of the branches of the liver portal veins and the liver arteries, arterial and venous blood consists of sinusoids, which in turn empties into the central veins located in each lobule. Sinusoids are specialized blood vessels with phenestrations or small gaps between cells to increase plasma permeability and damaged cells to leave blood circulation. Each lobule has its own central vein that collects blood from sinusoids and passes it to groups of liver veins.

liver veins are divided into two groups, upper and lower, based on where the veins emerge from the liver. The lower group emerges from the right lobe and the caudate lobe of the liver and may vary in number from man to man. The upper group emerges from the quadrate LaloKu and left lobe on the back of the liver. There are usually three liver veins in the upper group and tend to be larger than the veins of the upper group.

The

Budd-Chahari syndrome occurs when the liver vein drain is blocked by an obstacle in the liver vein, lower cava vena or the right atrium. This is usually due to a clot in the liver vein, especially in the global West, but it can also be caused by congenital or developmental defects or unknown causes. Symptoms vary depending on whether obstruction suddenly occurs, where patients show pain and signs of Liver failure, or whether this occurs gradually, where patients do not have any pain but begin to show signs of liver failure with time. Common symptoms may be enlarged liver, elevated liver enzymes, ascity, abdominal pain, jaundice and in advanced cases cirrhosis. Treatment options include anticoagulants, sodium reduction, diuretics, surgical shorts, angioplasty and liver transplantation in emergency or lastovisku.
