Portal vein thrombosis (PVT) is a vascular disease of the liver that occurs when a blood clot occurs in the hepatic portal vein, which can lead to increased pressure in the portal vein system and reduced blood supply to the liver. The mortality rate is approximately 1 in 10.
Inherited disorders of hypercoagulability may lead to thrombosis of the hepatic vein and Budd–Chiari syndrome. Factor V Leiden is responsible for 8% of cases. [ 2 ] Other less common inherited disorders leading to the condition include factor II mutation (3%), protein C deficiency (5%), protein S deficiency (4%), and antithrombin III ...
Preoperative PVE is a very well tolerated procedure with extremely low mortality rates (0.1 percent) and technical failure rates (0.4 percent). [3] Complication rates from the procedure are low as well (2–3 percent) and include portal vein thrombosis, liver infarction, necrosis, infection, pneumothorax, and other risks as listed above. [3]
The hepatic vein subsequently drains into the inferior vena cava. The hepatic artery provides 30 to 40% of the oxygen to the liver, while only accounting for 25% of the total liver blood flow. The rest comes from the partially deoxygenated blood from the portal vein. The liver consumes about 20% of the total body oxygen when at rest. That is ...
The portal vein and its branches supply most of the blood and nutrients from the intestine to the liver. [6] Cirrhosis (a form of chronic liver failure) is the most common cause of portal hypertension; other, less frequent causes are therefore grouped as non-cirrhotic portal hypertension.

The portal vein or hepatic portal vein (HPV) is a blood vessel that carries blood from the gastrointestinal tract, gallbladder, pancreas and spleen to the liver.This blood contains nutrients and toxins extracted from digested contents.
Hepatic veno-occlusive disease (VOD) or veno-occlusive disease with immunodeficiency is a potentially life-threatening condition in which some of the small veins in the liver are obstructed.
