Hepatic vein obstruction refers to a blockage of the hepatic vein, which carries blood away from the liver.
Causes, incidence, and risk factors
Hepatic vein obstruction prevents blood from flowing out of the liver and back to the heart. This blockage can cause liver damage. Obstruction of this vein can be caused by masses pressing on the vessel (tumor) or by thrombus (clot) formation within the vessel.
Most often, it is caused by conditions which increase the body's propensity to form blood clots. These include:
Myeloproliferative disorders -- abnormal proliferation of cells from the bone marrow
Oral contraceptives and pregnancy
Right-sided abdominal pain and a large liver
Jaundice (yellowing of the skin)
Ascites (swelling of the abdomen due to the development of fluid in the abdomen)
Signs and tests Return to top
Elevated results of liver function tests
Ultrasound of the liver

Treatment varies, depending on the cause of the obstruction, and may include the following:
Medical therapy for symptoms
Complications Return to top
Hepatic vein obstruction can progress to liver failure, which can be fatal.
