Budd-Chiari syndrome is a rare disorder characterized by narrowing and obstruction of the veins of the liver.[1] This narrowing or obstruction slows or prevents blood from flowing out of the liver and back to the heart which can lead to liver damage.[2] While some people experience no symptoms, many experience fatigue, abdominal pain, nausea, and jaundice. Other associated findings include an accumulation of fluid in the abdomen (ascites), an enlarged spleen and/or liver, and severe bleeding in the esophagus.[1][3] The severity of the disorder varies from case to case, depending on the site and number of affected veins.[1] Drugs may be used to dissolve or decrease the size of the obstruction (if it is a clot). In some cases surgery is performed.[3] In most cases, the cause of Budd-Chiari syndrome is unknown.[1]
