Living with Budd-Chiari syndrome

A rare liver condition in which the veins carrying blood out of the liver are blocked.

Understanding Budd-Chiari syndrome

Budd-Chiari syndrome is a rare condition in which the veins that carry blood out of the liver are blocked.

Blood backs up in the liver, which can enlarge the liver and spleen. Pressure rises in the portal vein (portal hypertension), which can cause enlarged veins in the esophagus and fluid in the abdomen (ascites). Severity varies with the site and number of veins affected. It most often occurs with something that makes blood clot more easily, such as pregnancy, a tumor, or a clotting disorder. In about one third of cases the cause is unknown.

Signs & symptoms

Symptoms vary from person to person. GARD lists these among the most common:

  • Abdominal pain
  • Fluid in the abdomen (ascites)
  • Enlarged liver and spleen
  • Swollen ankles and feet
  • Enlarged veins in the esophagus (varices)
  • Fever and tiredness

Not everyone has every symptom. GARD's list comes from the Human Phenotype Ontology.

Diagnosis

  1. Talk with your doctor

    Share the symptoms you've noticed, when they started and your family health history. Notes and photos can help.

  2. See a specialist

    Specialists who may be involved include digestive system specialists.

  3. Ask which tests can help

    Your care team will decide which exams and tests can confirm the diagnosis.
