Hepatic vein obstruction (Budd-Chiari)

Hepatic vein obstruction is a blockage of the hepatic vein, which carries blood away from the liver.

Causes

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 a tumor or growth pressing on the vessel, or by a clot in the vessel (hepatic vein thrombosis).

Most often, it is caused by conditions that make blood clots more likely to form, including:

  • Abnormal growth of cells in the bone marrow (myeloproliferative disorders)
  • Cancers
  • Chronic inflammatory or autoimmune diseases
  • Infections
  • Inherited (hereditary) or acquired problems with excessive blood clotting
  • Oral contraceptives
  • Pregnancy
  • Antiphospholipid antibody syndrome
  • Paroxysmal nocturnal hematuria

Hepatic vein blockage is the most common cause of Budd-Chiari syndrome.

Symptoms

Symptoms include:

  • Abdominal swelling or stretching due to fluid in the abdomen
  • Pain in the right upper abdomen
  • Vomiting blood
  • Yellowing of the skin (jaundice)

Exams and Tests

One of the signs is swelling of the abdomen from fluid buildup (ascites). The liver is often swollen and tender.

Tests include:

Treatment

The treatment varies, depending on the cause of the blockage.

Your health care provider may recommend the following medicines:

  • Blood thinners (anticoagulants)
  • Clot-busting medicines (thrombolytic treatment)
  • Medicines to treat the liver disease, including ascites

Surgery may be recommended. This may involve:

Possible Complications

Hepatic vein obstruction can get worse and lead to cirrhosis and liver failure. This can be life threatening.

When to Contact a Medical Professional

Contact your provider if:

  • You have symptoms of hepatic vein obstruction
  • You are being treated for this condition and you develop new symptoms

Alternative Names
