Hepatic vein obstruction (Budd-Chiari)

Definition

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

Alternative Names

Budd-Chiari syndrome; Hepatic veno-occlusive disease

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 blood clotting
Oral contraceptives
Pregnancy

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:

CT scan or MRI of the abdomen
Doppler ultrasound of the liver veins
Liver biopsy
Liver function tests
Ultrasound of the liver

Treatment

Treatment varies, depending on the cause of the blockage.

Your health care provider may recommend the following medicines:

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

Surgery may be recommended. This may involve:

Angioplasty and stent placement
Transjugular intrahepatic portosystemic shunt (TIPS)
Venous shunt surgery
Liver transplant

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
