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 lump (tumor) pressing on the vessel, or by a clot (thrombus) in the vessel.
Most often, it is caused by conditions that make blood clots more likely to form, including:
- Abnormal spread of cells from the bone marrow (myeloproliferative disorders)
- Cancers
- Chronic inflammatory or autoimmune diseases
- Infections
- Inherited (hereditary) or acquired problems with blood clotting
- Oral contraceptives and pregnancy
Symptoms
- Pain on the right side of the abdomen
- Vomiting blood
- Yellowing of the skin (jaundice)
Exams and Tests
One of the signs is swelling of the abdomen from fluid build-up (ascites)
Tests include:
Treatment
Treatment varies, depending on the cause of the blockage.
Medical treatments:
- Blood-thinning (anticoagulation) medications
- Clot-busting drugs (thrombolytic treatment)
- Treatment for the liver disease, including ascites
Surgical treatments:
- Angioplasty and stent placement
- Transjugular intrahepatic portosystemic shunt (TIPS)
- Other surgeries
Possible Complications
Hepatic vein obstruction can get worse and lead to liver failure, which can be life-threatening.
