Introduction

Background

Budd-Chiari syndrome is an uncommon condition induced by thrombotic or nonthrombotic obstruction to hepatic venous outflow. Budd described it in 1845, and Chiari added the first pathologic description of a liver with "obliterating endophlebitis of the hepatic veins" in 1899. Hepatomegaly, ascites, and abdominal pain characterize Budd-Chiari syndrome.

The syndrome most often occurs in patients with underlying thrombotic diathesis, including myeloproliferative disorders, such as polycythemia vera and paroxysmal nocturnal hemoglobinuria, pregnancy, tumors, chronic inflammatory diseases, clotting disorders, and infections.

Pathophysiology

Obstruction of intrahepatic veins leads to congestive hepatopathy. This results from obstruction of large- or small-caliber veins, which leads to hepatic congestion as blood flows into, but not out of, the liver. Hepatocellular injury results from microvascular ischemia due to congestion. Portal hypertension and liver insufficiency result.1,2

Frequency

United States

Budd-Chiari syndrome is rare, but the exact frequency is unknown.

International

Internationally, Budd-Chiari syndrome is also rare, but the exact frequency is unknown. Membranous webs are a common cause of Budd-Chiari syndrome in Asian countries.

Mortality/Morbidity

Budd-Chiari syndrome is a potentially fatal disorder, if untreated.

Race

The syndrome occurs in persons of all races.

Sex

The syndrome is equally present in both sexes. Emergent presentation is more common in women than in men.

Age

Age at presentation is usually the third or fourth decade of life, although the condition may also occur in children or elderly persons.

Clinical

History

The classic triad of abdominal pain, ascites, and hepatomegaly is observed in the vast majority of patients but is nonspecific. A high index of suspicion is needed to make the diagnosis.

Four main clinical variants have been described: acute liver disease, subacute liver disease, fulminant liver disease, and liver failure. The most common presentation is subacute liver disease complicated by portal hypertension and varying degrees of liver decompensation.1,2,3

  • Acute and subacute form: These forms are characterized by rapid development of abdominal pain, ascites, hepatomegaly, jaundice, and renal failure.
  • Chronic form: This form of presentation is the most common. Patients present with progressive ascites. Jaundice is absent, and approximately 50% of patients also have renal impairment.
  • Fulminant form: This form of presentation is uncommon. Fulminant or subfulminant hepatic failure is present along with ascites, tender hepatomegaly, jaundice, and renal failure.

Physical

Physical examination may reveal the following findings:

  • Icterus
  • Ascites
  • Hepatomegaly
  • Splenomegaly
  • Ankle edema
  • Stasis ulcerations
  • Prominence of collateral veins

Causes

Most patients have an underlying thrombotic diathesis. In approximately one third of patients, an underlying cause is not evident.

The causes of Budd-Chiari syndrome are as follows:

  • Hematological disorders
    • Polycythemia rubra vera
    • Paroxysmal nocturnal hemoglobinuria
    • Unspecified myeloproliferative disorder
    • Antiphospholipid antibody syndrome
    • Essential thrombocytosis
  • Inherited thrombotic diathesis
    • Protein C deficiency
    • Protein S deficiency
    • Antithrombin III deficiency
    • Factor V Leiden deficiency
  • Pregnancy and postpartum4
  • Membranous webs
  • Oral contraceptives
  • Chronic infections
  • Chronic inflammatory diseases
  • Tumors
    • Hepatocellular carcinoma5
    • Renal cell carcinoma
    • Leiomyosarcoma
    • Adrenal carcinoma
    • Wilms tumor
    • Right atrial myxoma
  • Miscellaneous
    • Alpha1-antitrypsin deficiency
    • Trauma
    • Dacarbazine
    • Urethane
  • Idiopathic
