Overview
Classification
- Budd-Chiari syndrome may be classified into several subtypes based on:
- Etiology
- Disease duration and severity
- Anatomical location of occlusion
- An obstruction below 300µm in diameter is not considered as BCS by some authors.
- Budd-Chiari syndrome may be classified according to etiology into two subtypes/groups
- Primary:Hepatic venous outflow obstruction is a result of thrombosis.
- Secondary:Hepatic venous outflow obstruction is a result of invasion or compression by a tumor.
- Budd-Chiari syndrome may be classified according to disease duration and severity into four sub types:
- Acute: Rapid development of clinical manifestations within weeks with intractable ascites and hepatic necrosis.
- Subacute:Insidious onset symptoms develop over 3 months.Clinical manifestations of Ascites and hepatic necrosis may be minimal as portal and hepatic venous collaterals help in decompression of sinusoids.
- Chronic: Associated with complications of cirrhosis.
- Fulminant liver failure: Characterized by acute liver injury with elevated transaminases, jaundice, hepatic encephalopathy, and an elevated prothrombin time/international normalized ratio; hepatic encephalopathy develops within eight weeks after the development of jaundice.
- Venous collaterals are not developed in patients with acute liver failure or acute liver disease whereas venous collaterals are seen in patients with subacute and chronic liver disease.
- Budd-Chiari syndrome may be classified according to anatomical location of obstruction into 3 subtypes: Type I - truncal type, Type II - radicular type, Type III - venooclusive type.
