Treatment of Budd-Chiari Syndrome with Long-Segment Thrombotic Occlusion of the Hepatic Veins
This protocol addresses Budd-Chiari syndrome presenting with long-segment thrombotic occlusion of the hepatic veins accompanied by signs of liver failure, ascites, or varices — a clinically severe presentation that typically requires prompt, structured management.
Long-segment hepatic vein occlusion is more severe than short-segment disease and is the predominant pattern in Western populations. In symptomatic patients — those with liver failure, ascites, or varices — early escalation of management is generally indicated without deferring to an observation period under medical treatment alone.
Anticoagulation is started immediately upon diagnosis, with anticoagulant selection influenced by a heparin sensitivity observed in a significant proportion of these patients. The full structured regimen — including sequencing, additional interventions, and the complete decision algorithm — is available via the protocol below.
Management targets resolution of ascites, achievement of a negative sodium and water balance, adequate coagulation factor recovery, and a decline in conjugated bilirubin if initially elevated.

The long-segment thrombotic occlusion of hepatic veins, common in Western countries, is more severe and may require a portocaval shunting procedure to relieve hepatic and splanchnic congestion.
In symptomatic patients (liver failure, ascites, varices), early TIPSs may be indicated without waiting on their response to medical treatment.
Anticoagulation is mandatory as soon as a diagnosis of BCS is made.
Heparin should be avoided since about 30% of patients have heparin antibodies at the onset of the disease. This is why low-molecular-weight heparin is preferred.
