Causes
- Primary (75%): thrombosis of the hepatic vein
- Secondary (25%): compression of the hepatic vein by an outside structure (e.g. a tumor)
Often, the patient is known to have a tendency towards thrombosis, although Budd-Chiari syndrome can also be the first symptom of such a tendency. Genetic causes
- Protein C deficiency
- Protein S deficiency
- Factor V Leiden mutation
Other causes
A related condition is veno-occlusive disease, which occurs in recipients of bone marrow transplants as a complication of their medication. Although its mechanism is similar, it is not considered a form of Budd-Chiari syndrome.
