I have not gone through this prognosis, Mind has to think limited in this aspect, as a patient I should not think deeply about this. However, I have browsed and known as 'The prognosis is poor in patients with Budd-Chiari syndrome who remain untreated, with death resulting from progressive liver failure in 3 months to 3 years from the time of the diagnosis. Following portosystemic shunting, however, the 5-year survival rate for patients with the syndrome is 38-87%'.
