is abdominal pain a symptom of ascites
1 Budd-Chiari syndrome is caused by the blockage of the hepatic veins (those that drain the liver). 2  This causes the triad of ascites, abdominal pain, and hepatosplenomegaly (enlargement of the liver and spleen). 3  Cancer that has metastasized or spread to the liver can also be the source of ascites.
