Budd-Chiari syndrome is a condition in which the veins that carry blood from the liver are blocked, causing liver congestions. It typically presents with a classic triad of symptoms, that include abdominal pain, ascites, and liver enlargement. There are two types of Budd-Chiari syndrome: primary and secondary. Primary Budd-Chiari syndrome is due to the obstruction to the hepatic veins caused by a venous process like thrombosis or phlebitis. In secondary Budd-Chiari syndrome the obstruction comes from the compression or the invasion of the hepatic vein by a non-venous process, usually by a tumor nearby.
