Final answer:
Budd-Chiari syndrome is a medical condition characterized by the obstruction of hepatic veins, leading to liver-related symptoms and requiring prompt treatment.
Step-by-step explanation:
The medical condition characterized by the thrombosis of hepatic veins is referred to as Budd-Chiari syndrome. This serious condition occurs when there is an obstruction of the hepatic vein, which leads to a variety of symptoms including abdominal pain, ascites, and liver enlargement. Unlike conditions that affect the biliary tree or result in jaundice, such as Gilbert's syndrome or biliary tree obstruction, Budd-Chiari syndrome specifically involves the vascular system of the liver and can have serious consequences if not treated promptly.
