'''Bile duct hyperplasia''' around portal regions is a non-specific response to a variety of long-standing hepatic insults, but occurs especially in association with diseases that [[Biliary Tract - Obstruction|obstruct bile drainage]].

'''Vascular abnormalities''' are also associated with cirrhosis. Anastomoses occur between the hepatic portal vein and systemic vasculature due to increased portal pressure. Additionally, [[Portosystemic Shunt|vascular shunts]] can result within regenerative nodules, either between central and portal veins, or  between hepatic arteries and central veins.
