Ischemic bile duct injury refers to ischemic injury of the intrahepatic bile ducts epithelium commonly seen as a complication of hepatic artery thrombosis following liver transplantation or TACE.
The intrahepatic biliary ducts are exclusively supplied by the peribiliary plexus, which branches from the hepatic artery
IMAGING
– Biliary infarct will manifest as wall irregularities and beading dilatation appearances of the intrahepatic bile ducts associated with marked surrounded hypoattenuation. Multiple cavitations/bile lakes are also characteristic in advanced necrosis
