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

Irregular tubular low attenuated lesion along left IHDs with subcapsular low attenuated cystic lesion in left lateral section of liver.
