title: Asymptomatic arterio-biliary fistula after transarterial chemoembolization of metastatic liver tumors.
abstract: Arterio-biliary fistula is a rare clinical condition resulting from various causes such as iatrogenic injury and ischemic change of the bile duct. Serious clinical symptoms occur due to the shunting of high-pressure blood from the hepatic artery into the bile duct. Here we report a case of arterio-biliary fistula demonstrated by angiographic examinations. The communication appeared after repeat transarterial chemoembolization of metastatic liver tumors. The interesting point of this case was that the patient did not have any obvious clinical symptoms related to the fistula. The mechanisms responsible for this rare manifestation are discussed.
