Cholangiocarcinoma, whether arising from the intrahepatic or extrahepatic biliary system, is a rare but devastating malignancy. Prognosis is poor, with 5-year overall survival <5% including patients undergoing surgery. Resection is the only curative treatment; however, only ∼30% of patients present at a resectable stage, and intrahepatic recurrence is common even after complete resection. This article discusses the current role of transarterial therapies in the treatment of intrahepatic cholangiocarcinoma.
