Bile duct strictures associated with hepatic arterial infusion chemotherapy

Abstract
We report 6 cases of bile duct strictures in patients receiving intraarterial floxuridine chemotherapy for metastatic colon carcinoma. The computed tomographic and cholangiographic features of these cases mimic those seen with primary sclerosing cholangitis. The postulated mechanism for development of biliary strictures is direct toxicity and/or occlusion of the peribiliary vascular plexus with resultant biliary fibrosis.
