A case is reported in which multiple needles were inserted into the heart by a patient, resulting in the unusual combination of a coronary artery-cameral fistula to the left ventricle, an intramural defect of the left ventricular free wall and a ventricular septal defect. This unique lesion was suspected on the basis of two-dimensional and Doppler echocardiography and contrast computed tomographic imaging. Its presence was confirmed during cardiac catheterization and cineangiography.
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.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
