A study was carried out to investigate the biological fate of spongy polyurethane aortic prostheses after a period of implantation of 7 to 10 years in dogs. The present findings indicate that this material is in a sense accepted by the organism (not only tolerated) because almost complete reorganization of the arterial elastic structures inside the prostheses and the formation of arterial branches from the prostheses were observed.
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.
