Alveolus TB-STS is a new self-expanding, completely polyurethane-covered, metallic stent which has been designed to be successfully used even in the treatment of non-neoplastic airway strictures as it is supposed to be removable. We recently observed the collapse of an Alveolus tracheal stent, causing dyspnea and hemopthysis, in a 63-yr-old female patient with post-intubation tracheal stenosis. Such a complication, which to our knowledge has never been previously reported with metallic stent use, forced us to remove the stent.
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.
