Three cases of pseudoaneurysm of subclavian artery in long-term follow-up after staged repair of tetralogy of Fallot are described. The angiographical study revealed that aneurysms were located in the systemic end area of previously ligated modified Blalock-Taussing shunt. Aneurysmectomy with resection of a shunt and segment of subclavian artery was performed. We believe division of a prosthetic shunt should be routinely performed during complete repair of tetralogy to prevent morbidity in the long-term follow-up period.
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.
