In an infant with tetralogy of Fallot submitted to angiographic study, a double aortic lumen was found. Although no particular complaints were related to the additional abnormality, we report this case to emphasize the possibility of occurrence of persistent embryonic fifth aortic arch.

The authors present the case of an infant with non-syndromic complete atrioventricular septal defect, whose post-operative period was surprisingly complicated by progressive pulmonary hypertension. Despite intensive care, the infant ultimately died. The diagnosis of unilateral primary pulmonary lymphangiectasia was only possible post mortem.
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.
