Intrauterine ductus arteriosus constriction: analysis of a historic cohort of 20 cases.
To describe the relative incidence, presentation, and evolvement of fetuses with early ductus constriction. ⋯ The high incidence of idiopathic constriction of the ductus arteriosus suggests that its diagnosis is underestimated and that many cases of persistence of fetal circulation in newborns may be related to constriction of the ductus arteriosus not diagnosed during intrauterine life. Group B had a lower severity but a risk of an unfavorable evolvement, suggesting a distinct alteration.
