Trends in patent ductus arteriosus ligation in neonates and changes in outcomes: A 10-year multicenter experience.

Over the 10 years examined, neonates underwent PDA ligation at an older age in the second 5-year time period; this change was not associated with a change in the incidence of major morbidities. Ligation age >28 days was associated with an increase incidence of moderate-severe BPD. The overall incidence of documented VCP post-PDA ligation was relatively low but was seen in over 1/3 who were evaluated by laryngoscopy.
