Transcatheter vs Surgical PDA Closure in Preterm Infants Shows Similar Respiratory Outcomes: JAMA
Researchers have found in a cohort study of extremely preterm infants that respiratory outcomes were comparable between those undergoing transcatheter closure and surgical ligation for patent ductus arteriosus (PDA), despite a longer PDA exposure in the transcatheter group. Further research is needed to determine the optimal timing for transcatheter intervention.
Transcatheter closure of the patent ductus arteriosus (PDA) has increasingly been adopted in extremely preterm infants as a method to definitively close the PDA while avoiding the inherent risks of surgical ligation. Differences in respiratory outcomes after transcatheter closure compared with surgical ligation have not been substantiated, particularly in the context of timing of the intervention.
A study was done to characterize respiratory outcomes in extremely preterm infants with PDA treated with transcatheter device closure compared with surgical ligation. This retrospective cohort study assessed data from preterm infants born at less than 29 weeks’ gestation or with birth weight less than 1000 g who underwent definitive PDA closure in neonatal intensive care units participating in the Neonatal Research Network’s Generic Database between January 1, 2016, and December 31, 2020. Data were analyzed from October 2021 to February 2024.
