What is Conservative Management of Patent Ductus Arteriosus Is Feasible in the Peri-Viable Infants at 22–25 Gestational Weeks about?

The purpose of this study was to determine the natural course of hemodynamically significant (HS) patent ductus arteriosus (PDA) with conservative management and whether the presence or prolonged duration of HS PDA affected mortality/morbidities in infants at 22–25 weeks estimated gestational age (EGA). We retrospectively reviewed the medical records of 77 infants born at 22–25 weeks EGA, stratified into 22–23 weeks (n = 21) and 24–25 weeks EGA (n = 56). HS PDA was present in 77%, 76%, and 77%, and open ductus at discharge was 12%, 13%, and 12% in the total and at 22–23 and 24–25 weeks EGA infants, respectively. For backup rescue treatment, 7% and 5% of the infants received oral ibuprofen and device closure, respectively. A mortality rate of 9% was found in the HS PDA (+) infants, significantly lower than the 28% in HS PDA (−) infants. There are no significant differences in morbidities. In multivariate analyses, the presence and/or prolonged duration of HS PDA was not associated with increased mortality or morbidity. Spontaneous closure of HS PDA was achieved through conservative management in the peri-viable infants at 22–25 weeks EGA.
