OBJECTIVE: Impact of prenatal diagnosis (PD) of major abnormalities on neonatal outcome is matter of debate. Unfortunately cases with and without PD may sometimes not be comparable. This is generally related to a lower maturity (GA) and weight (BW) secondary to a high rate of preterm cesarean sections (CSs) for clinical convenience. Present study tried to find out if in utero transfer to a Center with co-located surgical facilities reduces these potential risk factors. METHODS: 152 cases with prenatally detectable conditions were studied and divided according to PD; the following data were compared: GA, BW, obstetrical complications, associated malformations, mode and site of delivery, outcome. Cases with PD delivered in our Center (Inborn, IB) or transferred after birth (Outborn, OB) were compared. RESULTS: 61 cases had a PD (IB/OB ratio 34/27); GA and BW were lower respect to no-PD cases and a higher CS rate was found among OB cases, not justified by complicated pregnancies. No differences in outcome were observed. CONCLUSIONS: Elective preterm CS is still largely practiced for fetuses with PD of a major congenital anomaly in Centers without co-located surgical facilities either in the presumption of safer delivery or to facilitate postnatal transfer. This leads to a lower GA and BW and may spoil potential impact of PD on outcome. This may be avoided promoting prenatal transfer to a Center with co-located surgical facilities.
