Neonatal outcome after conservative-reconstructive surgery for placenta accreta spectrum disorders

To report the neonatal outcome after conservative-reconstructive surgery for placenta accreta spectrum (PAS) disorders.

Inclusion criteria were women undergoing conservative-reconstructive surgery for PAS. The outcomes explored were: 5 min Apgar score, birth weight, and need for ventilatory support (RS1 supplementary oxygen, RS2 nasal positive pressure ventilation, or RS3 mechanical ventilatory assistance). Descriptive statistics (means and standard deviations for quantitative and percentage and interquartile range for quantitative variables) were sued to report the data.

84% of women with PAS type 1 were delivered between 35 and 37 weeks of gestation. There was only one case of small for gestational age (SGA) newborn 81% of the newborns required admission to the NICU and 11% respiratory support of those pregnancies complicated by PAS type 2, 59% were delivered between 35 and 36.6 weeks. Neonatal birth weight was consistent with gestational age at birth for all the included cases, and there was no SGA newborn in this group. 84% of the newborns required admission to the NICU, while 21% respiratory support. All women with PAS type 3 were delivered between 30 and 33 weeks of gestation. Although all newborns were admitted to NICU and 73% required ventilatory support, there was no SGA case. Pregnancies complicated by PAS type 4 completed their pregnancy between weeks 35 and 37. There was no case affected by SGA; although all newborns were admitted to NICU, none required ventilatory support.

Conservative surgery in pregnancies complicated by PAS does not seem to increase the risk of adverse neonatal outcomes. Early gestational age at birth and invasion in the inferior third of the lower uterine segment is associated with an increased incidence of neonatal complications, likely due to the earlier gestational age at delivery for these pregnancies.
