Abstract
Objective: To correlate ultrasonographic markers of fetal lung maturity including pulmonary artery (PA) Doppler indices in the late preterm and early term pregnancies in placenta accreta spectrumpatients with neonatal outcome
Methods:A prospective cross sectional study was undertaken on patients with PAS disorders singleton women undergoing elective or emergency termination of pregnancy at Kasr Alainyhospital under general anaesthesia at or after 34 weeks. A full obstetrics ultrasound scan was performed within 24 hours before delivery to confirm the eligibility criteria and to measure PA Doppler indices.
Main outcome measures:Acceleration time to ejection time (At/Et) ratio of fetal PA Doppler in neonates with good and poor outcome.
Results: The study included 71 women. None of the PA Doppler parameters correlated with the neonatal need for respiratory support or the neonatal need for resuscitation. Regarding the other ultrasound parameters, only the liver to lung echogenicity and the kidney length correlated with the neonatal need for respiratory support. Fetuses that needed respiratory support had a significantly lower gestational age at delivery, lower EFW, lower birth weight and also lower Apgar score than those whose did not need. The need for respiratory support was more in the neonates who were terminated on emergency basis.The depth of placental invasion correlated with maternal morbidity
Conclusions:PA Doppler parameters do not correlate with the need for respiratory support or the neonatal need for resuscitation in patient with PAS disorders. Regarding the other ultrasound parameters, only the liver to lung echogenicity and the kidney length correlate with the neonatal need for respiratory support
