Pulmonary Artery Doppler And Neonatal Outcome In Hypertensive Disorders Of Pregnancy

"A full obstetrics ultrasound scan will be performed within 24 hours before delivery to document fetal biometry, estimated fetal weight and correlate it to fetal growth charts to exclude IUGR, amniotic fluid index and umbilical artery Doppler studies.~Fetal echocardiography will be done.Pulmonary artery Doppler flow waveforms, including pulsatility index, resistance index, systolic-to-diastolic ratio, peak systolic velocity, and acceleration time to ejection time (At/Et) ratio will be measured in the main pulmonary artery."
