Background: Preeclampsia (PE) is a disorder that causes hypertension and proteinuria after week 20 of pregnancy. Several Uterine Artery (UtAs) Doppler characteristics have been investigated for their ability to predict PE. The purpose of this research is to look into the uterine and umbilical arterial Doppler indices in the early second trimester for the prediction of late preeclampsia or intrauterine growth restriction. Methods: This is a prospective cohort clinical study and was done at Obstetrics and Gynecology department, faculty of medicine Tanta university hospital from January 2020 till April 2021. 150 pregnant women aged from 18 to 30 years old with gestational age from 13 to 16 weeks of pregnancy. Study was done by the same observer by machine MINDRAY DC60 Measurement of fetal biometry (BPD, FL, AC, HC) Gestational age was confirmed with Detection of congenital malformation.    Results: There is a significant difference between the groups regarding uterine and umbilical artery doppler Indices. Uterine RI only yielded significance for predicting IUGR with sensitivity of 62% and specificity of 88%, with Positive predictive value (PPV) 37% and Negative predictive value (NPV) 92%. Umbilical resistance index achieved sensitivity of 56% and specificity of 82%, with PPV 31% and NPV 30% with on statistical significance. Conclusions: Combination of uterine and umbilical artery Doppler study in early pregnancy is one of the best indicator for prediction of preeclampsia and IUGR. Therefore, Doppler study may be used for the prediction of preeclampsia and IUGR to reduce the maternal and perinatal morbidity and mortality.

This study was designed to evaluate the degree of placenta share discordance in relation to the betamethasone-induced return of positive end-diastolic flow in monochorionic twin pregnancies with selective intrauterine growth restriction (sIUGR) and abnormal umbilical artery Doppler. Monochorionic twins with sIUGR was defined as one twin having an estimated fetal weight below the 10th percentile combined with an estimated fetal weight discordance >25%. The umbilical artery Doppler directly prior to (D0) and 24 hours (D1) and 48 hours (D2) after the first dose of betamethasone administration was recorded. The estimated individual placental weight in monochorionic twins was obtained by cutting the placenta along the vascular equator into two territories; the placenta share discordance was calculated as [(estimated individual placental weight of appropriated for gestational age twin- estimated individual placental weight of growth restricted twin)/estimated individual placental weight of appropriated for gestational age twin] × 100%. Six (23.1%) of the 26 included cases achieved betamethasone-induced return of positive umbilical artery end-diastolic flow. The difference of placenta share discordance and birth weight discordance were not significantly different between twins with and without betamethasone-induced return of positive umbilical artery end-diastolic flow. Thus, according to our study results, it was proposed that although the placenta share discordance correlated with the abnormal umbilical artery Doppler in the IUGR fetus in monochorionic twin, the betamethasone-induced return of positive umbilical artery end-diastolic flow, however, did not reveal the similar relationship with the severity of placenta share discordance.

Objective Both fetuses may be affected negatively as a result of the non-equal share of the placenta and vascular anastomoses in monochorionic pregnancies with selective intrauterine growth restriction (sIUGR). In our study, we aimed to investigate the perinatal outcomes of both larger and smaller fetuses in monochorionic pregnancies with and without sIUGR (non-sIUGR) separately. Methods A total of 196 monochorionic twin pregnancies were evaluated retrospectively between January 2013 and January 2019. The cases were grouped as sIUGR and non-sIUGR pregnancies. The pregnancies with sIUGR were also separated into sub-groups as the cases with normal umbilical flow pattern and the cases with abnormal umbilical flow pattern. The perinatal outcomes were investigated separately between the groups for larger and smaller fetuses. Results Of 153 monochorionic pregnancies included in the study, 17.6% (n=27) were sIUGR cases and 82.4% (n=126) were non-sIUGR cases. While the umbilical artery flow pattern was normal in 59.3% (n=16) of the pregnancies which developed sIUGR, 40.7% (n=11) of them had abnormal umbilical artery flow pattern. The preeclampsia rate was found significantly higher in sIUGR pregnancies than non-sIUGR pregnancies (25.9% vs. 11.1%, p=0.042). The need for intensive care for both larger and smaller newborns was significantly higher in sIUGR pregnancies compared to non-sIUGR pregnancies (p<0.001). Three (11.1%) of newborns in sIUGR pregnancies passed away during neonatal period. All of the newborns that passed away were the smaller newborns from sIUGR pregnancies with abnormal umbilical artery flow pattern. Conclusion The pregnancies with selective intrauterine growth restriction (sIUGR) are more associated with high risks in terms of perinatal outcomes compared to the pregnancies with non-sIUGR. In pregnancies developing sIUGR, the risk increases for larger fetus as well as smaller fetus. More prospective studies are needed to investigate whether this increased risk in the pregnancies with sIUGR is associated with prematurity which is more common or is a result of sIUGR.
