Background: The objective of the present study was to find out association between aortic isthmus Doppler changes and perinatal outcome in growth restricted fetuses with placental insufficiency.Methods: It is a prospective case control study, cases were 43 pregnant women with fetal growth restriction (FGR) with abnormal umbilical artery (UA) Doppler while 43 pregnant women with FGR but normal UA doppler, matched with period of gestation were taken as control. The direction of blood flow in aortic isthmus studied which may be antegrade, absent or retrograde and correlation between qualitative parameters of umbilical artery, aortic isthmus and ductus venosus were studied. Quantitative parameters, PI and RI were also calculated. Patients were managed as per hospital protocols. Perinatal outcome and any adverse event e.g. stillbirth, neonatal death, respiratory distress syndrome, intensive care unit stay >14 days etc. was noted.Results: The number of intrauterine death (IUD) and still birth was increased in women with absent and retrograde flow in aortic isthmus, 66.7% and 71.4% respectively (p value <0.001). Retrograde blood flow in the aortic isthmus is consistently associated with absent or reverse end diastolic velocity in umbilical artery and ductus venosus.Conclusions: Doppler of aortic isthmus is an additional parameter to assess severity of FGR. It plays an important role in termination of preterm FGR fetuses.

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.
