Background: The uterine and umbilical artery Doppler scan is a valuable tool for evaluation of utero-placental blood flow in pregnancy. They help in detecting uteroplacental insufficiency thus predicting preeclampsia and other effects of faulty placentation which increase the risk of adverse effects on both mother and fetus. Aims and Objective: This study aimed to evaluate and compare the uterine artery and umbilical artery Doppler indices in second and third trimester for prediction of preeclampsia in high-risk pregnancies. Materials and Methods: In this prospective observational study done over a years’ time, 50 high-risk pregnant mothers were recruited and the Doppler scans were done at 21-25 weeks and 31-35 weeks. The necessary clinical observations were recorded throughout the antenatal period and the data analysis was done. Results: Majority (56%) were in 20-29 years range with mean age of 24±6.1 years. Out of the 50 women, 21 had abnormal uterine artery Doppler and 12 had umbilical artery abnormality along with uterine derangement. Preeclampsia developed in 3 of them. The hypertensive disorders of pregnancy were diagnosed in 13 women, preeclampsia in 3, eclampsia in 1and other HDPs in 9. The persistence of notch in uterine artery was observed in 7 women, of these 2 developed PIH. Only one patient had uterine artery PI>1.45 at 24 weeks who subsequently developed preeclampsia. Among 4 patients of preeclampsia and eclampsia, 3 had 2nd trimester uterine and 3rd trimester umbilical Doppler abnormalities and only 1 had normal doppler indices. In 2nd trimester the sensitivity, specificity and PPV are higher for uterine artery PI as compared to umbilical artery PI. Hence, uterine artery doppler seems to be a better screening tool for early prediction of PIH. The third trimester umbilical artery PI with higher specificity (96%) and PPV (50%) can diagnose preeclampsia better. One patient had absent diastolic flow and she developed preeclampsia and IUGR. The combined uterine and umbilical artery doppler is a better screening modality as it has a higher sensitivity (75%) and NPV (99.26%). Conclusion: The uterine and umbilical artery Doppler velocimetry are potential tools for uteroplacental surveillance of high-risk pregnancies which can identify patients at risk and help in taking timely action to prevent complications.

Preeclampsia and Intrauterine growth restriction (IUGR) remains as the important causes for the neonatal and maternal complications leading to even death in some cases. Uterine artery Doppler USG can be done transvaginally or trans abdominal and performed in the 1st or 2nd trimester of the pregnancy to detect these complications Doppler waveform suggested the high vascular resistance to blood flow. In our present study, we conclude uterine artery Doppler indices as prognostic procedure for the preeclampsia and intrauterine growth restriction. A cross-sectional survey design with convenient sampling technique was used. Mixture of standardized and self-modified structured questionnaire was undertaken to determine the indices of pre eclampsia and IUGR by uterine artery. The data was collected from Bahria International Hospital, Lahore during the period of 9 months. This study was included 162 pregnant females with identification of the main uterine artery on a longitudinal scan lateral to the uterus.  Initial diastolic notch of right and left side of the uterine artery waveforms was recorded. At every antenatal checkup, urine was tested for protein and blood pressure readings were taken to identify preeclampsia. Further analysis was done dividing patients as normotensive and those patients developing hypertension after 30 weeks of gestation. After delivery neonates observed for IUGR by head circumference and body weight. The study was concluded that from the total sample size of 162 pregnant females who undergoes uterine artery Doppler, 34% females shows diastolic notch and almost all of these later diagnosed with preeclampsia and 19.8% deliver babies with IUGR. So, based on the study, we have concluded that uterine artery Doppler is helpful to provide diagnosis of preeclampsia and IUGR in early pregnancy.

Background: Pregnancy induced hypertension (PIH) is associated with adverse perinatal outcome. Multi vessel colour Doppler studies are useful in these cases for timely intervention. The aim of present study was to know the significance of umbilical, middle cerebral and uterine artery Doppler in PIH and to analyse their role in predicting perinatal outcome.Methods: This is a study of 150 pregnant women with pregnancy induced hypertension (PIH). These patients were evaluated with colour Doppler and were followed subsequently for any adverse perinatal outcome.Results: Out of 150 cases 70% of cases were found in 20-30 years age group. 98 cases had abnormal uterine artery Doppler indices accounting for 65.3%, while 52 cases had a normal Doppler index accounting for 34.3%. Out of 150 cases, 94 (64.6%) cases had abnormal middle cerebral artery. In our study 53 cases had abnormal umbilical artery Doppler indices accounting for 35.4%, while 97 cases had a normal Doppler index accounting for 64.6%. Out of 150 cases in our study 27 cases had Reversal of a wave in ductus venosus waveform that is in 18%. In this study total 5 cases (35.7%) of perinatal mortality were seen.Conclusions: The knowledge of various doppler parameters may help to improve pregnancy outcome and identification of PIH at earliest gestation age as compared to other antepartum test modalities.
