Background and Objectives: To evaluate the role of Doppler ultrasonography in predicting the perinatal outcome in high-risk pregnancy and to establish its role in management of high-risk pregnancy. Materials and Methods: The present study is a prospective study of Doppler ultrasound evaluation of uterine artery, umbilical artery and middle cerebral artery in 100 high-risk pregnant women, performed between 28 and 34 weeks of gestation. Doppler index Pulsatility index (PI) for each above mentioned artery and cerebro-placental ratio (CPR) will be calculated. Doppler Pulsatility index for the corresponding gestational age were compared with the reference values. The results of the Doppler ultrasound and AFI will be used for analysis of mode of delivery and perinatal outcome in the form of birth weight, APGAR score, NICU admission, perinatal mortality. Results: Among newborns 46(46%) were admitted to NICU, 64(64%) of neonates had birth weight less than 2.5kg, there were 17 perinatal deaths. Of the 17 perinatal deaths, 2 cases had reverse end diastolic Flow (REDF) and 12 had absent end diastolic Flow (AEDF). Uterine artery PI was most sensitive(72.3%) than Umbilical artery PI(sensitivity 59.6%) and MCA PI(sensitivity 68.1%). Diagnostic accuracy of Cerebroplacental ratio (accuracy71%) was better than Umbilical artery PI (accuracy 65%) and MCA PI(accuracy 70%) in predicting adverse outcomes. Conclusion: Triple vessel colour Doppler sonography is very useful in high-risk pregnancy diagnosis and in predicting perinatal outcome.

A Prospective Study

This was a prospective study conducted in pregnant patients with high risk factors who got admitted in the Department of Obstetrics and Gynaecology at Care Hospital, Jamnagar during the period from May 2018 to September 2020. Background: High-risk pregnancies causes many adverse perinatal outcomes. Doppler ultrasound is a non-invasive technique to study the feto-maternal circulation to guide the clinical management. Objective: This study aims at evaluating the role of colour Doppler in high-risk pregnancies and their perinatal outcome. Materials and Methods: This was a prospective study carried out for 29 months in the Department of Radiology with antenatal women in the age group of 18-35 years with singleton pregnancy of gestational age of <28 weeks to >35 weeks having high-risk factors considered in study. The risk factors considered were pregnancy induced hypertension (PIH), gestational diabetes, anemia, oligohydramnios, polyhydramnios and IUGR. Doppler study of umbilical artery and fetal middle cerebral artery (MCA) arteries was done and amniotic fluid index (AFI) was measured. Parameters in the form of resistive index, pulsatility index, and systolic/diastolic ratio were taken. obstetric history was taken with regular interval follow up. Results: The study was carried out with 50 patients. High-risk pregnancy was more common in the age group of 21-25 years. The most common high-risk factor in pregnancy was oligohydramnios which accounted for 30% of cases. Out of 50 high-risk pregnancies, 5 (10 %) of cases resulted in intrauterine growth restriction (IUGR). Out of 50 high-risk cases, in 36 cases, umbilical artery findings were abnormal. 3 patients had intrauterine death (IUD) and 27 patients had poor perinatal outcome. Umbilical artery abnormality showed significant sensitivity and negative predictive value for adverse (poor + IUD) perinatal. Correlation was seen between high risk pregnancy and need of emergency caesarean section and induction and associated adverse perinatal outcome. Conclusion: Combination of different arterial waveform study enhance the diagnostic accuracy in identifying those intrauterine growth restricted foetuses that were at risk. Keywords: Colour Doppler, high risk pregnancy, perinatal outcome.

Background: The uterine artery Doppler has potentials for screening for complications of impaired placentation. The purpose of study was to assess the role of uterine artery color Doppler waveform analysis in second trimester for the prediction of preeclampsia in a high-risk pregnancy between 18-24 weeks of gestation.Methods: 100 women with moderate or high-risk factors for developing preeclampsia reporting to Obstetrics and Gynaecology department of Government Medical College and Hospital, Sector 32, Chandigarh were enrolled for present study. Transabdominal uterine artery doppler measurements was done at 18-24weeks of gestation in these patients. Doppler . The Doppler indices generated automatically from the machine , the Pulsatility Index (PI), Resistance Index (RI) , presence or absence of diastolic notch and S/D Ratio were recorded, and average was calculated.Results: Out of 100 patients there were 46 primigravidas with no additional risk factors, 22 pateints with two or more risk factors and there were no patients who had three or more risk factors in present study population. Preeclampsia is seen more commonly in primigravida and primigravida is considered as moderate risk factor for preeclampsia. It was found that an elevated second trimester uterine artery RI was significantly associated with developing preeclampsia later in pregnancy. The sensitivity and specificity of uterine artery Doppler velocimetry were found to be 84% and 55% respectively. Receiver operator characteristics (ROC) curves were created to demonstrate the prognostic value of RI and PI of uterine artery doppler indices at 18-24 weeks of gestation for the development preeclampsia. In addition, there were statistically significant positive correlations between mean RI of uterine artery doppler study and patients who developed preeclampsia. With a sensitivity of 84.21% it could identify 31% of the cases of preeclampsia at a false positive rate of 44.4%.Conclusions: Uterine artery doppler study can be used as a predictor of moderate strength for preeclampsia.

Background: High-risk pregnancies are associated with adverse perinatal and maternal outcomes. Aim: To know the overall perinatal outcome in high-risk pregnancies. Methods: Present observational study was conducted in the Obstetrics and Gynecology department of a rural tertiary center of Northern India over eight months (February-October 2018) on 3,085 antenatal women at gestation ≥ 28 weeks with 1,309 high-risk cases and 1,776 normal pregnancy cases after Institutional ethical committee approval and informed written consent from the participants. The demographic features including age, gravidity, parity, gestation, high-risk factors, the onset of labor, mode of delivery of all the selected antenatal women at gestation ≥ 28 weeks were recorded on a preformed datasheet by trained staff. All the participants were observed till delivery and the perinatal outcome was recorded. Statistical analysis was done using software SPSS 22.0 version and a p-value <0.05 was considered statistically significant. Results: Of total 1,309 high-risk pregnancies, 365(27.9%) were preterm, 936(71.5%) term and eight (0.6%) post-term cases. Of 1,309 neonates delivered, 66(5.04%) were intra-uterine dead fetuses, 1,243 live fetuses, of which nine (0.7%) had intrapartum still-birth, 278(22.4%) required neonatal intensive care unit admission, 70(5.6%) intubated, 238(19.1%) needed oxygen support, 343(27.6%) developed complications, while 11(0.9%) had early neonatal deaths. The average birth weight of neonates delivered to high-risk mothers was 2.47±0.571 Kg with 271(20.7%) neonates having low birth weight (<2.5 Kg). Of all high-risk factor Hypertensive disorders of pregnancy, Antepartum hemorrhage, Anemia, Gestational diabetes mellitus, Intra-uterine growth restriction, oligohydramnios was significantly associated with adverse perinatal outcomes (p<0.05). High-risk pregnancy was associated with preterm births, low birth weight, NICU admission, intubation, complications, neonatal deaths, still-births as compared to normal pregnancy. Most common neonatal complication was the low birth weight (20.7%) followed by Respiratory distress syndrome (17.6%), prematurity (13.1%). Conclusion: High-risk pregnancy was associated with an adverse overall perinatal outcome with increased risk of perinatal morbidities and mortalities.

Background: Hypertensive disorders are the common cause of maternal death which affecting nearly 5-10% of pregnancies all over the world. Pre-eclampsia develop from inadequate trophoblast invasion of the maternal spiral arteries and Doppler values permits non-invasive evaluation of uteroplacental circulation and is of great importance in the management of high risk pregnancies. The aim of the study was to assess the findings of Doppler data in predicting pre-eclampsia and comparison of the efficacy of uterine artery Doppler and umbilical artery Doppler.Methods: The study comprises of 100 women with high risk pregnancy attending antenatal clinic at Geetanjali Medical College and Hospital, Udaipur were subjected to uterine and umbilical artery Doppler Study. Women with high risk pregnancy between 26-32 weeks of gestation were studied with colour Doppler. This was a prospective study over a period of 1 year from 2015-2016.Results: The results of the study revealed that 5 out of 100 participants developed pre-eclampsia. Out of different parameters, notch is the best predictor of pre-eclampsia with high sensitivity and highest PPV for uterine artery Doppler and S/D ratio is considered to be best indicator for umbilical artery Doppler. Regarding efficacy, umbilical artery Doppler is more predictive than uterine Doppler.Conclusions: Doppler study can be used for the prediction of pre-eclampsia to reduce maternal morbidity and mortality.
