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.

Introduction. Impaired placentation and inadequate trophoblast invasion have been associated with the etiology of many pregnancy complications and have been correlated with the first trimester uterine artery resistance. Previous studies have shown the benefits of yoga in improving pregnancy outcomes and those of yogic visualization in revitalizing the human tissues.Methods. 59 high-risk pregnant women were randomized into yoga (n= 27) and control (n= 32) groups. The yoga group received standard care plus yoga sessions (1 hour/day, 3 times/week), from 12th to 28th week of gestation. The control group received standard care plus conventional antenatal exercises (walking). Measurements were assessed at 12th, 20th, and 28th weeks of gestation.Results. RM-ANOVA showed significantly higher values in the yoga group (28th week) for biparietal diameter (P= 0.001), head circumference (P= 0.002), femur length (P= 0.005), and estimated fetal weight (P= 0.019). The resistance index in the right uterine artery (P= 0.01), umbilical artery (P= 0.011), and fetal middle cerebral artery (P= 0.048) showed significantly lower impedance in the yoga group.Conclusion. The results of this first randomized study of yoga in high-risk pregnancy suggest that guided yogic practices and visualization can improve the intrauterine fetal growth and the utero-fetal-placental circulation.

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.

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.
