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: Maternal – fetal circulation can be studied non-invasively by using doppler which can be used as a screening tool for fetal and maternal disease. Morphological changes in the uterine vasculature can be demonstrated by colour and pulsed doppler studies. The majority of the studies on uterine artery doppler have focused on a high risk population. The effectiveness of the uterine artery doppler to predict pre eclampsia or FGR in a low risk population has been shown to have a low to moderate predictive value1. Also the criteria for normal and abnormal uterine artery doppler continue to vary with no well accepted denition. Aim: To nd out the correlation between abnormal uterine artery doppler in the second trimester of pregnancy between 18-22 weeks, with the subsequent development of pre eclampsia and FGR. Materials and methods: This is a prospective cohort study carried out in the Department of Obstetrics and Gynecology for a period of one year. Antenatal patients in the age group of 18-35 years, between 18-22 weeks of gestation, who were included in the study underwent a uterine artery doppler. They were followed up until delivery. SPSS software was used to analyze the data. Results: 193 Obstetric patients in the age group 18-35 years were evaluated with uterine artery doppler. 77.7% had normal doppler indices. In the abnormal doppler group, 81.4% were in the high risk category and 48.8% of those with abnormal dopplers developed pre eclampsia and 34.9% with abnormal dopplers developed FGR. Conclusion: Patients with abnormal uterine artery doppler indices in the second trimester of pregnancy, had an 18 times increased risk of developing pre eclampsia and a 6 times increased risk of developing FGR when compared to those with normal doppler indices.

Aim. To evaluate the relationship between uterine artery Doppler indices and placental bed histopathology independent of clinical outcome. Materials and Methods. Uterine artery measurements were performed to 510 pregnant women who had come for routine antenatal care in 11–14th and 20–24th weeks. Placental bed biopsies from 141 cases were taken during cesarean section. Physiological changes and abnormal placental histology findings were investigated and compared with Doppler findings. Results. 116 biopsies were accepted as adequate biopsy and included in the study. Physiological changes were seen in 100 biopsies. Statistically significant higher PI and RI values in second trimester and higher notch rate in both trimesters were detected in the abnormal placental histology group (P<0,001). Conclusion. Strong relationship between uterine artery Doppler indices and preeclampsia or intrauterine growth retardation has been shown in previous studies. In our study, we concluded that there is significant relationship between Doppler findings and placental bed histopathology independent of clinical course.
