Adverse Perinatal Outcome

Background: Fetal surveillance of the pregnancies that are complicated by IUGR is essential to improve fetal outcome. Colour Doppler studies of uteroplacental and fetoplacental circulation are useful in identification of hypoxemic status of the fetus and allows timely intervention in at risk fetuses. The present study was aimed to know the significance of colour Doppler studies in intrauterine growth restriction cases and to correlate with the perinatal outcome thus to offer better strategies for early diagnosis of compromised fetus and timely intervention.Methods: This was a prospective study of 125 singleton pregnancies in the third trimester with IUGR. The results of last Doppler ultrasound within one week of delivery were used for analysis. Adverse perinatal outcome was studied in the form of emergency cesarean section for fetal distress, meconium stained amniotic fluid, Apgar at 5 min <7, NICU admission and perinatal mortality (stillbirths and neonatal death). Sensitivity, Specificity, Positive Predictive Value (PPV), Negative Predictive Value (NPV) and Diagnostic accuracy of various Doppler parameters were calculated after comparing with standard.Results: In the present study 63 patients had one or more adverse perinatal outcome parameter. The diagnostic accuracy of umbilical artery was more (71.20%) than other parameters in predicting adverse perinatal outcome. Middle cerebral artery RI was having highest specificity and positive predictive value of 100% than any other parameter in predicting adverse perinatal outcome. Patients with AEDF and REDF had 33.3% and 50% perinatal deaths respectively.Conclusions: Middle cerebral artery Doppler studies shown more specificity and positive predictive value than umbilical artery Doppler in prediction of adverse perinatal outcome.

Induced Hypertension

Background: Pregnancy induced hypertension (PIH) is associated with adverse perinatal outcome. Multi vessel color 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 studies in PIH and to analyse its role in predicting perinatal outcome.Methods: This was a prospective study of 106 singleton pregnancies in the third trimester with PIH. The results of last Doppler ultrasound within one week of delivery were used for analysis. Adverse perinatal outcome was studied in the form of emergency cesarean section for fetal distress, meconium stained amniotic fluid, Apgar at 5 min <7, NICU admission and perinatal mortality (stillbirths and neonatal death). Sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV) and diagnostic accuracy of various Doppler parameters were calculated after comparing with standard.Results: In the present study specificity and diagnostic accuracy of all Doppler ultrasound parameters was high in predicting adverse perinatal outcome. Cerebroplacental ratio showed highest specificity (98.55%), PPV (94.44%) and diagnostic accuracy (80.19%) in predicting adverse perinatal outcome and it is better than MCA PI and UA PI alone. Uterine artery Doppler evaluation also gives additional information in predicting adverse perinatal outcome.Conclusions: Amongst various Doppler parameters cerebroplacental index (MCA/UA PI) is best predictor of adverse perinatal outcome.

Objective: To determine diagnostic accuracy of systolic/diastolic ratio and cerebro-placental index in predicting adverse perinatal outcome among patients in preeclampsia. Study Design: Cross-sectional validation study. Place and Duration of Study: Department of Obstetrics and Gynaecology, Pak Emirates Military Hospital, Rawalpindi, from Jun to Dec 2017. Methodology: A total of 191 patients with preeclampsia were included. Doppler ultrasound (including doppler wave forms obtained from free floating portion of umbilical artery and doppler waveform from middle cerebral artery at the level of circle of Willis) examination was done after gestational age 30 weeks and Doppler study repeated at 2-4 weeks interval depending on severity of preeclampsia and abnormalities of waveform. Cases were followed and results of last Doppler examination within 10 days of delivery were considered and perinatal outcome noted. Results: The sensitivity, specificity, positive predictive value, negative predictive value and diagnostic accuracy of systolic/diastolic ratio in predicting adverse perinatal outcome among patients in preeclampsia, keeping actual adverse perinatal outcome as reference standard was 82.35%, 86.52%, 87.50%, 81.05% and 84.29% respectively. The sensitivity, specificity, positive predictive value, negative predictive value and diagnostic accuracy of cerebro-placental index in predicting adverse perinatal outcome among patients in preeclampsia, keeping actual adverse perinatal outcome as reference standard was 78.67%, 92.24%, 86.76%, 86.99% and 86.91% respectively. Conclusion: The diagnostic accuracy of systolic/diastolic ratio, cerebro-placental index in predicting adverse perinatal outcome among patients in preeclampsia is quite high.

Uteroplacental Blood Flow

Background: Intrauterine growth restriction is a complication that arises due to decrease in uteroplacental blood flow during pregnancy. This decrease is associated with a pathological condition of spiral arteries thought to arise during placentation in first trimester of pregnancy. Thus, it might be possible to predict the development of these conditions by assessing uteroplacental blood flow in pregnancy with colour Doppler. The aim of the study was to assess the findings of Doppler data in predicting IUGR and finding the best predictors of IUGR in uterine and umbilical artery Doppler.Methods: In this prospective study, total of 100 women with high risk pregnancy attending Department of Obstetrics and Gynecology 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 study was carried over a period of 1 year from 2015-2016.Results: Out of total 100 patients, 8 were found to have IUGR. Out of different parameters, Notch is the best indicator with high sensitivity and highest positive predictive value (PPV) of 50% followed by combination of parameter as it had the highest sensitivity of 62.5% for uterine artery Doppler. S/D Ratio is the best indicator with high sensitivity and highest positive predictive value (PPV) of 25% and 40% respectively followed by RI with highest sensitivity of 42.86% for umbilical artery Doppler.Conclusions: Value of Doppler assessment of uteroplacental circulation in predicting IUGR and is very useful in improving pregnancy outcome.

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.

Control Study

Background: Intrauterine growth restriction (IUGR) is a major and silent cause of perinatal morbidity and mortality. Rate of IUGR in developing countries is 6 times higher than that of developed countries. 14 to 20 million infants are affected with IUGR in developing countries annually. The highest incidence is found in south central Asia (33%) and India (21%). Aim of study was to evaluate the role of early 3rd trimester ultrasound in diagnosis and role of color Doppler in prediction of adverse perinatal outcome in IUGR.Methods: A prospective case-control study was conducted on 720 women admitted in GMH Rewa for one year. 360 antenatal cases diagnosed as IUGR on ultrasound were taken as study group, same number of non IUGR cases were taken as control. Study cases were followed with Doppler. The umbilical artery pulsatility index (UA PI), middle cerebral artery pulsatility index (MCA PI) and cerebro-placental ratio were calculated and the results were analysed.Results: Inferences drawn from the study were: rate of caesarean section was significantly higher (31%) in study group, perinatal outcome was poor in more number of cases (10.8%) in study group than the control group (3.4%), and the sensitivity and specificity of cerebroplacental ratio was more reliable indicator in comparison to that of UA PI and MCA PI in prediction of adverse perinatal outcome.Conclusions: Looking at the high burden of IUGR cases in our country and its adverse effects on perinatal outcome, if early third trimester ultrasound is made mandatory for all pregnant women, most of the IUGR cases can be detected and managed timely and perinatal outcome can be significantly improved.
