Colour Doppler Study of Umbilical Artery in Antenatal Women with Severe Preeclampsia and Foetal Outcome

Background: The development of doppler ultrasonographic technology has provided an opportunity to obtain a qualitative and quantitative assessment of maternal and foetal circulation using a non-invasive method. It has been proved by many studies that doppler has a very important role in screening of high-risk pregnancies. Objective of this study was to evaluate the role of colour doppler study in normal and high-risk pregnancy in relation to perinatal outcome.Methods: A prospective study was done including 75 women with high risk pregnancy and 75 normal pregnant women during the period October 2018 to September 2019 in hospitals attached to Bangalore Medical College and Research Institute. Doppler examination was done after recording patients’ history, clinical examination and ultrasound. Results were analysed and conclusions were made.Results: Out of the 22 patients with PIH, 20 patients had abnormal umbilical artery S/D ratio and all 22 had abnormal MCA PI. Out of 12 patients with diabetes, 10 had abnormal umbilical artery S/D ratio. All the patients with IUGR had abnormal umbilical artery S/D ratio and abnormal MCA PI.Conclusions: Colour doppler flow velocimetry done repeatedly can predict adverse foetal events with a great degree of accuracy.

Doppler Study

Normal fetal growth and development depends on adequate perfusion of the intervillous space through the maternal spiral arterioles. Reduced perfusion is associated with asymmetrical retardation of the fetal growth and fetal hypoxia that is the major cause of perinatal mortality. Pregnancy induced hypertension (PIH) remains the major cause of maternal and perinatal morbidity and mortality. With the help of colour Doppler, the identification of vessels that are evaluated for Doppler study can become simple1. Hence role of Doppler examination has become indispensable in screening, diagnosis and management of PIH and IUGR cases2. With the aid of colour Doppler, IUGR can be diagnosed before it is clinically evident. In the present study, we examined flow velocity waveforms in uteroplacental (uterine artery and umbilical artery) and fetoplacental (middle cerebral artery) circulations in both normal pregnancy3 and in situations of suspected placental insufficiently such as PIH and IUGR pregnancies4. Subsequently result in birth of growth retarded infant, to derive pathophysiological information about placental flow resistance and assess the diagnostic potential of this measurement.

Optimal Site

While ultrasonography is widely performed prior to biopsy, colour Doppler examination is often used only to discover post-biopsy complications. Aim of this paper was to evaluate the usefulness of colour Doppler examination in planning the optimal site of puncture for renal biopsy. Present analysis includes 561 consecutive percutaneous renal biopsies performed from the same operator. Until August 2000 332 biopsies were performed after a preliminary ultrasonography (Group A). From September 2000, 229 patients underwent even a preliminary colour Doppler study (Group B). Postbioptic bleeding were categorized as minor (gross hematuria or subcapsular perinephric hematoma < 4 cmq of greater diameter) or major (hematoma >4 cmq of greater diameter; requiring blood transfusion or invasive procedures; leading to acute renal failure, urine tract obstruction, septicaemia, or death). Major complications were seen in 2.1% in Group A while in Group B only one case was reported (0.43%). Minor clinically significant complications occur in 7.8% in Group A and in 3.4% of cases of Group B. Colour Doppler reduced drastically the incidence of complications observed before the introduction of routine colour Doppler examination prior to biopsy. In our opinion, these data support the use of preliminary colour Doppler study when a biopsy is planned.

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.

Vertex Presentation

Background: Pre-eclampsia and IUGR are two conditions resulting from defective trophoblastic invasion of spiral arteries and an increase in vascular resistance in uteroplacental circulation. Doppler offers a non-invasive tool for evaluation of fetoplacental blood flow and correlate with fetal compromise giving early warning sign of fetal distress.Methods: The study was conducted in Command Hospital, Lucknow in 100 singleton pregnancies with vertex presentation between 28-40 weeks of gestation with severe preeclampsia and/or IUGR. Doppler analysis of UA and MCA was done. Pregnancies were terminated depending on clinical condition and Doppler results.Results: Abnormal Umbilical artery S/D ratio had strong statistical correlation with poor perinatal outcome. Elevated RI had 100% sensitivity in predicting APGAR<7 at 5 minutes. Elevated PI values was statistically significant in all parameters (except NICU stay>48hrs) in predicting poor perinatal outcome. PI values had highest sensitivity for predicting low APGAR values and highest specificity for predicting NICU admission. AEDF and REDF also correlated with adverse perinatal outcome. MCA S/D ratio had a high sensitivity (96.8%) in determining NICU stay>48h and specificity (70%) in determining NICU admissions. RI had highest sensitivity (71.8%) for NICU stay >48hrs and highest specificity for predicting NICU admissions (76.5%). MCA PI had a sensitivity of 66.6% in determining APGAR<7 at 5min and a specificity of 78.7% in determining NICU admissions. CPR had the highest sensitivity (100%) among all indices.Conclusions: The study showed an adverse fetal outcome in cases of severe preeclampsia and or IUGR which showed abnormal Doppler results and thereby help to determine the optimal time for delivery.
