Abstract Background Affecting approximately 10% of pregnancies, fetal growth restriction (FGR), is the most important cause of perinatal mortality and morbidity. Impaired placental function and consequent mal-perfusion of the placenta is the leading cause of FGR. Although, screening for placental insufficiency based on uterine artery Doppler measurement is well established, there is no treatment option for pregnancies threatened by FGR. The organic nitrate pentaerithrityl tetranitrate (PETN) is widely used for the treatment of cardiovascular disease and has been shown to have protective effects on human endothelial cells. In a randomized placebo controlled pilot-study our group could demonstrate a risk reduction of 39% for the development of FGR, and FGR or death, by administering PETN to patients with impaired uterine artery Doppler at mid gestation. To confirm these results a prospective randomized placebo controlled double-blinded multicentre trial was now initiated. Method The trial has been initiated in 14 centres in Germany. Inclusion criteria are abnormal uterine artery Doppler, defined by mean PI > 1.6, at 190 to 226 weeks of gestation in singleton pregnancies. Included patients will be monitored in 4-week intervals. Primary outcome measures are development of FGR (birth weight < 10th percentile), severe FGR (birth weight < 3rd centile) and perinatal death. Placental abruption, birth weight below the 3rd, 5th and 10th centile, development of FGR requiring delivery before 34 weeks` gestation, neonatal intensive care unit admission, and spontaneous preterm delivery < 34 weeks` and 37 weeks` gestation will be assessed as secondary endpoints. Patient enrolment was started in August 2017. Results are expected in 2020. Discussion During the past decade therapeutic agents with possible perfusion optimizing potential have been evaluated in clinical trials to treat FGR. Meta-analysis and sub-analysis of trials targeting preeclampsia revealed ASS to have a potential in reducing FGR. Phosphodiesterase-type-5 inhibitors have recently been tested in a worldwide RCT for therapy of established FGR, failing to show an effect on neonatal outcome. The ongoing multicenter trial will, by confirming our previous results, finally provide a therapeutic option in cases at risk for FGR.

Uterine Artery Doppler

Objective To perform a comprehensive review of the current evidence on the role of uterine artery Doppler, isolated or in combination with other markers, in screening for preeclampsia (PE) and fetal growth restriction (FGR) in the general population. The review included recently published large cohort studies and randomized trials. Methods A search of the literature was conducted using Medline, PubMed, MeSH and ScienceDirect. Combinations of the search terms “preeclampsia,” “screening,” “prediction,” “Doppler,” “Doppler velocimetry,” “fetal growth restriction,” “small for gestational age” and “uterine artery” were used. Articles in English (excluding reviews) reporting the use of uterine artery Doppler in screening for PE and FGR were included. Results Thirty articles were included. As a single predictor, uterine artery Doppler detects less than 50% of the cases of PE and no more than 40% of the pregnancies affected by FGR. Logistic regression-based models that allow calculation of individual risk based on the combination of multiple markers, in turn, is able to detect ∼ 75% of the cases of preterm PE and 55% of the pregnancies resulting in small for gestational age infants. Conclusion The use of uterine artery Doppler as a single predictive test for PE and FGR has poor accuracy. However, its combined use in predictive models is promising, being more accurate in detecting preterm PE than FGR.

Flow Velocimetry

With the ascendancy of biophysical assessment with Doppler velocimetry, and the establishment of routine scan dating in early pregnancy, there needs to be a radical re-think of the role of ultrasound biometry in the definition and assessment of fetal growth restriction (FGR).Doppler flow velocimetry of the umbilical artery has proven its value in defining the FGR fetus. It is more useful than cardiotocography (CTG) or biophysical profile scoring. However, the sensitivity of any test depends on the prevalence of the condition being looked for. While Doppler is of value in fetuses which are small-for-gestational age (SGA), it is less useful in predicting growth restriction or adverse outcome in the general population. The question is therefore, how to detect those pregnancies for which further fetal assessment is indicated.
