BACKGROUND: The cerebroplacental ratio has been proposed as a marker of failure to reach growth potential near term. Low cerebroplacental ratio, regardless of the fetal size, is independently associated with the need for operative delivery for presumed fetal compromise and with neonatal unit admission at term. OBJECTIVE: The main aim of this study was to evaluate whether the cerebroplacental ratio at term is a marker of reduced fetal growth rate. The secondary aim was to investigate the relationship between a low cerebroplacental ratio at term, reduced fetal growth velocity, and adverse pregnancy outcome...

Antepartum fetal surveillance with Doppler ultrasound of umbilical artery has shown significant diagnostic efficacy in identifying fetal compromise in pregnancies complicated with fetal growth restriction and preeclampsia. Moreover, randomized clinical trials and their meta-analyses have shown its effectiveness in decreasing perinatal mortality (level I evidence). This is the only antepartum fetal test that has shown this level of effectiveness. There is no evidence that routine Doppler in low-risk pregnancies improves the outcome...

OBJECTIVE: To assess Doppler flow velocity in fetal, uteroplacental, and maternal arteries before and after betamethasone therapy among singleton pregnancies complicated by fetal growth restriction (FGR). METHODS: A prospective, longitudinal, multicenter study was conducted at three university-affiliated hospitals in Tehran, Iran, between January 1 and November 30, 2013. The inclusion criteria were FGR, a gestational age of 24-34 weeks, no fetal anomalies, and no previous betamethasone therapy...

The ductus venosus has a central role in the distribution of highly oxygenated umbilical venous blood to the heart. Its waveform is related to the pressure-volume changes in the cardiac atria and it is therefore important in the monitoring of any fetal condition that may affect forward cardiac function. The cardiovascular parameters that can influence forward cardiac function include afterload, myocardial performance and preload. Decreased forward flow during atrial systole (a-wave) is the most sensitive and ubiquitous finding when any of these parameters is affected...

OBJECTIVE: The objective of the Prospective Observational Trial to Optimize Pediatric Health in Intrauterine Growth Restriction (IUGR) (PORTO Study), a national prospective observational multicenter study, was to evaluate which sonographic findings were associated with perinatal morbidity and mortality in pregnancies affected by growth restriction, originally defined as estimated fetal weight (EFW) <10th centile. STUDY DESIGN: Over 1100 consecutive ultrasound-dated singleton pregnancies with EFW <10th centile were recruited from January 2010 through June 2012...

Forty-nine obstetricians from three European countries were asked when they would advise delivery for a preterm fetus failing to thrive in utero, given various gestational ages, and a range of either umbilical artery Doppler flow velocity waveforms or CTG variability measures. Their responses indicated a wide area of disagreement about the correct timing of delivery, and a willingness to randomize patients to clinical trials of management. The area of uncertainty corresponded to the gestational age and Doppler bands at which participants have been entered to the pilot phase of a randomised trial of timed delivery, the Growth Restriction Intervention Trial (GRIT)...

OBJECTIVES: Few data exist for counseling and perinatal management of women after an antenatal diagnosis of early-onset fetal growth restriction. Yet, the consequences of preterm delivery and its attendant morbidity for both mother and baby are far reaching. The objective of this study was to describe perinatal morbidity and mortality following early-onset fetal growth restriction based on time of antenatal diagnosis and delivery. METHODS: We report cohort outcomes for a prospective multicenter randomized management study of fetal growth restriction (Trial of Randomized Umbilical and Fetal Flow in Europe (TRUFFLE)) performed in 20 European perinatal centers between 2005 and 2010...

BACKGROUND: No consensus exists for the best way to monitor and when to trigger delivery in mothers of babies with fetal growth restriction. We aimed to assess whether changes in the fetal ductus venosus Doppler waveform (DV) could be used as indications for delivery instead of cardiotocography short-term variation (STV). METHODS: In this prospective, European multicentre, unblinded, randomised study, we included women with singleton fetuses at 26-32 weeks of gestation who had very preterm fetal growth restriction (ie, low abdominal circumference [<10th percentile] and a high umbilical artery Doppler pulsatility index [>95th percentile])...

OBJECTIVE: We sought to provide evidence-based guidelines for utilization of Doppler studies for fetuses with intrauterine growth restriction (IUGR). METHODS: Relevant documents were identified using PubMed (US National Library of Medicine, 1983 through 2011) publications, written in English, which describe the peripartum outcomes of IUGR according to Doppler assessment of umbilical arterial, middle cerebral artery, and ductus venosus. Additionally, the Cochrane Library, organizational guidelines, and studies identified through review of the above were utilized to identify relevant articles...
