Context.— Fetal growth restriction is a risk factor for intrauterine fetal death. Currently, definitions of fetal growth restriction in stillborn are heterogeneous. Objectives.— To develop a consensus definition for fetal growth restriction retrospectively diagnosed at fetal autopsy in intrauterine fetal death. Design.— A modified online Delphi survey in an international panel of experts in perinatal pathology, with feedback at group level and exclusion of nonresponders. The survey scoped all possible variables with an open question. Variables suggested by 2 or more experts were scored on a 5-point Likert scale. In subsequent rounds, inclusion of variables and thresholds were determined with a 70% level of agreement. In the final rounds, participants selected the consensus algorithm. Results.— Fifty-two experts participated in the first round; 88% (46 of 52) completed all rounds. The consensus definition included antenatal clinical diagnosis of fetal growth restriction OR a birth weight lower than third percentile OR at least 5 of 10 contributory variables (risk factors in the clinical antenatal history: birth weight lower than 10th percentile, body weight at time of autopsy lower than 10th percentile, brain weight lower than 10th percentile, foot length lower than 10th percentile, liver weight lower than 10th percentile, placental weight lower than 10th percentile, brain weight to liver weight ratio higher than 4, placental weight to birth weight ratio higher than 90th percentile, histologic or gross features of placental insufficiency/malperfusion). There was no consensus on some aspects, including how to correct for interval between fetal death and delivery. Conclusions.— A consensus-based definition of fetal growth restriction in fetal death was determined with utility to improve management and outcomes of subsequent pregnancies.

Massive subchorionic thrombohematoma (MST), termed Breus’ mole, is a rare condition in which a large maternal blood clot separates the chorionic plate from the villous chorion. Common complications of MST include fetal growth restriction, preeclampsia, and intrauterine fetal death. Here, we present a case of a 17-year-old Japanese woman referred to our institution at 21 weeks of gestation. Ultrasound examination revealed a large placental mass with mixed high and low echogenicity measuring approximately 7.6 cm in thickness. Doppler examination showed absence of end-diastolic velocity of the umbilical artery. At 22 weeks of gestation, the patient had a stillbirth weighing 138g. The placenta weighed 502 g and was 8 cm thick, and the total blood loss was 270 g. Macroscopic examination revealed that a subchorionic blood clot measuring 12 cm × 5 cm covered a large portion of the placenta with well-defined margins on the fetal surface. Microscopic examination revealed an intervillous hematoma and fibrinous deposits directly beneath the chorionic plate with adjacent compressive effects. Based on these findings, MST was diagnosed. Because MST is rare, it must be considered in the differential diagnosis of parental conditions. Magnetic resonance imaging can be optimal for diagnosing MST when ultrasound diagnosis is difficult.

AbstractObjective:To analyze the accuracy of ultrasound prediction of birth weight discordance (BWD) and the influence of chorionicity and fetal growth restriction (FGR) on ultrasound performance.Methods:Retrospective analysis of 176 twin pregnancies at a Portuguese tertiary center, between 2008 and 2014. Last ultrasound biometry was recorded. Cases with delivery before 24 weeks, fetal malformations, interval between last ultrasound and deliver >3 weeks, twin-to-twin transfusion syndrome and monoamniotic pregnancies were excluded. The accuracy of prediction of BWD was assessed using the area under the receiver-operating characteristics curve (AUC).Results:BWD ≥20% was present in 21.6% of twin pregnancies. EBW had the best predictive performance for BWD (AUC 0.838, 95%CI 0.760–0.916), with a negative predictive value of 86.9% and a positive predictive value of 51.3%. Chorionicity did not influence ultrasound performance. None of the biometric variables analyzed was predictive of BWD in pregnancies without FGR.Conclusion:The accuracy of ultrasound in the prediction of BWD is limited, particularly in pregnancies without fetal growth restriction. Clinical decisions should not rely on BWD alone.

The placenta is essential for sustaining the growth of the fetus during gestation, and defects in its function result in fetal growth restriction or, if more severe, fetal death. Several molecular pathways have been identified that are essential for development of the placenta, and mouse mutants offer new insights into the cell biology of placental development and physiology of nutrient transport.

Background: Fetal Growth Restriction (FGR) is the single largest contributing factor to perinatal morbidity in non-anomalous foetuses. Synonymous with Intrauterine Growth Restriction (IUGR), it is defined as an estimated fetal weight less than the10th percentile. Obstetric Doppler has helped in early detection and timely intervention in babies with FGR with significant improvements in perinatal outcomes.  Hence, authors evaluated the maternal risk factors and diagnosis-delivery intervals and perinatal outcomes in FGR using Doppler.Methods: This research conducted in a tertiary care hospital in South Kerala included 82 pregnant women who gave birth to neonates with birth weight less than the 10th percentile over a period of1 year (Jan 1, 2017-Dec 31, 2017). Socio-demographic, maternal risk, Diagnosis- delivery interval in FGR and neonatal morbidities were studied.Results: Mean GA at diagnosis in weeks was 34.29 and 35.19 respectively for abnormal and normal Doppler respectively (p value-0.032). The mean birthweight in Doppler abnormal FGR was 272.34 g lesser than in Doppler normal group (p value-0.001). Growth restricted low birth weight neonates had Doppler   pattern abnormalities (p value-0.0009). FGR <3rd percentile and AFI <5 had abnormal Doppler (OR:6.7). Abnormal biophysical profile (OR:14) and Non-Reactive NST (OR:3.5) correlated with abnormal Doppler. Growth restricted with normal Doppler had shorter NICU stays than with abnormalities (p value-0.003). Term FGR went home early than early preterm. (p value-0.001).Conclusions: Abnormal Doppler velocimetry is significantly associated with earlier FGR detection, shorter decision- delivery interval, reduction in the mean birthweight and longer NICU stay. Hence, Umbilical artery Doppler and Cerebroplacental index is an integral part of in-utero fetal surveillance to identify impending fetal hypoxia, appropriate management, optimising the timing of delivery and improve perinatal health in FGR.
