Twin pregnancies are commonly assessed using singleton growth and birth weight reference charts. This practice has led to a significant number of twins labelled as small for gestational age (SGA), causing unnecessary interventions and increased risk of iatrogenic preterm birth. However, the use of twin-specific charts remains controversial. This study aims to assess whether twin-specific estimated fetal weight (EFW) and birth weight (BW) charts are more predictive of adverse outcomes compared to singleton charts. Centiles of EFW and BW were calculated using previously published singleton and twin charts. Categorical data were compared using Chi-square or McNemar tests. The study included 1740 twin pregnancies, with the following perinatal adverse outcomes recorded: perinatal death, preterm birth <34 weeks, hypertensive disorders of pregnancy (HDP) and admissions to the neonatal unit (NNU). Twin-specific charts identified prenatally and postnatally a smaller proportion of infants as SGA compared to singleton charts. However, twin charts showed a higher percentage of adverse neonatal outcomes in SGA infants than singleton charts. For example, perinatal death (SGA 7.2% vs. appropriate for gestational age (AGA) 2%, p < 0.0001), preterm birth <34 weeks (SGA 42.1% vs. AGA 16.4%, p < 0.0001), HDP (SGA 21.2% vs. AGA 13.5%, p = 0.015) and NNU admissions (SGA 69% vs. AGA 24%, p < 0.0001), when compared to singleton charts (perinatal death: SGA 2% vs. AGA 1%, p = 0.029), preterm birth <34 weeks: (SGA 20.6% vs. AGA 17.4%, p = 0.020), NNU admission: (SGA 34.5% vs. AGA 23.9%, p < 0.000). There was no significant association between HDP and SGA using the singleton charts (p = 0.696). In SGA infants, according to the twin charts, the incidence of abnormal umbilical artery Doppler was significantly more common than in SGA using the singleton chart (27.0% vs. 8.1%, p < 0.001). In conclusion, singleton charts misclassify a large number of twins as at risk of fetal growth restriction. The evidence suggests that the following twin-specific charts could reduce unnecessary medical interventions prenatally and postnatally.

Serial ultrasonic measurement of the biparietal diameter is an unsatisfactory means of detecting the small-for-gestational age (SGA) fetus in twin pregnancies. A new two-stage ultrasound examination schedule, highly effective in detecting the SGA singleton fetus, has been evaluated prospectively in 31 twin pregnancies. The schedule comprises ultrasonic assessment of gestational age in early pregnancy, followed by measurement of the product of the crown–rump length and trunk area of both fetuses at 34–36 weeks. All Nineteen SGA twin fetuses were detected using this schedule; the technique offers several other advantages over serial biparietal cephalometry.

The aim of this work is to study the state of the problem of the development of small-for-gestational-age fetus and fetal growth restriction over the past 5 years. A review of randomized trials of the PubMed database for the period of 2015 to 2020 was carried out. Experts reached an agreement on the definition of diagnostic criteria for small-for-gestational-age fetus and fetal growth restriction, a clinically valid classification was created, and the main monitoring strategies were developed. Due to the different pathogenesis, fetal growth restriction is divided into early and late. The observation algorithm includes tests that have shown higher sensitivity and specificity. There is no single standard for the median weight and abdominal circumference of a fetus, indicators of the reference range for fetal Doppler. Smoking cessation and taking acetylsalicylic acid at a dose of 150 mg at high risk of preeclampsia is recommended to prevent the small-for-gestational-age fetus and fetal growth restriction. The pregnancy management algorithm includes Doppler ultrasound examination of the umbilical artery, cardiotocography. If this pathology occurs before 32 weeks of pregnancy, the blood flow in ductus venosus is additionally examined, and after 32 weeks of pregnancy, the middle cerebral artery blood velocities and cerebroplacental ratio are assessed. Indicators of Doppler velocimetry and cardiotocography, which serve as criteria for early termination of pregnancy, are developed, measures are proposed to improve neonatal outcomes prevention of respiratory distress syndrome at 2434 weeks of gestation, as well as magnesium therapy for fetal neuroprotection. The problems of preventing fetal growth restriction and the algorithm for monitoring pregnant women who do not have risk factors for small-for-gestational-age fetus, management tactics and indications for delivery while slowing fetal weight gain remain unresolved.
