Fetal biometry, estimation of gestational age, assessment of fetal growth

Small-for-gestational-age (SGA) infants have been associated with increased risk of adverse perinatal outcomes (APOs). In this work, we assess the predictive ability of the ultrasound-estimated percentile weight (EPW) at 35 weeks of gestational age to predict late-onset SGA and APOs, according to six growth standards, and whether the ultrasound–delivery interval influences the detection rate. To this purpose, we analyze a retrospective cohort study of 9585 singleton pregnancies. EPWs at 35 weeks were calculated to the customized Miguel Servet University Hospital (MSUH) and Figueras standards and the non-customized MSUH, Fetal Medicine Foundation (FMF), INTERGROWTH-21st, and WHO standards. As results of our analysis, for a 10% false positive rate, the detection rates for SGA ranged between 48.9% with the customized Figueras standard (AUC 0.82) and 60.8% with the non-customized FMF standard (AUC 0.87). Detection rates to predict SGA by ultrasound–delivery interval (1–6 weeks) show higher detection rates as intervals decrease. APOs detection rates ranged from 27.0% with FMF to 7.9% with the Figueras standard. In conclusion, the ability of EPW to predict SGA at 35 weeks is good for all standards, and slightly better for non-customized standards. The APO detection rate is significantly greater for non-customized standards.

ABSTRACT Introduction Accurate assessment of gestational age and fetal growth using ultrasound is imperative in providing good quality antenatal and perinatal care. It provides a noninvasive reliable estimate of the gestational age and serves as a baseline upon which interval fetal growth can be assessed throughout pregnancy. Aim The present study was undertaken to assess the relationship between gestational age and fetal foot length and to derive a nomogram correlating gestational age in weeks with fetal foot length. Materials and methods This was a prospective, cross-sectional study conducted on 300 pregnant women between 18 and 39 weeks of gestation after obtaining their written informed consent. Our inclusion criteria were women with singleton pregnancies who were certain of their last menstrual periods; who had previous regular menstrual cycles; who had undergone a fi rst trimester dating scan; who had a normal anomaly scan; and with normal amniotic fl uid volume. Each patient underwent a detailed antenatal ultrasound study in which, in addition to routine fetal biometry, each fetal foot length was measured. In each fetus, the measurements of the two feet were averaged for analytical purpose. For each gestational age, the fetal foot length was calculated from the raw data and linear regression analysis was used to establish a relationship between sonographic gestational age and fetal foot length. The p value was also calculated to estimate the level of signifi cance. Results Our study demonstrated a strong statistically significant linear relationship between gestational age and fetal foot length during the second and third trimesters of gestation.

Imaging by Ultrasound (US) is an accurate and useful modality for the assessment of gestational age (GA), estimation fetal weight, and monitoring the fetal growth during pregnancy, is a routine part of prenatal care, and that can greatly impact obstetric management. Estimation of GA is important in obstetric care, making appropriate management decisions requires accurate appraisal of GA. Accurate GA estimation may assist obstetricians in appropriately counseling women who are at risk of a preterm delivery about likely neonatal outcomes, and it is essential in the evaluation of the fetal growth and detection of intrauterine growth restriction. There are many formulas are used to estimate fetal GA in the world, but it's not specify for Iraqi population and leading to some error in GA estimation results, so the objective of this study is to innovate GA estimation model for Iraqi people. This study was performed in the department of Obstetrics and Gynecology in Al- Yarmouk Teaching Hospital and AL- Alawiya Teaching Hospital in Baghdad, Iraq, during 2019 on 200 pregnant women of singleton and normal pregnancies, fetal GA (20-40) weeks (W). The obtained dataset (fetal biometry), were utilized to create GA estimation model in Iraq using IBM SPSS Version 23 software package (IBM^® Software). The statistical analysis of proposed GA model showed, the correlation (R) of model is 0.987 it is very high value and this is a good result to obtain the best regression model. as well as the Std error of Estimation was 0.61095 this is very small value and indicate the best result. The significant of model P=0.000 That means the model, as a whole, is a significant fit to the data (because P < 0.05). Keywords: Ultrasound, Fetal Biometry, Estimation Gestational Age, SPSS.

No Gold Standard

Small for gestational age (SGA) and fetal growth restriction (FGR) is difficult to define exactly. In this pregnancy condition, the fetus does not reach its biological growth potential as a consequence of impaired placental function, which may be because of a variety of factors. Fetuses with FGR are at risk for perinatal morbidity and mortality, and poor long-term health outcomes, such as impaired neurological and cognitive development, and cardiovascular and endocrine diseases in adulthood. At present no gold standard for the diagnosis of SGA/FGR exists. The first aim of this review is to: summarize areas of consensus and controversy between recently published national guidelines on small for gestational age or fetal growth restriction; highlight any recent evidence that should be incorporated into existing guidelines. Another aim to summary a number of interventions which are being developed or coming through to clinical trial in an attempt to improve fetal growth in placental insufficiency. Key words: fetal growth restriction (FGR), Small for gestational age (SGA)
