The aim was to determine the predictive role of combined screening for late-onset gestational hypertension by fetal ultrasound measurements, third trimester uterine arteries (UtAs) Doppler imaging, and maternal history. This prospective study on singleton pregnancies was conducted at the tertiary center of Maternal and Fetal Medicine of the University of Padua during the period between January 2012 and December 2014. Ultrasound examination (fetal biometry, fetal wellbeing, maternal Doppler study, fetal abdominal aorta intima-media thickness [aIMT], and fetal kidney volumes), clinical data (mother age, prepregnancy body mass index [BMI], and parity), and pregnancy outcomes were collected...

BACKGROUND: Twin gestations are at significantly higher risk of fetal growth restriction in comparison with singletons. Using fetal biometric charts customized for obstetrical and parental characteristics may facilitate accurate assessment of fetal growth. OBJECTIVE(S): To construct reference charts for gestation of fetal biometric parameters stratified by chorionicity and customized for obstetrical and parental characteristics. STUDY DESIGN: Fetal biometric measurements obtained from serial ultrasound examinations in uncomplicated twin pregnancies delivering after 36 weeks of gestation were collected by 19 Italian fetal medicine units under the auspices of the Società Italiana di Ecografia Ostetrica e Ginecologica...

We describe a rare case of heterotopic pregnancy following in vitro fertilization with transferring of two embryos in a 39-year-old woman with previous bilateral salpingectomy. An ultrasound examination was performed on the day before admission showing a vital intrauterine pregnancy and no ectopic pregnancy. The woman was admitted with a ruptured cornual pregnancy at ten weeks of gestation. Laparotomy was performed on vital indication with excision of the ruptured haemorrhagic cornual pregnancy. The intrauterine pregnancy continued uneventfully with obstetric and fetal medicine specialist monitoring...

BACKGROUND: In-utero MRI (iuMRI) has shown promise as an adjunct to ultrasound but the comparative diagnostic performance has been poorly defined. We aimed to assess whether the diagnostic accuracy and confidence of the prenatal diagnosis of fetal brain abnormalities is improved with iuMRI and assess the clinical impact and patient acceptability of iuMRI. METHODS: We did a multicentre, prospective, cohort study in the UK, at 16 fetal medicine centres, of pregnant women aged 16 years or older whose fetus had a brain abnormality detected by ultrasound at a gestational age of 18 weeks or more, had no contraindications to iuMRI, and consented to enter the study...

BACKGROUND: Gastroschisis is the most common major congenital anomaly managed by paediatric surgeons. The significance of certain associated antenatal ultrasound features in determining fetal outcome is under discussion. AIM: The study aims to define if associated antenatal ultrasound features of gastroschisis are useful prognostic markers for fetal outcome. By establishing the significance of features, including extra- and intra-abdominal bowel dilatation, stomach herniation, stomach dilatation, bowel matting, growth restriction, abnormal umbilical artery (UA) Doppler ultrasounds, and abnormal amniotic fluid volume, it is hoped clinicians will have enhanced ability to counsel parents about the likely outcomes for their infant...

BACKGROUND: Due to the recent outbreak of Zika virus, there has been a newfound interest in fetal and neonatal microcephaly. In 1984, Chervenak et al. proposed criteria for the prenatal ultrasound diagnosis of microcephaly as ≤3 standard deviations (SD) from the mean. Despite improvements in medicine these criteria have not been reevaluated in 30 years. OBJECTIVE: To examine how the original 1984 Chervenak et al. criteria for the diagnosis of fetal microcephaly apply to a current population utilizing modern ultrasound equipment and techniques...

INTRODUCTION: Brain natriuretic peptide (BNP) is synthesized by human fetal membranes, both the amnion and chorion. This locally produced BNP inhibits the contraction of the human myometrium, contributing to the maintenance of myometrial quiescence during pregnancy. Reference values for NT-proBNP concentrations in amniotic fluid at different gestational ages have not been completely defined. We aimed to investigate the range of fetal NT-proBNP values in amniotic fluid in normal pregnancy between 17 and 41weeks of gestation...
