OBJECTIVE: Poor fetal and perinatal outcomes in fetuses associated with umbilical artery thrombosis (UAT), such as severe intrauterine growth restriction (IUGR) and intrauterine asphyxia have been reported by some case series. Its hemodynamic impact remains unclear. The aim of this study was to evaluate the hemodynamic changes and perinatal outcome in UAT fetuses with a relatively large sample. METHODS: We included singleton fetuses diagnosed with UAT and with at least one available Doppler evaluation before the end of pregnancy in our center from 2016 to 2023...

BACKGROUND: Significant disparities in sonographic education exist in Obstetrics and Gynecology programs in the United States. To address the lack of standardization in ultrasound teaching, the American Institute of Ultrasound in Medicine (AIUM) assembled a multi-society task force in 2018 which resulted in the publication of a Consensus Report outlining a standardized ultrasound curriculum and competency assessment. OBJECTIVES: The primary objective of the study was to implement the AUIM standardized curriculum within an Obstetrics and Gynecology residency program at a tertiary medical center, and report on the early implementation experience...

OBJECTIVE: Fetal growth assessment by ultrasound aims to identify small babies that are at higher risk of perinatal morbidity and mortality. The current study explores if the association between suboptimal fetal growth and adverse perinatal outcome varies with different definitions of fetal growth restriction and weight charts/standards. METHODS: This was a retrospective cohort study of 17261 singleton non-anomalous pregnancies from 24+0 weeks' gestation at a tertiary referral hospital...

Regarding the hypertensive disorders of pregnancy, pre-eclampsia (PE) remains one of the leading causes of severe and life-threatening maternal and fetal complications. Screening of early-onset PE (<34 weeks of pregnancy), as well as late-onset PE (≥34 weeks), shows poor performance if based solely on clinical features. In recent years, biochemical markers from maternal blood-the pro-angiogenic protein placental growth factor (PlGF) and the antiangiogenic protein soluble FMS-like tyrosine kinase 1 (sFlt-1)-and Doppler velocimetry indices-primarily the mean uterine pulsatility index (PI), but also the uterine resistivity index (RI), the uterine systolic/diastolic ratio (S/D), uterine and umbilical peak systolic velocity (PSV), end-diastolic velocity (EDV), and uterine notching-have all shown improved screening performance...

BACKGROUND: Cardiac heart defects affect nearly 6-12 per 1000 live births in the general population and are more frequent than common trisomies. AIM: To assess the efficacy and technical limitations of first-trimester fetal heart evaluation in the 11-14th -weeks' scan and comparison with the second-trimester anatomical exam by ultrasound. MATERIAL AND METHOD: Between April 2015 and July 2020, medical records and ultrasound data of 3295 pregnancies who underwent first-trimester fetal anatomy exams by ultrasound were reviewed retrospectively...

PURPOSE: To analyze the learning curves of ultrasound novices in fetal echocardiography during structured simulation-based ultrasound training (SIM-UT) including a virtual, randomly moving fetus. METHODS: 11 medical students with minimal (< 10 h) prior obstetric ultrasound experience underwent 12 h of structured fetal echocardiography SIM-UT in individual hands-on sessions during a 6-week training program. Their learning progress was assessed with standardized tests after 2, 4, and 6 weeks of SIM-UT...

Twin gestations are associated with increased risk of pregnancy complications. However, high-quality evidence regarding the management of twin pregnancies is limited, often resulting in inconsistencies in the recommendations of various national and international professional societies. In addition, some recommendations related to the management of twin gestations are often missing from the clinical guidelines dedicated to twin pregnancies and are instead included in the practice guidelines on specific pregnancy complications (eg, preterm birth) of the same professional society...

OBJECTIVES: Congenital heart defects (CHDs) are the most common birth defects. Recently, artificial intelligence (AI) was used to assist in CHD diagnosis. No comparison has been made among the various types of algorithms that can assist in the prenatal diagnosis. METHODS: Normal and abnormal fetal ultrasound heart images, including five standard views, were collected according to the International Society of Ultrasound in Obstetrics and Gynecology (ISUOG) Practice guidelines...

OBJECTIVES: To analyze the feasibility of structured ultrasound simulation training (SIM-UT) in teaching second-trimester ultrasound screening using a high-end simulator with a randomly moving fetus. METHODS: This was a prospective, controlled trial. A trial group of 11 medical students with minimal obstetric ultrasound experience underwent 12 hours of structured SIM-UT in individual hands-on sessions within 6 weeks. Learning progress was assessed with standardized tests...

OBJECTIVE: Compare the neonatal outcomes of two protocols of diagnosis and surveillance of pregnancies complicated by early-onset FGR in a tertiary hospital. METHODS: This is a retrospective cohort study of pregnant women diagnosed with early-onset FGR between 2017 and 2020. We compared the obstetric and perinatal outcomes between two different management protocols (before and after 2019). RESULTS: Seventy-two cases of early-onset FGR were diagnosed in the forementioned period: 45 (62...

OBJECTIVES: To develop and validate an index predictive of adverse perinatal outcome (APO) in pregnancies meeting the consensus-based criteria for fetal growth restriction (FGR) endorsed by the International Society of Ultrasound in Obstetrics and Gynecology (ISUOG). METHODS: This was a retrospective analysis of consecutive singleton non-anomalous gestations meeting the ISUOG-endorsed criteria for FGR at a single tertiary care center from November 2010 to August 2020...

Objectives: To evaluate the competency of medical sonographer students who have completed training to estimate the gestational age (GA) and perform fetal biometric measurements compared to obstetricians. Methods: We conducted a cross-sectional observational study at the end of the medical sonographer students' practice sessions. In total, 80 midtrimester (18-28 weeks) pregnant women were recruited, and an ultrasound was performed according to the International Society of Sonography in Obstetrics and Gynecology (ISUOG) guideline...

OBJECTIVE: To assess in a group of ultrasound operators (US) of various levels of experience the predictive value of systematic quality scoring to assess estimated fetal weight (EFW) validity METHODS: Screenshots, sonographer experience, and neonates' birth weight (BW) were collected for 131 US examinations in the 7 days before birth. The difference (EFW error) between projected birth weight [EFW + (30 grams × interval in days to birth)] and actual BW was then assessed (absolute value)...

OBJECTIVE: To investigate the role of fetal brain magnetic resonance imaging (MRI) in detecting associated anomalies in fetuses with congenital cytomegalovirus (CMV) infection and normal neurosonography. METHODS: This was a multicenter, retrospective cohort study of patients examined between 2012 and 2021 in 11 referral fetal medicine centers in Italy. Inclusion criteria were fetuses with congenital CMV infection diagnosed by polymerase chain reaction analysis of amniotic fluid, pregnancies that underwent detailed multiplanar ultrasound assessment of the fetal brain as recommended by the International Society of Ultrasound in Obstetrics and Gynecology, maternal age ≥ 18 years, normal fetal karyotype and MRI performed within 3 weeks after the last ultrasound examination...

INTRODUCTION: Several congenital abnormalities present late in pregnancy necessitating invasive testing to rule out genetic/infectious causes at late gestation. Not many studies have described the indications/safety of a late gestation amniocentesis. METHODS: All records of amniocentesis performed beyond 24 weeks were reviewed and evaluated for indications, positive yield and complications. RESULTS: About 187 women had an amniocentesis after 24 weeks for various indications with CNS abnormalities being the commonest...
