Article Synopsis
- The study aimed to distinguish between placenta accreta spectrum (PAS) and uterine-scar dehiscence using standardized ultrasound techniques, which is often difficult even for experts.
- A retrospective cohort study was conducted with women who had previous Cesarean deliveries and current pregnancies with low-lying placenta conditions, analyzing various ultrasound markers to classify cases of PAS and non-PAS.
- Out of 150 cases reviewed, 144 were included in the analysis, resulting in 89 PAS cases, 23 uterine-scar dehiscence cases, and 32 cases with uncomplicated low-lying placenta or placenta previa.
The impact of late pregnancy dating on the detection of fetal growth restriction at term.

Introduction: The inaccuracy of late pregnancy dating is often discussed, and the impact on diagnosis of fetal growth restriction is a concern. However, the magnitude and direction of this effect has not previously been demonstrated. In this study, we aimed to investigate the effect of late pregnancy dating by head circumference on the detection of late onset growth restriction, compared to first trimester crown-rump length dating.

Introduction: Birth before arrival is associated with maternal morbidity and neonatal morbidity and mortality. Yet, timely risk stratification remains challenging. Our objective was to identify risk factors for birth before arrival which may be determined at the first antenatal appointment.

Methods: This is a 5-year retrospective cohort study using routinely collected data. Inclusion criteria were singleton, non-anomalous pregnancies having a growth scan with umbilical artery Doppler velocimetry between 28 + 0 and 33 + 6 weeks' gestation.
Detection of small- and large-for-gestational age using different combinations of prenatal and postnatal charts.
Ultrasound Obstet Gynecol
September 2022
Objective: To determine the extent to which the detection rate of small-for-gestational age (SGA) and large-for-gestational age (LGA) at birth is influenced by the use of different combinations of estimated-fetal-weight (EFW) and birth-weight (BW) charts.
Methods: This was a cohort study of all pregnant women with a singleton term birth receiving care in a university hospital during a 3-year period. All participants underwent a universal 36-week ultrasound scan for EFW measurement and had BW recorded at delivery.
