OBJECTIVE: Most ultrasound estimated fetal weight (EFW) formulas incorporate abdominal circumference, which may overstimate growth restriction in fetal gastroschisis. The aim of this study was to determine the optimal ultrasound formula for prediction of birthweight and fetal growth restriction (FGR) in gastroschisis. STUDY DESIGN: We conducted a retrospective cohort analysis ...

Fetal bowel calcifications were observed at 24 weeks of gestation in a male fetus, suggesting an anorectal malformation (ARM) with rectourethral fistula. At birth, the newborn presented with complex ARM including anal atresia, rectourethral fistula, and esophageal atresia. The prenatal sonographic visualization of calcifications within distended bowel should raise the ...

Foetal growth restriction is an important contributor to perinatal mortality, being responsible for up to 50% of stillbirths. Optimal prevention and accurate detection enabling timely intervention remain elusive, particularly in presumed low-risk pregnancy. Third trimester ultrasound seems a logical solution, but systematic review of evidence from randomised trials has shown ...

Miscarriage is the most common serious pregnancy complication affecting approximately 30% of biochemical pregnancies and 11-20% of clinically recognised pregnancies. The diagnosis of miscarriage is made most commonly by trans-vaginal ultrasound (TVS) assessment. Evidence-based criteria should be employed for the diagnosis of delayed and incomplete miscarriage. Complete miscarriage should not ...
