OBJECTIVE: Fetal endoscopic tracheal occlusion (FETO) is associated with increased perinatal survival and reduced need for Extracorporeal Membrane Oxygenation (ECMO) among fetuses with severe congenital diaphragmatic hernia (CDH). This study evaluates the impact of FETO on the resolution of pulmonary hypertension (PH) in fetuses with isolated CDH. METHODS: All fetuses evaluated for CDH between January 2004 and July 2017 at a single institution were included. CDH cases were retrospectively reclassified by prenatal MRI severity indices, (observed to expected total lung volume and percent liver herniation) into mild, moderate, and severe groups...

OBJECTIVES: Less invasive autopsy techniques have good acceptability to parents, but the published sampling adequacy of needle biopsy studies is generally poor. Minimally Invasive Autopsy with Laparoscopic assisted sampling (MinImAL) has the potential to increase the diagnostic yield of less invasive autopsy by improving the quality and quantity of tissue samples obtained, whilst concomitantly permitting visualisation, extraction and examination of internal organs through a small incision...

Placenta accreta spectrum (PAS) is a complex obstetric complication associated with high maternal morbidity. Several prenatal ultrasound signs of PAS were reported: mainly the disappearance of the normal uteroplacental interface (clear zone), extreme thinning of the underlying myometrium, and vascular changes within the placenta (lacunae) and placental bed (hypervascularity).1, 2 The ability of the ultrasound to detect PAS is dependent upon several factors, such as operator experience, gestational age at assessment, number of abnormal ultrasound findings, and actual degree of placental invasion...

INTRODUCTION: Aberrant right subclavian artery (ARSA) is a relatively common sonographic finding. Several studies have reported a significant association between ARSA and Down syndrome, as well as with 22q11 microdeletion. The objective of our study was to analyze the yield of chromosomal microarray analysis in a large cohort of pregnancies with ARSA as an isolated as well as non-isolated sonographic anomaly. METHODS: Data from all pregnancies referred for invasive testing and chromosomal microarray analysis (CMA) due to fetal ARSA between the years 2013-2017 were retrospectively obtained from Israeli Ministry of Health's computerized database...

OBJECTIVES: Both levator ani trauma and hiatal overdistension are factors in the etiology of female pelvic organ prolapse (POP). However, the role of the configuration or shape of the levator hiatus has not been examined to date. The aim of this study was to investigate the association between configuration of the levator ani hiatus and pelvic organ prolapse. METHODS: This was a retrospective study on 547 women who had attended a tertiary urogynecologycal center for symptoms of pelvic floor and lower urinary tract dysfunction between October 2014 and August 2016...

Left atrial isomerism (LAI) is a rare type of heterotaxy syndrome1 . The most common anomalies of the fetuses with LAI are the absence of the hepatic segment of the inferior vena cava (IVC), the interrupted suprarenal IVC segment with enlarged azygos or hemiazygos vein continuation, and the azygos vein passing posterior of the aorta and running up to join the superior vena cava (SVC)2 .

OBJECTIVES: To report the rate of additional anomalies detected exclusively on prenatal MRI in fetuses affected by isolated mild or moderate ventriculomegaly (VM) according to the type of ultrasound protocol adopted (dedicated neurosonography vs standard assessment of fetal brain) and to explore whether the diagnostic performance of fetal MRI in detecting such anomalies is affected by gestational age at scan and laterality of ventricular dilatation. METHODS: The primary aim was to report the rate of additional anomalies detected exclusively on prenatal MRI in fetuses affected by isolated mild and moderate VM (ventricular dilatation between 10-15 mm) undergoing compared to those not undergoing dedicated neurosonography, defined as a detail assessment of fetal brain according to the International Society of Ultrasound in Obstetrics and Gynecology guidelines...
