OBJECTIVE: To assess the frequency of atypical chromosomal and submicroscopic anomalies [both undetectable using standard cell-free DNA (cfDNA) testing], as well as fetal structural abnormalities observed at the first-trimester scan, in fetuses with an increased nuchal translucency (NT). METHODS: From January 2013 to December 2017, 226 fetuses with an NT ≥ 99th centile at 11-13 weeks' gestation underwent genetic testing by means of quantitative fluorescence polymerase chain reaction (QF-PCR) and chromosomal microarray analysis (CMA) mainly in chorionic villi, in a clinical setting in which more than 95% of pregnant women receive first-trimester combined screening...

We present images of a fetus at 34 weeks of gestation for which an evaluation of the tongue was performed to visualize the blood vessels using HD-FlowTM and SlowflowHDTM GE® modalities, a 2-9 curvilinear probe and an RM6C volumetric probe. A cross-sectional image of the fetal head with the face upturned was obtained; the evaluation plane was located in the middle of the oral cavity with a clear image of the tongue. Figure 1 shows the deep lingual arteries in each side of the tongue with their lateral branches and their final trajectories orientated toward the medial region of the tongue...

Pseudoamniotic band formation is a rare complication of invasive in-utero interventions and occurs in 1.8-3.3% of cases of fetoscopic laser photocoagulation for twin to twin transfusion syndrome (TTTS). We report a case of successful release of pseudoamniotic bands that followed laser photocoagulation for twin to twin transfusion syndrome using a partial carbon dioxide uterine environment.

Preterm birth is a major health problem with complex and diverse etiology. Cervical pessary has been tried as a simple, non-invasive alternative that might replace cerclage due to the fact that it has fewer potential complications. Ultrasound has been linked to preterm birth guidelines using some technological improvements. The aim here is to show a 3D ultrasound view of cervical pessary. This article is protected by copyright.

BACKGROUND: Selective fetal growth restriction occurs in monochorionic twin pregnancies where unequal placental sharing leads to restriction in the growth of just one twin. The management options include laser separation of the fetal circulations, selective reduction or expectant management, but the best treatment is not yet known. New trials in this area are urgently needed, but in this rare and complex group maximising the relevance and utility of clinical research design and outputs is paramount...

OBJECTIVES: The Management Of Myelomeningocele Study (MOMS) trial demonstrated the safety and efficacy of open fetal surgery for spina bifida (SB). Recently developed alternative techniques may reduce maternal risks yet should do without compromising on fetal neuroprotective effects. We aimed to assess the learning curve of different fetal SB closure techniques. METHODS: We searched Medline, Web of Science, Embase, Scopus and Cochrane databases and the grey literature to identify relevant articles without language restriction from January 1980 until October 2018...

OBJECTIVE: The anal sphincter is commonly evaluated with endo-anal ultrasound (EAU). Recently, trans-labial ultrasound (TLUS) has been proposed for sphincter imaging, with moderate to good correlation between methods. An endo-sonographic defect is defined as a defect of ≥30o in 2/3 slices. This is equivalent to 4/6 slices on tomographic ultrasound (TUI), a definition which has been validated. This study was designed to validate defect angle for the definition of 'significant anal sphincter trauma'...

OBJECTIVES: To determine the feasibility and tissue yield from a perinatal incision-less ultrasound guided biopsy procedure, in the context of a 'minimally invasive autopsy' (MIA). METHODS: Perinatal cases that consented for MIA underwent post-mortem MRI and 'INcisionless TArgeted Core Tissue' (INTACT) biopsy procedure, defined as organ needle biopsy via the umbilical cord performed under ultrasound guidance. Three cores of tissue were obtained from 7 target organs for each case (both lungs, both kidneys, heart, spleen and liver)...

BACKGROUND: Justification of prenatal screening for small for gestational age (SGA) fetuses near term is based on first, evidence that such fetuses / neonates are at increased risk of stillbirth and adverse perinatal outcome, and second, the expectation that these risks can be reduced by medical interventions, such as early delivery. However, there are no randomized studies demonstrating that routine screening for SGA fetuses and appropriate interventions in the high risk group can reduce adverse perinatal outcome...

Arteriovenous shunts in the fetal liver are very rare vascular malformations especially when multiple, or related to aorta and umbilical vein (UV) (1,2). To the best of our knowledge, only one prenatal report involved abdominal aorta, as an aorta-porto-umbilical vein fistula (3). We communicate a case with aorta-UV communications emerging from celiac and superior mesenteric sites, and describe its features and associations. This article is protected by copyright.

Tetralogy of Fallot with absent pulmonary valve (TOF/APV) is a rare congenital heart disease, which can be associated with abnormalities of the pulmonary veins and variations in the aortic arch (e.g. right aortic arch). We describe the case of a fetus with an unusual subclavian artery that arose from the lower thoracic descending aorta, which was misinterpreted as an arterio-venous fistula. This vessel connected with a relatively short and dilated ductus arteriosus (DA). There were also partial abnormal pulmonary vein connections (PAPVC) diagnosed in 2 pulmonary veins postnatally...

OBJECTIVES: Direct chromosome preparations of chorionic villus samples (CVS) and cell-free (cf) DNA testing both involve analysis of the trophoblastic cell lineage. We compared the spectrum of rare autosomal trisomies (RATs) detected by these two approaches and assessed the available information on their clinical significance. METHODS: Data from 10 reports on genome-wide cfDNA testing were pooled to determine which chromosomes were most frequently involved and pregnancy outcome information was reviewed...

OBJECTIVE: To determine the intra- and interrater reliability and agreement for ultrasound measures of pelvic floor contraction and to study any correlation between ultrasound and vaginal palpation for measurement of pelvic floor muscle contraction. We also aimed to develop an ultrasound scale for assessment of pelvic floor contraction. METHODS: We examined pelvic floor muscle contraction in 195 women scheduled for stress urinary incontinence surgery (n=65), prolapse surgery (n=65), and primigravida (n=65) with vaginal palpation (Modified Oxford Scale (MOS)) and two- and three-dimensional (2D/3D) transperineal ultrasound...

OBJECTIVES: To assess the accuracy of the ultrasound examination in the prediction of lymph node status (LN) in vulvar cancer patients. METHODS: This is a single institution retrospective observational study, conducted between December 2010 to January 2016. All women with a histological diagnosis of vulvar cancer triaged to inguinal surgery within 30 days from an ultrasound evaluation were included in the study. For each groin, 15 morphological and dimensional sonographic parameters of suspicion for lymph node involvement were examined...

OBJECTIVE: To evaluate the level of agreement in the prenatal magnetic resonance imaging (MRI) assessment of the severity of placenta accreta spectrum (PAS) disorders in centers with high expertise in their diagnosis and management. METHODS: The MRI scans of women at risk of PAS were retrieved from the hospital electronic database and assessed by four different experts who were blinded to the final diagnosis. Each examiner was asked to judge the MRI scans according to the presence, depth and topography of placental invasion...

A 30-year primigravida presented at 35 weeks and 5 days gestation with persistent breech for external cephalic version (ECV). Systematic ultrasound examination showed a normally grown fetus with extreme looping of nuchal cord (NC) around the fetal neck with head hyperextension (Fig. a and b). On 3D ultrasound there was an impression of "tribal neck rings" (Fig. c). No free umbilical cord was seen in the amniotic fluid. ECV was not performed. At 37 weeks gestation the patient had reduced fetal movements...
