OBJECTIVE: To investigate the potential value of repeat measurements of uterine artery pulsatility index (UTPI), mean arterial pressure (MAP) and serum placental growth factor (PLGF) at 12, 22 and 32 weeks' gestation in the prediction of preeclampsia (PE) after 32 weeks. METHODS: The data were derived from prospective screening for adverse obstetric outcomes in women attending for their routine hospital visit at 11-13, 19-24 and / or 30-34 weeks' gestation in two maternity hospitals in England...

K Karl, T Esser, K S Heling, R Chaoui
OBJECTIVE: While complete agenesis of the corpus callosum (CC) is often suspected on fetal ultrasound due to the absence of the cavum septi pellucidi (CSP), the suspicion of a partial agenesis (pACC) is still a challenge since the CSP is almost always present in these conditions. Aim of the study was to measure the length and width of the CSP and to calculate the ratio of the length to width as CSP-Ratio in fetuses with pACC and to compare with values from normal fetuses. PATIENTS: In a case-control study the CSP was measured in the axial plane of the fetal head in 323 normal fetuses between 20 and 34 weeks' gestation and reference ranges in relation to the biparietal diameter (BPD) were constructed...

OBJECTIVES: The main objectives of the present study were to establish the existence of significant differences in the incidence of central nervous system (CNS) anomalies (including microcephaly), signs of congenital infection, or foetal loss between Zika virus (ZIKV)-infected and non-infected pregnant women in western French Guiana. METHODS: This prospective cohort study was conducted between January 1(st) and July 15(th) 2016. We evaluated the clinical and foetal ultrasound (US) examinations of 301 pregnant women with biological confirmation of ZIKV infection and 399 pregnant women who were negative for ZIKV infection...

LETTER
A Ludwin, I Ludwin, W P Martins
Ultrasound with various contrast agents is widely used over quarter of a century for tubal patency testing. A venous intravasation is well-known event, which may occur during X-ray hysterosalpingography using oil- or water-soluble contrasts. There are no reports described this event during ultrasound tubal patency testing. We recorded the venous intravasation in women during air/saline hysterosalpingo-contrast sonography, which caused an inconclusive result of left tube evaluation. Subsequent foam infusion suggested an occluded left tube without sings of intravasation...

OBJECTIVE: To investigate associations between periconceptional maternal dietary patterns and first trimester embryonic growth. METHODS: 228 women with singleton ongoing pregnancies were enrolled in a prospective periconceptional cohort study, comprising of 135 strictly dated spontaneous pregnancies and 93 pregnancies achieved after in vitro fertilization or intracytoplasmatic sperm injection (IVF/ICSI pregnancies). All women underwent longitudinal transvaginal three-dimensional ultrasound (3D-US) scans from 6(+0) up to 13(+0) weeks of gestation...

OBJECTIVE: The aim of this systematic review and meta-analyses was to comprehensively describe the normotensive pattern of cardiac remodelling during human singleton pregnancies and compared to that during hypertensive complicated pregnancies. METHODS: We performed a meta-analysis of the current literature on cardiac remodelling during normotensive and complicated pregnancies. Literature was retrieved from PubMed (NCBI) and Embase (Ovid) databases. Included studies needed to report a reference measurement (matched non-pregnant control group, pre-pregnancy, or post-partum) and measurements during a predetermined gestational interval...

OBJECTIVES: To introduce a new sonographic marker of intrathoracic liver herniation in fetuses with left congenital diaphragmatic hernia (CDH) METHODS: In a consecutive series of fetuses with isolated CDH an ultrasound volume of the fetal abdomen was acquired. On this the offline calculation of the angle formed by the midline of the abdomen (joining the center of the vertebral body to the abdominal insertion of the umbilical cord) and a second line joining the center of the vertebral body to the intra-abdominal convexity of the umbilical vein was carried out (Umbilical Vein Deviation Angle or UVDA)...

OBJECTIVE: The aim of this study was to investigate whether presence of levator ani muscle (LAM) avulsion was associated with expulsion of vaginal pessary for women with pelvic organ prolapse (POP). METHODS: This prospective observational study recruited consecutive women with symptomatic POP. Vaginal pessary was offered and offline analysis of the 3D/4D transperineal ultrasound volume data of women was performed. Volume acquisition had been performed before pessary insertion...

OBJECTIVE: A growing body of evidence suggests that the surgical technique for uterine closure influences uterine scar healing, but there is still no consensus about optimal uterine closure during cesarean delivery (CD). The aim of this systematic review and meta-analysis was to compare the effect of single- versus double-layer closure on the risk of uterine scar defect. METHODS: MEDLINE, Scopus, http://ClinicalTrials.gov, the PROSPERO International Prospective Register of Systematic Reviews, EMBASE and the Cochrane Central Register of Controlled Trials were searched from inception of each database until May 2016...

OBJECTIVE: To examine the diagnostic accuracy of a previously developed model for prediction of preeclampsia (PE) by a combination of maternal factors and biomarkers at 11-13 weeks' gestation. METHODS: This was a prospective first-trimester multicenter study of screening for PE in 8,775 singleton pregnancies. A previously published algorithm was used for the calculation of patient-specific risk of PE in each patient. The detection rates (DR) and false positive rates (FPR) for delivery with PE at <32, <37 and ≥37 weeks were estimated and compared to those in the dataset used for development of the algorithm...

We report the first series of five cases of prenatal diagnosis of pericallosal curvilinear lipoma (CL) and underline limitations and pitfalls in identifying a specific prenatal imaging pattern using ultrasound and MRI. On ultrasound, the main referring feature was a short corpus callosum in all cases. This subtle callosal dysgenesis was associated with a band of hyperechogenicity surrounding the corpus callosum, which can mimic the pericallosal sulcus, and increased in size over the third trimester in three out of four cases in which sonographic follow-up was obtained...

OBJECTIVES: To assess endothelial function and arterial stiffness in women with a previous pregnancy complicated by haemolysis, elevated liver enzymes, and low platelet count (HELLP) syndrome, and compare them with women with a previous preeclampsia (PE) without HELLP and controls with uncomplicated pregnancies. METHODS: Women who have had a singleton pregnancy complicated by PE with (n = 49) or without (n = 60) HELLP syndrome and controls (n = 60) underwent peripheral arterial tonometry (EndoPAT method) and pulse wave velocity (PWV) assessment at 6 months-4 years after delivery...

INTRODUCTION: In recent years, a large number of studies have been published on the clinical relevance of pelvic floor three-dimensional (3D) transperineal ultrasound. Several studies compare ultrasonography to other imaging modalities or clinical examination. The quality of reporting these studies is not known.

OBJECTIVE: Cervical length screening by transvaginal ultrasound has been shown to be a good predictive test for spontaneous preterm birth (PTB) in symptomatic singleton pregnancies with threatened preterm labor (PTL). The aim of this Cochrane review and meta-analysis of individual participant data was to evaluate the effect of using knowledge of transvaginal ultrasound cervical length (TVU CL) in preventing PTB in singleton pregnancies presenting with threatened PTL. METHODS: We searched the Cochrane Pregnancy and Childbirth Group's Trials Register and the Cochrane Complementary Medicine Field's Trials Register (May 2016) and reference lists of retrieved studies...

In contrast to single nuchal cords, which occur in 15.8% to 30% of singleton fetuses at term and have not been unequivocally associated with significant adverse perinatal outcome, true knots of the umbilical cord occur in 0.04 to 3% of deliveries, and have been associated with perinatal morbidity in 11% of cases, and a 4-10 fold increase in stillbirth. Following the relatively high incidence of single nuchal cords at term and the relatively infrequent observation of a true knot of the umbilical cord (often noted incidentally at delivery), guidelines have not yet been provided for the management of pregnancies complicated by prenatal diagnosis of nuchal or true knots of the umbilical cord...
