BACKGROUND: Early fetal echocardiography (FE), performed at 12 to 16 weeks' gestational age (GA), can be used to screen for fetal heart disease akin to that routinely performed in the second trimester. The efficacy of FE at earlier GAs has not been as well explored, particularly with recent advances in ultrasound technology. The aim of this study was to evaluate the efficacy of early FE in assessing fetal heart structure, and the added benefit of color Doppler (CD), from as early as 6 weeks through to 13(+6) weeks' GA...

OBJECTIVE: To investigate prenatal diagnosis and postnatal outcome of fetuses with crossed ectopic kidney METHODS: Cases referred for an empty renal fossa and diagnosed with crossed ectopic kidney confirmed postnatally were analyzed retrospectively over a period of 10 years. Prenatal diagnosis was established following the detection of one kidney in a normal position, and a second ipsilateral kidney fed by abnormal blood vessels on Doppler flow. RESULTS: Between 2005 and 2015, 185 fetuses were referred for an empty renal fossa...

Foetal premature atrial contractions (PACs) are the most commonly encountered and also the most benign foetal arrhythmia. A retrospective cohort study was conducted with the objective to assess whether the presence of foetal breathing was associated with the presence of foetal PACs. A further objective was to evaluate whether this association would affect neonatal outcomes at a high volume referral centre. The diagnosis of PACs was based on the observation of a premature atrial contraction followed by a ventricular contraction on ultrasound myocardial M-mode...

The placenta plays a crucial role throughout pregnancy, and its importance may be overlooked during routine antenatal imaging evaluation. Detailed systematic assessment of the placenta at ultrasonography (US), the standard imaging examination during pregnancy, is important. Familiarity with the normal and abnormal imaging appearance of the placenta along with the multimodality and methodical approach for evaluation of its related abnormalities is necessary, so that radiologists can alert clinicians regarding appropriate prompt management decisions...

Tubal choriocarcinoma is uncommon, and its magnetic resonance imaging characteristics have not yet been reported. In this report, a 39-year-old woman presented with irregular painless vaginal bleeding and a palpable left lower abdominal lump for 2 months following 6 weeks' amenorrhea and positive urine pregnancy test. Her serum β-human chorionic gonadotropin value was significantly increased. Ultrasound revealed a left adnexal mass, which showed no blood flow signal on Color doppler flow imaging. A further MR examination showed a well-defined cystic-solid mass with cystic component accounting for a large proportion in the left lower abdomen...

We performed a dual-gate Doppler examination for a twin reversed arterial perfusion (TRAP) sequence in a monochorionic-triamniotic triplet pregnancy at 16 weeks of gestation and were able to identify the pump twin by arterial pulse rate synchronicity. We performed radiofrequency ablation to coagulate blood flow in the acardius at 16 weeks of gestation without any postoperative complication. At 29 weeks of gestation, we performed a cesarean section due to preterm rupture of the membranes and the patient delivered 1167/1237-g female neonates and a macerated acardius...

Umbilical cord entanglement is the leading cause of fetal mortality in monoamniotic twin pregnancies and a pseudo monoamniotic environment. Published methods for detecting this complication include color Doppler and pulsed Doppler sonography; however, no method provides an absolute diagnosis. In this case, we report the diagnosis of umbilical cord entanglement using dual-gate Doppler imaging. A 35-year-old woman was referred to our hospital at 28 weeks of gestation for prenatal management because of diagnosis of a monochorionic diamniotic twin pregnancy with spontaneous septostomy of the dividing membranes...

Postpartum hemorrhage (PPH), a leading cause of maternal mortality, can occur within 24 h of delivery (primary PPH), or during the period from 24 h after delivery to Week 6 of puerperium (secondary PPH). It requires health professionals to be alert to the symptoms to ensure prompt diagnosis and treatment, especially in the case of rupture of a uterine artery pseudoaneurysm (UAP) due to its life-threatening consequence (Baba et al., 2014). Most of the published case reports or case serials describe UAP as a possible cause of delayed PPH after traumatic procedures during delivery or pregnancy termination, including cesarean section (CS), manual removal of the placenta, or dilation and curettage (D&C) (Wald, 2003)...

This prospective cohort study aimed to evaluate the role of premature placental calcification in adverse pregnancy outcomes and identify its associated potential risk factors. We consecutively enrolled 293 women who presented to three academic medical centres from September 2011 to March 2013. Participants underwent transabdominal sonographies between 28-36 weeks of gestation in an attempt to determine placental maturity. We compared maternal and foetal outcomes between two groups of women, those with grade III placenta (n = 69) and those without grade III placenta (n = 224)...

REVIEW
Jessica M Page, Robert M Silver
Stillbirth is one of the most distressing complications of pregnancy and still occurs far too frequently. The rate of stillbirth has been decreasing worldwide but room for improvement remains even in high-income countries. Risk factors for stillbirth have been identified in an effort to detect those women at increased risk. However, risk factors are non-specific and do not identify most stillbirths. Strategies employed to screen the general population such as assessment of fetal activity, fetal growth screening and biomarkers have also been used to identify increased risk for stillbirth...

BACKGROUND: Chronic hypertension in adults causes arterial lengthening in major arteries, but the effects of early fetal hypertension on the twin-twin transfusion syndrome (TTTS) recipient's vascular architecture remains unknown. OBJECTIVES: We hypothesize that arterial cord redundancy is related to recipient hypertension and subsequent heart failure. Our objectives were: 1) to establish a 3D color Doppler ultrasound method of measuring umbilical arterial (UA) length relative to its corresponding venous segment in the Umbilical cord using AV-angle, 2) to compare recipient AV-angle to gestational age-matched controls, and 3) to test the association of AV-angle with recipient heart failure...

INTRODUCTION: Soluble fms-like tyrosine kinase 1 (sFLT-1) is an anti-angiogenic factor implicated in the pathogenesis of preterm preeclampsia. We evaluated sFLT-1 expression and placental pathology in pregnancies complicated by small for gestational age (SGA) infants (<10th percentile), without evidence of preeclampsia. METHODS: Clinical and histologic data were compared between groups with high or low sFLT-1 expression determined by immunohistochemistry on archived placentas...
