Persistent ductus venosus as a cause of cholestatic jaundice is very rare. Treatment varies, but is usually reserved for infants in whom complications develop. We report a 5-week-old female infant with cholestatic jaundice caused by a patent ductus venosus and subsequent successful treatment via a transcatheter occlusion using a vascular plug device.

OBJECTIVES: To investigate whether the addition of maternal serum placental growth factor (PlGF) measured at 11-13 weeks' gestation improves the performance of screening for stillbirths that is achieved by a combination of maternal factors and first-trimester biomarkers such as maternal serum pregnancy-associated plasma protein-A (PAPP-A), fetal ductus venosus pulsatility index for veins (DV-PIV) and uterine artery pulsatility index (UtA-PI) and to evaluate the performance of screening with this model for all stillbirths and those due to impaired placentation and unexplained causes...

OBJECTIVE: In the TRUFFLE study on outcome of early fetal growth restriction women were allocated to three timing of delivery plans according to antenatal monitoring strategies based on reduced computerized cardiotocographic heart rate short term variation (c-CTG STV) , early Ductus Venosus (DV p95) or late DV (DV noA) changes. However, many infants were per protocol delivered because of 'safety net' criteria, or for maternal indications, or 'other fetal indications' or after 32 weeks of gestation when the protocol was not applied anymore...

OBJECTIVES: To determine the prognostic value of fetal Doppler and echocardiographic parameters for neonatal survival up to 30 days after laser coagulation in monochorionic pregnancies complicated by twin-twin transfusion syndrome (TTTS). METHODS: Fetal echocardiography and outcome data of consecutive cases of TTTS treated by laser were retrospectively reviewed. Hemodynamic and cardiac function parameters were collected before and after laser. RESULTS: Between February 2006 and January 2015, 106 fetoscopic laser were performed...

BACKGROUND: There are sex differences in the risk of development of cardiovascular disease (CVD). According to the developmental origins of health and disease paradigm (DOHaD), CVD originates in fetal life. This study examines fetal sex differences in cardiovascular development in utero. METHODS: In 1028 pregnant women, we assessed fetal circulation using pulsed wave Doppler examinations between 28 and 34 weeks gestation. To test associations between fetal sex and fetal circulation measurements, linear regression models were used adjusting for fetal size, gestational age, and fetal heart rate...

Antenatal diagnosis of congenital heart disease (CHD) is still low even though screening was first introduced over 25 years ago. The purpose of our study was to determine the efficacy of a second-trimester prenatal ultrasonographic method of screening for CHD.From September 2012 to September 2013, the length and width of the fetal ductus venosus were measured sonographically in 1006 singleton fetuses, and the ratio of length to width was calculated. The accuracy of each fetal measurement and Doppler ultrasonography were determined...

A link between congenital vascular malformation (CVM) of the liver and trisomy 21 has been suggested. We reviewed all children with trisomy 21 referred for investigation to a specialist pediatric hepatobiliary unit (1985-2015). Forty-five children with trisomy 21 were identified; 7 (15%) had a defined CVMs (4 girls). All such infants were also diagnosed with a range of cardiac defects. CVMs were divided according to the nature of the vascular connection. Group (i) (n = 3): Abnormal venovenous anomaly. This included portocaval shunt and patent ductus venosus (n = 2)...

The objective of our study was to appraise the incidence and significance of persistent right umbilical vein (PRUV), the most common foetal venous aberration. Based on a south Indian antenatal cohort, we identified 23 cases of PRUV amongst 20,452 foetuses of consecutive pregnancies, from 2009 to 2014, yielding an incidence of 1 in 889 total births (0.11%). The median maternal age was 24 (IQR, 22-26) years, and median gestational age at diagnosis was 23 (IQR, 22-24) weeks. Intrahepatic drainage of PRUV was seen in 91...

OBJECTIVES: To develop a model for the prediction of stillbirth that is based on a combination of maternal characteristics and medical history with first-trimester biochemical and biophysical markers and to evaluate the performance of screening with this model for all stillbirths and those due to impaired placentation and unexplained causes. METHODS: This was a prospective screening study of 76 897 singleton pregnancies, including 76 629 live births and 268 (0.35%) antepartum stillbirths; 157 (59%) were secondary to impaired placentation and 111 (41%) were due to other or unexplained causes...

Abortion of the fetus due to a disease has been dramatically increased in the last decades. There is a still lack of knowledge on the various types of diseases which lead fetus to a vulnerable circumstance. The transport of oxygenated blood from the placenta to the human fetus has been an important clinical feature in Doppler velocimetry studies, especially the Ductus Venosus (DV). The DV connects intra-abdominal portion of the umbilical vein and the Inferior Vena Cava (IVC) at the inlet of the right atrium and is, therefore, important when examining the fetus state of health...

BACKGROUND: Erythropoietin seems to play an important role in the regulation of fetal hypoxemia. The present prospective study was designed to determine if changes in erythropoietin levels can be found in fetuses with severe early-onset growth restriction and hemodynamic compromise. METHODS AND RESULTS: Erythropoietin, hemoglobin, hematocrit, platelet counts, normoblasts, lacate, arterial and venous blood gasses in the umbilical cord were determined in 42 fetuses with fetal growth restriction (IUGR) with absent (zero-flow) and 26 IUGR fetuses with retrograde end-diastolic flow (reverse-flow) in the umbilical artery...

OBJECTIVES: To identify the most common first-trimester ultrasound findings in Turner syndrome (TS). To evaluate which first-trimester findings can be best used to predict the likelihood of TS. METHODS: This was a prospective study, based on singleton pregnancies. The referrals included 6210 patients. Scan protocol covered a review of the early fetal anatomy and markers of aneuploidy. RESULTS: Study population comprised 5644 pregnancies: 5613 with a normal karyotype and 31 cases of TS...

OBJECTIVES: To explore if in early fetal growth restriction (FGR) the longitudinal pattern of short-term fetal heart rate (FHR) variation (STV) can be used for identifying imminent fetal distress and if abnormalities of FHR registration associate with two-year infant outcome. METHODS: The original TRUFFLE study assessed if in early FGR the use of ductus venosus Doppler pulsatility index (DVPI), in combination with a safety-net of very low STV and / or recurrent decelerations, could improve two-year infant survival without neurological impairment in comparison to computerised cardiotocography (cCTG) with STV calculation only...

INTRODUCTION: Human type 1 diabetic pregnancy is associated with placental structural and hemodynamic abnormalities. We hypothesized that in rat fetuses of hyperglycemic dams, placental and fetal blood flow velocity waveforms demonstrate compromised hemodynamics when compared to control fetuses, and these hemodynamic parameters correlate with placental structural abnormalities at near term gestation. METHODS: Streptozotocin-induced maternal hyperglycemia group comprised 10 dams with 107 fetuses and the control group 20 dams with 219 fetuses...

BACKGROUND: In human fetuses with cardiac defects and increased nuchal translucency, abnormal ductus venosus flow velocity waveforms are observed. It is unknown whether abnormal ductus venosus flow velocity waveforms in fetuses with increased nuchal translucency are a reflection of altered cardiac function or are caused by local morphological alterations in the ductus venosus. AIM: The aim of this study was to investigate if the observed increased nuchal translucency, cardiac defects and abnormal lymphatic development in the examined mouse models are associated with local changes in ductus venosus morphology...
