81. Fetal Thoracoamniotic Shunting in a Case of Congenital Pulmonary Airway Malformations with Hydrops Fetalis (Full text)

, abdominal circumference, and amniotic fluid index started increasing from 28 weeks and hydrops worsened. The insufficient shunting and the fetal cardiac failure had to be considered. At 32 weeks, a male infant with general edema and massive ascites was born weighing 3,362 g (+4.79 SD) with Apgar scores of 2 and 4. The infant was intubated and high-frequency oscillation and nitric oxide therapies were instituted. The resection of CPAM was performed on day 2. Nasal continuous positive airway pressure (...) Fetal Thoracoamniotic Shunting in a Case of Congenital Pulmonary Airway Malformations with Hydrops Fetalis Aim  We report a case of congenital pulmonary airway malformation (CPAM) with hydrops in which the fetus underwent thoracoamniotic shunting. Case Report  A 40-year-old (G1P1) woman was diagnosed with a macrocystic CPAM. Thoracoamniotic shunting was performed at 19 weeks of gestation but not well drained and was successfully performed again at 23 weeks. However, the CPAM volume ratio

and nitrogen dioxide (NO2) for in utero fetal growth, size at birth and effect modification by smoking status.Administratively acquired second and third trimester fetal measurements (bi-parietal diameter, femur length and abdominal circumference), birth outcomes (weight, crown heel length and occipito-frontal circumference) and maternal details were obtained from routine fetal ultrasound scans and maternity records (period 1994-2009). These were modelled against residential annual pollution concentrations (...) and abdominal circumference were not significantly associated with pollution exposure.Fetal growth is strongly associated with particulates exposure from later in second trimester onwards but the effect appears to be subsumed by smoking. Typical ambient exposures in this study were relatively low compared to other studies and given these results, it may be necessary to consider reducing recommended "safe" ambient air exposures.Copyright © 2017.

, gestational age ≥34 weeks and ultrasound scan to delivery duration ≤7 days. Cases with fetal growth restriction or malformation were excluded. The cases were divided into standard weight bands of 500 g each based on newborns' actual birth weights (ABW). For each weight band, performance of 12 different models based on abdominal circumference (AC), biparietal diameter (BPD), head circumference (HC) and femur length (FL) was evaluated by mean percentage error (MPE) and its standard deviation (random error (...) A Systematic Evaluation of Ultrasound-based Fetal Weight Estimation Models on Indian Population The purpose of this study was to systematically evaluate ultrasound-based fetal weight estimation models on Indian population to find out their performance across different weight bands and ability to correctly categorize low birth weight (LBW) and high birth weight (HBW) fetuses.We used retrospectively collected data of 154 cases for the study.

of reduced fetal growth rate. The secondary aim was to investigate the relationship between a low cerebroplacental ratio at term, reduced fetal growth velocity, and adverse pregnancy outcome.This was a retrospective cohort study of singleton pregnancies in a tertiary referral center. The abdominal circumference was measured at 20-24 weeks' gestation and both abdominal circumference and fetal Dopplers recorded at or beyond 35 weeks, within 2 weeks of delivery. Abdominal circumference and birthweight (...) values were converted into Z scores and centiles, respectively, and fetal Doppler parameters into multiples of median, adjusting for gestational age. Abdominal circumference growth velocity was quantified using the difference in the abdominal circumference Z score, comparing the scan at or beyond 35 weeks with the scan at 20-24 weeks. Both univariable and multivariable logistic regression analyses were performed to investigate the association between low cerebroplacental ratio and the low abdominal

model to identify distinct groupings (ie, classes) of the Perceived Stress Survey trajectories over pregnancy. Trend analysis was used to determine whether neonatal measurements including birthweight, length, head circumference, and abdominal circumference differed by Perceived Stress Survey class and whether this relationship was modified by maternal race/ethnicity, after adjustment for gestational age at delivery, maternal height, age, and parity.Of the 2334 women enrolled in the study, 1948 women (...) had complete neonatal anthropometry and were included in the analysis. Latent class analysis identified 3 Perceived Stress Survey trajectory classes, with mean Perceived Stress Survey scores of 2.82 (low), 7.95 (medium), and 14.80 (high). Neonatal anthropometric measures of birthweight, length, head circumference and abdominal circumference were similar (P=.78, =.10, =.18, and =.40 respectively), regardless of the participants' Perceived Stress Survey class.

Fetal somatic growth trajectory differs by type of congenital heart disease. BackgroundThe growth trajectories of common measurements, including estimated fetal weight (EFW), head circumference (HC), and abdominal circumference (AC), in fetuses with congenital heart disease (CHD) have not been described for different cardiac lesions. We hypothesized that (i) fetuses with CHD have differential growth in utero, and (ii) different categories of CHD demonstrate different in utero growth (...) curves.MethodsWe performed a retrospective observational cohort study of pregnancies with known fetal CHD seen from January 2000 to June 2013. For analysis, the infants were divided into single ventricle (SV), biventricular conotruncal, d-transposition of great arteries (d-TGA), biventricular septal defects (SD; including atrial, ventricular, and atrioventricular SD), and all others (Other).ResultsA total of 194 newborns met inclusion criteria.

FT4 was also inversely associated with repeated measurements of estimated fetal weight, head circumference, and abdominal circumference. We observed weaker inverse associations for total T4 and a positive relationship between total triiodothyronine and birth weight z scores. We did not observe any associations for thyroid-stimulating hormone.In pregnant women without overt thyroid (...) Subclinical Changes in Maternal Thyroid Function Parameters in Pregnancy and Fetal Growth. Overt thyroid disease in pregnancy is a known risk factor for abnormal fetal growth and development. Data on the effects of milder forms of variation in maternal thyroid function on intrauterine growth are less well examined.We explored these associations using repeated thyroid hormone and ultrasound measurements.Data were obtained from 439 pregnant women without diagnosed thyroid disease who were

UA Doppler velocimetry patterns were obtained.A total of 434 examinations were performed, and centiles were established for biparietal diameter, head circumference, abdominal circumference, femur length, and estimated fetal weight. A significant difference was observed between the gastroschisis measurements when (...) compared to control, with all curves shifted downwards. Abdominal circumference was the parameter presenting the largest difference. Estimated fetal weight was also lower, with mean difference of 256.3 ± 166.8 g for the 50th centile (P < .0001).
