METHODS: Twenty-seven fetuses with estimated weights below the 3rd percentile for gestational age were evaluated. Placental volume and vascular indices, including vascularization, flow, and vascularization flow indices, were measured by three-dimensional ultrasound using a rotational technique and compared to a previously described nomogram. The observed-to-expected placental volume ratio for gestational age and observed-to-expected placental volume ratio for fetal weight were calculated. Placental parameters correlated with the Doppler velocimetry results of uterine and umbilical arteries. RESULTS: The mean uterine artery pulsatility index was negatively correlated with the observed-to-expected placental volume ratio for gestational age, vascularization index and vascularization flow index. The observed-to-expected placental volume ratio for gestational age and observed-to-expected placental volume ratio for fetal weight and vascularization index were significantly lower in the group with a bilateral protodiastolic notch. No placental parameter correlated with the umbilical artery pulsatility index. CONCLUSIONS: Pregnancies complicated by severe fetal growth restriction are associated with reduced placental volume and vascularization. These findings are related to changes in uterine artery Doppler velocimetry. Future studies on managing severe fetal growth restriction should focus on combined results of placental three-dimensional ultrasound and Doppler studies of uterine arteries.
- Associations of maternal personal exposure to air pollution on fetal weight and fetoplacental Doppler: A prospective cohort study(2016) CARVALHO, Mariana A.; BERNARDES, Lisandra S.; HETTFLEISCH, Karen; PASTRO, Luciana D. M.; VIEIRA, Sandra E.; SALDIVA, Silvia R. D. M.; SALDIVA, Paulo H. N.; FRANCISCO, Rossana P. V.We determined the influence of maternal air pollution exposure during each trimester of pregnancy on fetal and birth weight and fetoplacental hemodynamics. In total, 366 women with singleton pregnancies were prospectively followed in the city of Sao Paulo, Brazil. Nitrogen dioxide (NO2) and ozone (O-3) were measured during each trimester using passive personal samplers. We evaluated fetal weight and Doppler velocimetry data from the umbilical, middle cerebral, and uterine arteries in the 3rd trimester, and birth weight. Multivariate analysis was performed, controlling for known determinants of fetal weight. Exposure to higher levels of O-3 during the 2nd trimester was associated with higher umbilical artery pulsatility indices (PIs) [p = 0.013; beta = 0.017: standard error (SE) = 0.007]. Exposure to higher levels of O-3 during the 3rd trimester was associated with lower umbilical artery PIs (p = 0.011; beta = 0.021; SE = 0.008). Our results suggest that in the environment of Sao Paulo, 03 may affects placental vascular resistance.
