“…This estimation is based primarily on ultrasound estimation of fetal weight between 31 and 34 weeks, and calculation of the mean weekly weight gain using one of the two established formulae, based on umbilical RI measured during this same ultrasound. It is well established that fetal growth is not linear and that umbilical RI classically decreases during the third trimester of pregnancy, but what the present study has shown is that there is a correlation between umbilical RI measured between 31 and 34 weeks of gestation and the mean fetal growth during the third trimester of pregnancy.…”

“…The benefit of umbilical Doppler assessment in low‐risk pregnancies, however, remains controversial, and the meaning of normal or low umbilical RI in this group is unclear . A small number of studies on the subject have suggested a correlation between umbilical RI and birthweight in low‐risk pregnancies …”

“…To our knowledge, this is the largest study to date investigating UADS in normally grown fetuses. A prospective cohort study by Bolz et al investigated the use of UADS in predicting SGA, where elevated PI was associated with higher rates of SGA neonates [14]. In that study, 30% of women with an elevated PI had an SGA neonate, similar to the percentage seen in our population.…”

“…Despite such recommendations, physicians and ultrasonographers are sometimes left with abnormal results in normally grown fetuses when performing a Doppler study. Studies that examine the associations between abnormal UADS in normally grown fetuses and adverse perinatal outcomes are limited [14][15][16][17].…”

Objective: To determine whether there is a relationship between abnormal umbilical artery Doppler studies (UADS) and small for gestational age (SGA) birth weight and other adverse perinatal outcomes in fetuses that appear normally grown by ultrasound. Methods: This was a retrospective study of all women who had UADS performed at or after 26 weeks of gestation at our institution between January 2005 and December 2012. Women were excluded if they had a fetal demise, a fetus with growth restriction, a fetus with congenital anomaly, or a multiple gestation. Women with missing delivery outcomes were excluded. The primary outcome was birth weight below the 10th percentile. Results: There were 2744 women included in the study. Of those, 98 (3.6%) had an abnormal UADS, and 379 (13.8%) had an SGA neonate. Of the 2646 women who had a normal UADS, 353 (13.3%) women had an SGA neonate. Twentysix (26.5%) of the 98 women who had an abnormal UADS had an SGA neonate. After adjusting for potential confounders, the adjusted odds ratio for an SGA neonate with an abnormal UADS was 2.2 (95% CI, 1.38-3.58; p < 0.05). In examining other adverse perinatal outcomes, neonatal intensive care unit (NICU) admission and low 5-min Apgar scores were 12.4 and 2.3%, respectively. The adjusted odds ratio for NICU admission was 1.84 (95% CI, 1.06-3.21; p < 0.05). Abnormal UADS was not associated with low Apgar scores (aOR 1.39: 95% CI 0.47-4.07; p > 0.05). Conclusions:Our data suggest that abnormal UADS in fetuses that appear normally grown by ultrasound are associated with SGA neonates and NICU admission.

An excess of maternal androgen adversely affects the implan tation process and contributes to uterine circulatory disturbances and myometrium vessel sclerosis. Placental insufficiency is typi cally diagnosed at the end of the second trimester of pregnancy or at the beginning of the third trimester, when the treatment is not effective.Many researchers have attempted to use early sonographic diagnostics to identify placental failure in various pathological states. Nevertheless, the peculiarities of the formation of the fetal-placental complex during the first and second trimesters are still undefined. In this study, we traced the process of placental formation under conditions of excess maternal androgen using ultrasound and Dopplerometry. Morphological examinations of the сhorion and placental tissue were undertaken to сompare any changes.Unfavorable chorion locations, heterogeneous chorion tis sue structures, and marginal sinus dilatations were revealed by ultrasound. According to a Dopplerometric investigation, a statistically significant increase in peripheral vessel resistance in cases of hyperandrogenism was identified compared with healthy pregnancies. The negative influence of hyperandrogenism on placental formation was confirmed by morphologi cal data (including the presence of immature decidual cells, defec tive villi that covered the epithelium, and the dissociative development of cotyledons).
