Objective of the study: Comprehensive assessment of risk factors, the implementation of which leads to FGR with early and late manifestation. To evaluate the results of the first prenatal screening: PAPP-A, B-hCG, made at 11-13 weeks. Materials and Methods: A retrospective study included 110 pregnant women. There were 48 pregnant women with early manifestation of fetal growth restriction, 62 pregnant women with late manifestation among them. Results of the study: The risk factors for the formation of the FGR are established. Statistically significant differences in the indicators between groups were not established in the analyses of structures of extragenital pathology. According to I prenatal screening, there were no statistical differences in levels (PAPP-A, b-hCG) in the early and late form of FGR.

Small for gestational age (SGA) and fetal growth restriction (FGR) is difficult to define exactly. In this pregnancy condition, the fetus does not reach its biological growth potential as a consequence of impaired placental function, which may be because of a variety of factors. Fetuses with FGR are at risk for perinatal morbidity and mortality, and poor long-term health outcomes, such as impaired neurological and cognitive development, and cardiovascular and endocrine diseases in adulthood. At present no gold standard for the diagnosis of SGA/FGR exists. The first aim of this review is to: summarize areas of consensus and controversy between recently published national guidelines on small for gestational age or fetal growth restriction; highlight any recent evidence that should be incorporated into existing guidelines. Another aim to summary a number of interventions which are being developed or coming through to clinical trial in an attempt to improve fetal growth in placental insufficiency. Key words: fetal growth restriction (FGR), Small for gestational age (SGA)

Literature reports of placental mosaicism, including trisomy 22, were analyzed. The chance of correlation of placental aneuploidy with fetus aneuploidy, also the probability of complications in pregnancy and fetal growth restriction and postnatal patients growth in the cases of confined placental mosaicism, were demonstrated. The case of prenatal diagnosis of confined placental mosaicism of trisomy 22 with favorable outcome is presented. The necessity of cytogenic assay of amniocytes and fetal lymphocytes in the case of placental heteroploidy diagnosis was emphasized.

Background: This study was aimed to evaluate the effect of sildenafil citrate on Doppler velocity indices in patients with fetal growth restriction (FGR) associated with impaired placental circulation.Methods: A double-blinded, parallel group randomized clinical trial (clinicaltrials.gov NCT02590536) was conducted in Ain Shams Maternity Hospital, in the period between October 2015 and June 2017. Ninety pregnant women with documented intrauterine growth retardation at 24-37 weeks of gestation were randomized to either sildenafil citrate 25 mg orally every 8 hours or placebo visually-identical placebo tablets with the same regimen. The primary outcome of the study was the change in umbilical artery and fetal middle cerebral artery indices.Results: There was a significant improvement in umbilical and middle cerebral artery indices after sildenafil administration p<0.001. Present study observed that, sildenafil group, in comparison to placebo, has a significantly higher mean neonatal birth weight. 1783±241g vs 1570±455g (p<0.001). There was a significantly higher mean gestational age at delivery in women in sildenafil group 35.3±1.67 weeks, whereas it was lower in the placebo group 33.5±1.7 weeks. The side effects as headache, palpitation and facial flushing were significantly higher in sildenafil group compared to placebo group.Conclusions: The use sildenafil citrate in pregnancies with fetal growth restriction (FGR) improved the feto-placental Doppler indices (pulsatility index of umbilical artery and middle cerebral artery) and improved neonatal outcomes.
