Comparative assessment of ultrasound placental and doppler findings in SGA and normal-weight fetuses

Background and Aim : Abstract: Small for gestational age (SGA) refers to newborns whose birth weightis less than the 10 th percentile for gestational age. The purpose of this study was to provide a comparativeassessment of ultrasound placental findings in SGA and normal-weight fetuses in singleton pregnantwomenMethods : Methods: A total number of 112 singleton pregnant women who in their second trimester during2016-17 were selected. Ultrasound placental findings were assessed in SGA and normal-weight fetuses.Fetal and maternal indices were also assessed. Results were compared statistically in SPSS.Results : There was a significant relationship between maternal age and IUGR (0.026), while no significantrelationship was found between gestational age and IUGR (p=0.185). No statistically significant differenceexisted between male and female fetuses in terms of IUGR (p=0.542). The highest artery Doppler systolicdiastolicpressure ratio was found in EFW<5 th percentile which showed a statistically significant differencewith other groups (p<0.01). Uterine artery resistance indices (UARI) in <5 th percentile and > 90 thpercentile groups were the highest and lowest respectively with a statistically significant difference withother groups (p<0.01). Amniotic fluid index was the lowest in 5-10 th percentile and <5 th percentile groups(p<0.01). Placental thickness in the <5 th percentile group was significantly smaller than in other groups(p=0.00), but the difference between 5-10 th percentile and > 10 th percentile groups was not significant(p=0.16).Conclusion : SGA incidence is significantly related to maternal pregnancy age, artery Doppler systolicdiastolicpressure ratio, UARI, AFI, and placental thickness. As such, ultrasound methods can be employedduring pregnancy to detect SGA incidence.
