Background
Small for gestational age (SGA) refers to newborns whose birth weight is less than the 10^th percentile for gestational age. The aim of this study was to provide a comparative assessment of ultrasound placental findings in SGA and normal-weight fetuses in singleton pregnant women.
Materials and Methods
In this cross-sectional study, a total number of 112 singleton pregnant women who were in their second trimester and referred to Shariati and Imam Khomeini hospitals, Tehran, Iran, during 2016-17 were selected. Ultrasound placental findings were assessed in SGA and normal-weight fetuses. Fetal and maternal indices were also assessed. Data were analyzed using SPSS software (version 16.0).
Results
There was a significant relationship between maternal age and IUGR (0.026); while no significant relationship was found between gestational age and IUGR (p=0.185). No statistically significant difference existed between male and female fetuses in terms of IUGR (p=0.542). The highest artery Doppler systolic-diastolic pressure ratio was found in EFW90th percentile groups were the highest and lowest respectively with a statistically significant difference with other groups (p<0.01). Amniotic fluid index was the lowest in 5-10th percentile and Conclusion
Based on the results, SGA incidence was significantly related to maternal pregnancy age, artery Doppler systolic-diastolic pressure ratio, UARI, AFI, and placental thickness. As such, ultrasound methods can be employed during pregnancy to detect SGA incidence.
