(Abstracted from Fetal Diagn Ther 2017;42:174–180)
Literature has shown that conventional chromosomal anomalies can account for up to 19% of fetal growth restrictions (FGRs) when those with anomalies are included. The majority of these anomalies are triploidy if the fetus is less than 26 weeks and trisomy 18 when equal to or greater than 26 weeks' gestation.
