Abstract：Fetal growth restriction (FGR) refers to the restriction of fetal growth and development in uterus due to various pathological factors, which can not achieve its genetic growth potential. Maternal, fetal, placental and umbilical factors may lead to FGR. At present, there is no golden standard for diagnostis of FGR; thus it is of great significance to strengthen the perinatal monitoring of FGR. The perinatal monitoring methods of FGR include measurement of symphysio-fundal height (SFH), B-ultrasonography, Doppler ultrasonography, serological detection and genetic means. However, single index in the prediction and diagnosis of FGR is limited. Most of the detection methods are for early-onset FGR, while their sensitivity and specificity for late-onset FGR are low. Future studies need to focus on early and accurate identification of FGR for early intervention, in order to reduce the incidence of adverse pregnancy outcomes.
