Abstract:
Fetal growth restriction (FGR) is defined as the fetus does not reach its biological growth potential as a consequence of impaired placental function. Currently, the biggest clinical problem in this field is how to distinguish FGR fetus from healthy small for gestational age (SGA) fetus. Ultrasonography was regarded as golden criteria in diagnosis of FGR. The key diagnostic indexes included abdominal circumference (AC), estimated fetal weight (EFW) and umbilical artery (UA) blood flow spectrum curve. Ultrasonic monitoring can help to predict the adverse perinatal outcomes and select the optimal time of delivery. Some monitoring indexes, including growth parameters such as EFW and AC, resistance index of UA, ductus venosous Doppler waveform, middle cerebral artery, cerebroplacental ratio, as well as resistance index of uterine artery have been proved to be helpful to monitoring and prognosis of FGR.
