Fetal growth restriction (FGR) is an important and poorly understood condition of pregnancy, which results in significant fetal, neonatal and long-term morbidity and mortality. The aetiology of FGR is unknown and is likely to result from sub-optimal placental implantation and feto-maternal immunological interaction. The diagnostic criteria for FGR vary between studies, and the condition often occurs with preeclampsia (PET). We present a review of studies of maternal cytokines in FGR and compare these with studies of Small for Gestational Age and PET pregnancies.
