Early fetal growth restriction (FGR) is a leading cause of perinatal morbidity and mortality. No therapeutic strategies have proved to be effective in improving fetal and neonatal outcomes either in growth restricted fetuses or any placenta-related disorder such as preeclampsia. Delivery of the fetus and placenta is the only definitive cure. However, recent studies suggest that pravastatin appears to be safe in pregnancy, improves placental perfusion and fetal growth and prevents angiogenic imbalance. Angiogenic (PlGF) and antiangiogenic (sFlt-1) factors and feto-maternal Doppler evaluation are strongly associated with fetal growth restriction prognosis and severity. Thus, pravastatin has been proposed as a promising therapeutic drug for fetal growth restriction. We report the findings of a case of early-onset FGR treated with pravastatin 40mg daily until delivery. During this time, feto-maternal Doppler and angiogenic profile evolution were recorded. Fetal and placental perfusion observed on Doppler and angiogenic imbalance improved after pravastatin was started. sFlt-1 down-regulation was more marked than PlGF up-regulation. The patient developed severe preeclampsia (PE) at 27+6 weeks of gestation, necessitating immediate fetal extraction owing to hypertension refractory to adequate treatment. This report supports further investigation on the use of pravastatin to improve angiogenic profile and feto-maternal circulation in FGR fetuses.
