Management of fetal growth restriction.

When fetuses are growth restricted as a result of inadequate placental function, there is an increased risk of poor perinatal outcome compared with fetuses where small dimensions are constitutional and associated with normal placental function. The management of reduced fetal size should therefore focus on the identification of the fetus at risk due to placental dysfunction, and longitudinal assessment to reduce the morbidity and mortality associated with this pathology by ideal timing of delivery. The aim of this review is to rationalize the best way to assess fetuses affected in this way and how to improve their outcome by appropriately timed intervention.
