and placental one disorders areis the main causes of FGR. The most common placental factor related to FGR is maternal vascular malperfusion (MVM)

which is caused by transformation defects of spiral arteries in the first trimester. In addition

some rare placental disorders

such as subchorionic hematoma（Breus’ mole）

placental mesenchymal dysplasia and triploidy are also associated with FGR. Prenatal detection of placental anomalies can assist in clarifying the etiology of FGR

and is of great significance in to appropriate antenatal management. The aim of his paperthis review is to review describe ultrasound features of placental disorders associated with FGR.
