[Placenta and hypotrophy of the fetus].

The authors analyzed 50 cases of foetal hypotrophy using morphological methods. In the introduction of their paper they reviewed findings reported in the literature on placental causes and briefly also data on the sequelae of foetal hypotrophy for the foetus. Bioptic examination of the placenta can help to differentiate between foetal hypotrophy and immaturity. In foetal hypotrophy of placental origin it is important to differentiate between a primarily hypoplastic placenta (associated sometimes with congenital malformations of the foetus) and secondary insufficient placentas due to impaired uteroplacental circulation or other causes. In some instances both basic disorders may combine.
