MATERNAL HAEMODYNAMIC AND HAEMORRHELOGIC CONSIDERATIONS IN FETAL I.U.G.R.

IUGR is a symptom which has many causes; genetic abnormalities, feto-maternal infections, maternal drug intake, smoking, socio-demographic factors, all are related to fetal IUGR, but the most common underlying cause is the inadequate or inappropriate placental function. This is obvious because placenta plays a central role in fetal nutrition and there is no survival of the fetus in utero without the support of the placenta. The diminished fetal growth rate can be considered äs an intrauterine mechanism of defence against hypoxic damage, because in this way there is a saving of oxygen for the cerebral tissue.
