Taking into account a couple of extra-factors we succeeded to prevent the birth of abnormal children in 10% cases. To assess the possibility of pregnancy complications prognosis we have ultrasonographically studied the features of extraembryonal structures development in 1st trimester pregnancy. We have observed the high prognostic value of chorionic and amniotic cavities volumes and yolk sac pathology in predicting the preterm delivery and IUGR.
