title: [Echomorphologic parallels in the ultrasound examination of the placenta].
abstract: Results of the ultrasound and morphological examination of the villous chorion of women with physiological pregnancy (34 cases) and with late pregnancy toxicoses (280 cases) were compared. A gradual decrease of the chorion acoustic density in physiological pregnancy correlates with a development of the compensatory-adaptive reaction (CAR) on the tissue level and serves a favourable prognosis for the pregnancy outcome. In patients with late pregnancy toxicosis, alterations of the chorion echogenicity occur at different periods of the pregnancy and reflect the CAR disturbances facilitating the development of various forms (stages) of the placenta insufficiency. The results obtained indicate possibilities of placentography use for a differential approach to the choice of methods and terms of delivery in late pregnancy toxicoses.
