[Comparative study of dopplerometry and morphological study of placenta and uterine arteries in the evaluation of hemodynamic disorders in the "mother-placenta-fetus" system]. / Sravnitel'nyi analiz Dopplerometrii i morfologicheskogo issledovania platsenty i spiral'nykh arterii v otsenke gemodinamicheskikh narushenii v sisteme mat'-platsenta-plod.

The paper gives the comparative results of Doppler examination of blood flow in the mother-placenta-fetus system and morphological examination of the vessels of the funis, placenta, and placental bed. The latter examination allowed all the cases of placentomaternal and placentofetal circulatory diseases to be divided into 3 groups. There was a clear-cut correlation between the Doppler metric and morphological findings.

The comparison of the spiral uterine arteries structure, umbilical vessels and placenta is performed in 16 women with normal haemodynamics and in 31 women with disturbances of mother-foetus circulation, and the data obtained were compared with results of dopplerometry made before the delivery. Three clinical groups are distinguished according to the predominant localization of the resistance to the blood flow: the first--with the domination of the spiral arteries obliteration (lack of gestational changes, hyperplastic arteriosclerosis) with a characteristic ultrastructural pathology of the syncytiotrophoblast microvilli, rheological disturbances in the intervillous space and large necroses of villi; the second--with a predominance of early immaturity of the stroma and capillaries or sclerosis and compression of foetal villous capillaries, i. e. with a reduction of a capillary bed and increase of the resistance to the blood flow; the third--with a predominance of the umbilical arteries narrowing and supporting villi and signs of a blood stasis in the foetal veins. Morphologic heterogeneity of the mother--foetus circulation disturbances should be taken into consideration when choosing obstetric tactics.
