The analysis of the risk factors dysfunction placenta at the obstetric and extragenital pathology - the role of defects uterine hemodynamics in the first trimester of pregnancy in the Genesis of placental insufficiency abortion, gestational pyelonephritis, arterial hypertension, hypotension of pregnant. By the method of vaginal dopplerography were examined 669 study of pregnant women with pathologies and 40 women with physiologically developing pregnancy, received curves velocity of blood flow in the uterine arteries calculated on the basis of which S/D ratio and pulsatility index (PI) in the left and right a. uterinae. These data together with the anamnesis pregnant used for predicting the placental insufficiency. It is proved that the pathological modulation uterine hemodynamics in the first trimester of pregnancy can be used as objective a prognostic marker of placental insufficiency in pregnant with threatening abortion, vascular dystonia and in pregnant without background obstetric and extragenital pathology.
