[The placental structural organization in pulmonary tuberculosis].

The placentas taken from 83 pregnant women with gestation of 37-40 weeks were morphologically and morphometrically studied. Group 1 comprised 23 pregnant women with pulmonary tuberculosis. Group 2 included 40 pregnant women whose pregnancy was complicated by gestosis. Group 3 (control) consisted of 20 healthy pregnant women. Group 1 was found to have chronic placental insufficiency caused by abnormal placental villous immaturity the basis of which was impaired processes of villous differentiation and terminal villous angiogenesis. In most cases, chronic placental insufficiency was compensatory in all the groups under study; but there were differences in compensatory mechanisms. The leading mechanism was cellular in Groups 1 and 2, the mixed (vascular and cellular) types of compensation was predominant in Group 3 (control).

The study is carried out on 200 women, pregnant for first and second time with normally progressing, pregnancy and delivered by normal mechanism at term, who are divided into groups according to the localization of the placenta, established by ultrasound examination. The number of primiparas is 50% in each group. The authors find that when the placenta is located on the uterine fundus larger children are born and hypokinetic labour activity is observed as well as protracted delivery. The site of the placenta is extremely important factor, affecting course of pregnancy and delivery.
