Methods of preventive intervention in women with multiple pregnancies in non-assymptomic circulation

The aim: The purpose of the study is a comparative evaluating the effectiveness of using the different methods of treatment of miscarriage in multiple pregnancies taking into account the condition of the cervix.

Materials and methods: 86 pregnant women with diarrheal twins were monitored. On the basis of studying the premorbid background, somatic and reproductive history, features of the gestational period, leading antenatal risk factors for the development of complications in multiple pregnancies were identified. With the help of transvaginal cervicometry the prognostic ultrasound criteria of the condition of the cervix and its obstructive capacity in case of premature birth are investigated.

Results: In the event of uncomplicated pregnancy multiple birth is characterized by a gradual shortening of the cervix in dynamics from 43.2 ± 3.9 mm to 38.2 ± 4.0 mm by 20 weeks, from 37.7 ± 4.1 mm to 30.2 ± 3.9 mm to 30 weeks, to 21.1 ± 3.1 mm to 37 weeks. In the period of 25-27 weeks, the appearance of a V-shaped opening of the uterine cervix in half of the women was observed, which remained until the end of gestation. Shortening of the cervix was the most significant in patients with the risk of abortion who received only tocolytic therapy. In the 2nd trimester revealed a V- or U-shaped opening of the cervical canal. In pregnant women at risk who had an obstetric pessary, a decrease in the length of the cervix was found, which was similar to the rate of its shortening in uncomplicated multiple pregnancies. The condition of the cervix in the presence of a pessary before delivery probably did not differ from the condition of the cervix with the normal course of multiple pregnancies.

Conclusions: Pregnant women with uncomplicated multiple pregnancies revealed a decrease in the length of the cervix with an increase in gestation. At the end of pregnancy, the internal jaws acquired a predominantly Y-shape. In pregnant women with the risk of pregnancy termination who received tocolytic therapy, the cervix was the shortest. In late gestation, V- and U-shaped internal jaws were observed. Changes in the cervix after the placement of obstetric pessaries are similar to changes in uncomplicated pregnancy.
