The objective: to develop the early ехографічні criteria of risk of premature births at multiple pregnancy.
Materials and methods. Work is based on the analysis of results of pregnancy in 207 pregnant with twins, from what 137 observed with the use of the developed algorithm and 70 on a standard method, accepted for a singleton pregnanacy. The term of pregnancy was determined from the first day of the last menstruation, taking into account information of bimanual research in women’s
consultation and ultrasonic research in the early terms of pregnancy. Depending on character of choriality were selected 2 basic groups: «dichorionic diamniotic twins» – 146 women and «monochorionic diamniotic twins» is a 61 woman. Choriality was set at ultrasonic research in 10–14 weeks on the basis of determining the amount of placentas, and during visualization of one placenta the place of opening of the amniotic septum was studied.
Results. By the most early prognostical criterion of premature births to 36 weeks gestation we suggest to count shortening of the cervical canal to 38 mm at pregnancy 18 weeks. A sensitiveness of this criterion in our research was 78%, specificity 97%, relation of credibility of positive result of test 26,0, relation of credibility of negative result of test 0,2. At shortening of the cervical canal in 18 weeks of gestation to 35 mm sharply grows authenticity of premature births to 34 weeks gestation with a sensitiveness 78,5% and by specificity 100%. Length of cervical canal 30 mm in 18 weeks of gestation we suggest to consider critical, as at such value births to 34 weeks gestation in our research happened for all women, a sensitiveness of criterion was 100%, specificity – 100%.
Conclusions. The adequate prophylaxis of premature births is mine-out in 55 (40,2%) pregnant. Among 137 pregnant births to 36 weeks gestation happened in 35 (25,5%), that for certain below than indexes of experimental group (p < 0,02). The got results must be plugged in the algorithm of diagnostic and treatment-and-prophylactic measures at a multiple pregnancy.
