Reproductive Losses

The study presents data of different authors, as well as its own data on the frequency of multiple trisomies among the early reproductive losses in the I trimester of pregnancy and live fetuses in pregnant women at high risk of chromosomal abnormalities (CA) in I and II trimesters of gestation. The objective: determining the frequency of occurrence of double (DT) and multiple trisomies (MT) among the early reproductive losses in the I trimester of pregnancy and live fetuses in pregnant women at high risk of occurrence of HA in I and II trimesters of gestation; establishment of the most common combinations of diesel fuel and the timing of their deaths compared with single regular trisomy; comparative assessment materinskogo age with single, double and multiple trisomies. Patients and methods. During the period from 1997 to 2016, the first (primary) group of products in 1808 the concept of missed abortion (ST) of I trimester was formed from women who live in Dnepropetrovsk, Zaporozhye, Kirovograd, Cherkasy, Kherson, Mykolaiv regions. The average term of the ST was 8±3 weeks. The average age of women was 29±2 years. The second group (control) consisted of 1572 sample product concepts received during medical abortion in women (mostly residents of Krivoy Rog) in the period of 5-11 weeks of pregnancy, the average age was 32 years. The third group was made prenatally karyotyped fruits (n = 9689) pregnant women with high risk of HA of the above regions of Ukraine, directed the Centre to invasive prenatal diagnosis for individual indications: maternal age, changes in the fetus by ultrasound (characteristic malformations and echo markers HA) and high risk of HA on the results of the combined prenatal screening I and II trimesters. From 11 th to 14 th week of pregnancy, chorionic villus sampling was performed (n=1329), with the 16th week – platsentotsentez (n=2240), 18 th and 24 th week – amniocentesis (n=6120). Results. A comparative evaluation of maternal age and the prevalence anembriony among multiple trisomies. Analyzed 13,069 karyotyped embryonic and fetal I-II trimester of which have found 40 cases of multiple trisomies – 31 cases in the group in 1808 missed abortion (2.84% of total HA), 3 cases including 1 572 induced medabortov and 7 cases during 9689 prenatal research (0.51% of HA). Determined to share the double trisomies preembrionalny, fetal, early, middle and late periods of fetal development. Conclusion. There were no significant differences either in terms of destruction of single and multiple trisomies or in maternal age or in fractions anembrionalnyh pregnancies in these groups. Key words: multiple trisomies, double trisomy, missed abortion, prenatal diagnosis.
