Fetal hemodynamic changes can occur immediately following invasive chorionic villus sampling (CVS). We decided to study the possible effect of CVS on fetal heart rate (FHR), and uteroplacental resistance index (RI) changes using color Doppler ultrasound. Thirty-five pregnant patients with a gestational age of more than 12 weeks were included. Trans-abdominal CVS was done to assess the possibility of thalassemia. Before and after the CVS, color Doppler ultrasound was done to measure FHR and uteroplacental RI. Mean (SD) values for FHR before and after the CVS were 175.22 (±9) and 173.62 (±9.94) beats per minute, respectively; P=0.18. Mean (SD) uteroplacental RI before the CVS was 0.79 (0.07) which significantly increased to 0.82 (0.08); P=0.03. We observed a significant increase in resistance of blood flow in placental circulation after CVS. However, no significant change was observed regarding FHR after CVS.

Chorionic villus sampling (CVS) is an invasive method for identifying genetic and metabolic diseases, which is done in the first trimester of pregnancy and can cause many complications. The aim of this study is the evaluation of the correlation between Transabdominal chorionic villus sampling and fetal distress in color Doppler sonography. This study is experimental (before and after). All pregnant women with minor thalassemia in which their husbands were suffering from minor thalassemia or have a history of a child with major thalassemia and after the 12th week of pregnancy were referred to the ultrasound department. RI for fetal Middle Cerebral Artery (MCA) and Umbilical Artery (UA) before and after of CVS were measured and then statistically analyzed using SPSS 22. CVS did not cause a significant increase in RI for the fetal middle cerebral artery (P>0.05). CVS did cause a significant increase in RI for the umbilical artery (P<0.05). Then, CVS did cause a significant decrease in the ratio of RI for fetal Middle Cerebral Artery to RI for Umbilical Artery (P<0.05). Based on these results, it seems that CVS can cause distress in the fetus.

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.

Meckel — Gruber syndrome (MGS) is a rare lethal autosomal recessive disorder characterised by occipital encephalocele, polydactyly and bilateral dysplastic cystic kidneys. A case of prenatal diagnosis of MGS at 12 weeks of gestation is described. The previous pregnancy was terminated at 20 weeks due to polycystic kidneys of the fetus. The transabdominal scan of the present pregnancy revealed occipital encephalocele of the fetus. There was no oligohydramnios, but the fetal urinary bladder was not visualised and both kidneys were enlarged. The transvaginal sonogram demonstrated intracranial space dilatation (6 mm) and encepalocele with posterior fossa cyst, protrunding from the occipital bone deffect. The kidneys had the polycystic structure suggesting cystic dysplasia and there was no evidence of the hands and feet polydactyly. Based on these findings the diagnosis of the MGS was made. Chorionic villus sampling revealed 47,XYY. The family elected to terminate pregnancy and the diagnosis was confirmed by autopsy.
