Among malignancies Cervical cancer is the second place in the structure of cancer incidence in women. In recent years there has been a negative trend in increasing the frequency of benign disease and cervical cancer in young women. Women with destructive treatment of cervical intraepithelial neoplasia frequency increases a history of infertility, spontaneous abortion, premature birth, fetal infection and other complications in childbirth and the postpartum period. Therefore, pregnancy, development of the embryo and fetus largely depend on the availability of prenatal viral infections, but the data of the literature on this subject is very controversial.The purpose of the study is to examine to complications of obstetric and perinatal period in pregnant women with destructive treatment of cervical intraepithelial neoplasia in a history Materials and methods. To achieve this goal we held clinical-statistical analysis of 100 individual maps of pregnancy, childbirth stories and maps of infants were divided into 2 groups. I group (basic) - 50 patients with cervical intraepithelial neoplasia cervical history and II (control) - 50 somatically healthy pregnant women without this disease in history. All pregnant women conducted a comprehensive survey that included: clinical, microbiological, instrumental, cytological, colposcopic study , definition of vaginal microbiota and the detection of infections transmitted sexually.RCD status placenta and Doppler a.umbilicalis conducted in pregnant women in the group of subjects in different stages of pregnancy.Results and discussion. In the main group 50 women had a history of CIN place varying degrees of severity. It should be noted that women have a history of diagnosed ureaplasmosis, mycoplasmosis and chlamydia, that was not characteristic of the control group. Women and control group there was a history of early abortion threat, the threat of late spontaneous abortion and threatened preterm labor. In a comprehensive survey in the study group revealed: placental dysfunction, fetal distress, intrauterine growth retardation (IUGR) . Polyhydramnios and oligohydramnios. For the control group was characterized by IUGR and oligohydramnios.From anomalies of labor activity in the treatment of pregnant women with CIN destructive history observed: primary weakness of labor activity, secondary weakness of labor and incoordination generic activities. Premature detachment of normally situated placenta diagnosed only in the main group of women and fetal distress in labor (ie in the first and second periods genera). More than half of the main group of women, childbirth ended per vias naturales.The most common indications for caesarean section for the main group were: failure scar on the uterus, premature detachment of normally situated placenta, fetal distress and extragenital pathology. Comparing the two groups Apgar found that newborns of the group worst figure for 1 minute than in the control group. It has been found that of early neonatal period was complicated only in infants who were born to women with CIN treatment destructive in history. Developmental abnormalities in infants were found, as were pregnant timely diagnosis and prenatal screening ultrasound examination as recommended by gynecologists.Conclusions.1. The threat of early termination of pregnancy, late spontaneous abortion and premature birth more common in women of the main group than in the control group.2. Comprehensive examination in the study group revealed placental dysfunction and fetal distress that was not characteristic of the control group.3. Comparing the two groups Apgar found that newborns of the basic group was with worst figure for 1 minute than in the control group.4. The early neonatal period was complicated only in infants who were born to women with a history of CIN.
