THE EFFECTIVENESS OF THE OBSTETRIC PESSARY FOR THREATENING PRETERM BIRTH AND SHORT CERVIX

Preterm birth is one of the most important problems of modern obstetrics. The etiology of preterm birth is multifactorial, including the maternal and fetal complications, on the background of functionally vulnerable variants of many genes, therefore preterm birth is considered as the big obstetric syndrome. One of the anatomical components of the syndrome is the uterine cervix. Frequently, in singleton pregnancy, single-most reliable prognostic marker is the untimely maturation of the cervix due to increased uterine contractile activity.The selection of correction method for the short cervix relies on the clinical conditions, history, gestational age, number of fetuses, cervicometry data, gynecological examination data, threatening preterm birth or pregnancy loss, and the experience of the physician. Insertion of obstetric pessary is a promising, safe, simple method for treatment and prophylaxis of cervical insufficiency and threatened termination of pregnancy in II and III trimesters. The strategy of broad use of pessaries in the group of high-risk pregnant women allows to reduce the frequency of preterm birth and improve perinatal outcomes
