Cervical insufficiency is one of the most frequent reasons for late miscarriage and preterm birth. Its rate is increased in women who conceived after the use of additional reproductive technologies. The objective: to assess the parameters of cervical elastography in women with cervical insufficiency and anovulatory infertility in a history. Materials and methods. 40 pregnant women with cervical insufficiency who conceived after treatment of infertility associated with anovulation were examined in the term of 16–20 weeks: in the I group (20 persons) pregnancy conceived after conservative treatment of infertility, in the II (20 patients) – after in vitro fertilization. 20 women with the physiological course of pregnancy without cervical insufficiency and with spontaneous gestation were controls. Cervical elastography index was used to assess the strain of cervical tissue. Results. According to the results of compression elastography all patients in the I and II groups had red or yellow color of the internal cervical os and cervical canal. In the persons without cervical insufficiency the cervical tissue was firm (purple and blue color). The number of women with purple color of the anterior labia of the cervix in the I and II groups was in 4.67 (р=0.001) and 2.33 (р=0.03) times less compared to the controls, of the posterior labia – in 3,2 times (р=0.001) in both groups. Conclusion. In women with cervical insufficiency and a history of anovulatory infertility there are considerable changes of strain in internal os and cervical canal of the cervix.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
