Case of uterine scar rupture in the second trimester of pregnancy after preceding caesarean section

Cover Page


Uterine rupture is one of the rare and severe complications of pregnancy and childbirth. It most often occurs in the third trimester however there are publications on cases of uterine rupture in the second trimester. In the available Russian literature we were unable to find any publications regarding uterine scar rupture in the second trimester after preceding caesarean section; available publications focus on uterine scar rupture after preceding myomectomy. Prevalence of caesarean section has recently increased dramatically both in the world and in Russia, besides the data about possibility of pregnancy prolongation in case of uterine scar rupture appeared. It encouraged us to present clinical observation. It demonstrates that uterine scar rupture in the early stages of pregnancy is paucisymptomatic and is often considered as a threatening miscarriage. It is necessary to remember that threatening miscarriage is usually characterized by shortening and softening of the cervix which are not observed in case of threatening or accomplished uterine scar rupture. As such factors, as the time of uterine rupture symptoms occurence, gestational age, localization of placenta, absence of placenta rotation, fetal viability, size of the uterine scar and the characteristics of scar rupture are the main predictors for the decision of pregnancy prolongation in case of uterine scar rupture, so the early diagnosis of such condition is of great importance.
