Is it necessary to correct a caesarean scar defect before a subsequent pregnancy? A report of three cases

Rates of caesarean section have increased over recent years and so too have associated complications, one of which is a caesarean scar defect (CSD). The defect may cause gynaecological symptoms, such as menometrorrhagia, infertility, chronic abdominal/pelvic pain or it may be asymptomatic. The presence of CSD may lead to obstetrical sequalae such as preterm delivery, uterine rupture, caesarean scar pregnancy or abnormal placenta implantation. Three cases of CSD are described here. In one case, surgical correction of the CSD was performed before a subsequent pregnancy with an uncomplicated obstetric outcome. In the other two cases, surgical correction of the CSD was not performed and the pregnancies were complicated by caesarean scar dehiscence and caesarean scar pregnancy. We suggest that women with a CSD may benefit from surgical correction of the defect before becoming pregnant to reduce the likelihood of serious complications
