Caesarean scar pregnancy, a rare but emerging problem: an overview of diagnosis, management and potential preventative strategies

With the rate of Caesarean sections rising globally, we are seeing an increase in associated complications. One of these complications is a Caesarean scar pregnancy (CSP). These are ectopic pregnancies that implant into the scar of the previous Caesarean section and are associated with severe maternal and fetal morbidity and mortality. An early diagnosis of CSP and prompt intervention can help to mitigate some of the risks. In this review article we go through the diagnosis and management of CSP. We also present two cases of CSP, both managed in the same way but with very different outcomes, illustrating the complexity of this condition. Finally we review the emerging evidence for prevention of scar niche formation.
