Abstract:

As the number of pregnant women with previous cesareans continues to grow， so too does the incidence of cesarean scar pregnancy （CSP）. Domestic and international guidelines and consensus recommend that a CSP should be terminated once diagnosed. Nevertheless， some pregnant women diagnosed with CSP request to continue the pregnancy for various reasons. Given the significant risks of adverse pregnancy outcomes associated with continuing a CSP， there is a pressing need to enhance our understanding of the relevant literature. The present study undertook a review of the literature on continuing a CSP over the past two decades， to generalize the outcomes of pregnancies. In addition， the association between ultrasound signs in the first trimester and the risks of placenta accreta spectrum disorders，postpartum hemorrhage， uterine rupture， and hysterectomy was also summarized. Furthermore， the appropriate time and method for terminating a CSP after expectancy were discussed. The present review aims to provide more references for better management of CSP.
