Abstract:Cesarean scar pregnancy (CSP) is a special ectopic pregnancy, which mainly shows that the gestational sac and/or placenta are implanted in the scar of the previous cesarean section (limited to gestational weeks≤12 weeks). With the progress of medical imaging, CSP is becoming more and more common, with an incidence of about 1∶1 800. In the past decades, with the increase of cesarean section in China, the incidence of CSP has also risen, and especially after the implementation of the two-child policy in China, the harm of CSP to women has been gradually exposed. CSP is a kind of iatrogenic disease, which may cause serious complications during and after the operation, such as uncontrollable massive bleeding, uterine rupture, peripheral organ damage and even hysterectomy, which seriously threaten the reproductive health and even life of patients. Therefore, early diagnosis and treatment are essential for women. At present, there are different opinions on the pathogenesis of CSP, there are no normalized standards and guidelines and good evidence-based medical evidence at home and abroad for the selection of CSP treatment schemes, and there is a lack of randomized controlled studies with large sample size. Therefore, this article will review the etiology and treatment progress of CSP, in order to provide some reference for the selection of CSP treatment.
