... tility outcomes of two methods in treating patients with cesarean scar pregnancy (CSP) after receiving uterine artery embolization (UAE) treatment.Patients and methods: A total of 62 CSP patients who visited our hospital and underwent UAE from January 2013 to January 2018 were retrospectively analyzed. Patients were either treated by dilation and curettage (D&C) guided by ultrasonography or hysteroscopy. The differences of related clinical indicators, clinical efficacy, complications, and subsequent fertility outcomes between the two groups were analyzed.Results: The rates of therapeutic success of the ultrasonography group and hysteroscopy group were 84.6% and 95.7%, respectively, the difference was not statistically significant (P=0.243). However, the intraoperative blood loss, duration of hospitalization, and overall complications were significantly lower in hysteroscopy group compared with D&C guided by ultrasonography group (P<0.05 for all). Meanwhile, hysteroscopy had the advantage of discovering potential diverticulum in the lower segment of anterior wall of uterus (P<0.001).Conclusion: D&C guided by ultrasonography or hysteroscopy for the treatment of CSP after UAE resulted in similarly good clinical outcomes. Compared with treatment of D&C guided by ultrasonography, hysteroscopy had less complications and had the advantages of discovering diverticulum. It can be used as an effective way for the treatment of CSP. Keywords: cesarean scar pregnancy, uterine artery embolization, dilation and curettage, ultrasonogra [...]
