Effects of uterine artery embolization combined with B-ultrasound-guided curettage in the treatment of cesarean scar pregnancy

Abstract

Objective To investigate the clinical effects of uterine artery embolization (UAE) combined with B-ultrasound-guided curettage in the treatment of cesarean scar pregnancy (CSP). Methods The clinical data from 82 patients with CSP treated in Nanyang Second People’s Hospital from January 2016 to May 2018 were retrospectively analyzed. According to their treatment methods, enrolled patients were divided into UAE combined with B-ultrasound-guided curettage group (UAE group, 44 cases) and drug combined with B-ultrasound-guided curettage group (drug group, 38 cases). The bleeding volume during curettage, treatment success rate, recovery condition, including negative conversion time of β human chorionic gonadotropin (β-HCG), vaginal bleeding time, menstrual recovery time, hospital stay, and occurrence of complications of the two groups were recorded. Moreover, the ovarian reserve function indexes, such as follicle stimulating hormone (FSH), anti-Mullerian hormone (AMH), inhibin B (INHB), were compared between the two groups before treatment and after 6 months of treatment. Results The bleeding volume during curettage, β-HCG negative conversion time, vaginal bleeding time, menstrual recovery time and hospital stay in UAE group were significantly lower than those in drug group (P 0.05). There were no significant differences in ovarian reserve function (FSH, AMH, INHB) between the groups and within the groups before and after treatment (P>0.05). Conclusions UAE combined with B-ultrasound-guided curettage has significant effects in the treatment of CSP. It has a high treatment success rate and can reduce the intraoperative bleeding volume, which is beneficial to promoting postoperative recovery.
