Uterine artery embolization combined with ultrasound-guided dilation and curettage for the treatment of cesarean scar pregnancy: Efficacy and 5-8-year follow-up study.

OBJECTIVE

To evaluate the efficacy and safety of uterine artery embolization (UAE) combined with dilation and curettage (D&C) using ultrasound as a treatment for cesarean scar pregnancy (CSP) and assess its effect on ovarian and reproductive function.

METHODS

A total of 54 patients with uterine CSP between January 2011 and December 2015 were included in this retrospective study. The patients were treated with UAE combined with D&C using ultrasound for the treatment of CSP and followed up for 5-8 years. Their medical records, medical histories, clinical manifestations, treatment courses, and treatment results were analyzed.

RESULTS

The 54 patients were initially treated without severe complications. β-Human chorionic gonadotropin (β-hCG) normalization took 36.11 ​± ​10.73 days (range, 25-84 days), length of hospitalization was 6.6 ​± ​1.5 days (range, 4-10 days), and total blood loss was 18.48 ​± ​8.41 ​mL (range, 5-33 ​mL). All patients resumed normal menstruation after 33.48 ​± ​8.71 days (range, 26-70 days). At the 5-8-year follow-up after UAE combined with D&C by ultrasound for the treatment of uterine CSP, the menstrual volume in 32 (59.3%) patients decreased versus before the operation. Compared with pretreatment, the menstrual cycle was prolonged in two (3.7%) cases, shortened in 10 (18.5%) cases, irregular in one (1.9%) case, and unchanged in 39 (72.2%) cases. Three patients conceived naturally and successfully gave birth to healthy children. Seven (12.96%) patients with accidental natural pregnancies chose induced abortion with no significant change in their sex lives.

CONCLUSION

UAE combined with D&C using ultrasound for the treatment of uterine CSP is safe and effective and may not affect the fertility of patients aged <40 years. However, menstrual volume may be reduced in some patients.
