Successful Treatment of a Recurrent Cesarean Scar Pregnancy by Transvaginal Cesarean Scar Pregnancy Lesion Resection: A Case Report.

Background: Cesarean scar pregnancy (CSP) is a type of ectopic pregnancy with the gestation sac located on a previous cesarean scar. Recurrent CSP (RCSP) is the occurrence of 2 or more consecutive CSPs. Until this case, there have been only 8 previous reported cases of RCSPs in the English-language literature.

Case: A 30-year-old, Chinese woman was admitted to our hospital for RCSP. We had successfully terminated her first CSP by a series of treatments including uterine arterial embolization with local methotrexate injection, mifepristone, and misoprostol administration, as well as an ultrasound-guided suction curettage evacuation. However, this time we performed only a transvaginal CSP lesion resection, which achieved an improved outcome.

Conclusion: This case highlights the likelihood of RCSP and the need for transvaginal CSP lesion resection to decrease the risk of RCSP in CSP patients who desire future pregnancy.
