Successful Termination of a Cesarean Scar Ectopic Pregnancy with Systemic Methotrexate and Local Potassium Chloride Injection

Cesarean Section Scar Ectopic Pregnancy (CSEP) is a rare but serious condition in which the embryo implants within the myometrium of a previous C-section scar. This can lead to maternal complications such as abnormal placentation, hemorrhage, or death due to uterine rupture. Despite these grave consequences, a standardized treatment protocol has not yet been established. The data remains limited given the rarity of the occurrence. This case report describes a patient who was diagnosed with a CSEP at 7 weeks gestation. She was successfully treated with a combination of systemic methotrexate, intra-gestational sac potassium chloride (KCl) instillation, and transvaginal aspiration of the gestational sac. This report adds to the growing body of literature on safe and effective treatments for CSEP.
