Concomitant ultrasound-guided intra-gestational sac methotrexate-potassium chloride and systemic methotrexate injection in the recurrent cesarean scar pregnancy.

Recurrent ectopic pregnancy of cesarean scar is very rare and its therapeutic management is still not established. We reported the first case of recurrent cesarean scar pregnancy that was successfully treated with concomitant intra-gestational sac methotrexate-potassium chloride injection and systemic methotrexate injection. This case study provides physicians with a safe and effective minimally invasive treatment option for recurrent cesarean scar pregnancy.
