Successful management of heterotopic cesarean scar pregnancy combined with intrauterine pregnancy after in vitro fertilization-embryo transfer

Objective: To present a case of cesarean scar pregnancy combined with intrauterine pregnancy after IVF-embryo transfer. Successful embryo reduction was performed and preserved the normal intrauterine gestation. Design: Case report. Setting: Tertiary referral case center. Patient(s): A woman with cesarean scar pregnancy combined with intrauterine pregnancy after IVF-embryo transfer. Intervention(s): Early diagnosis of heterotopic cesarean scar pregnancy and selective embryo reduction was performed by ultrasound-guided potassium chloride (KCl) directed injection. Main Outcome Measure(s): Successful pregnancy outcome. Result(s): A 38-year-old woman achieve pregnancy by IVF-embryo transfer. Heterotopic cesarean scar pregnancy was diagnosed at 7 weeks gestational age. A transvaginal ultrasound-guided KCl injection was given to terminate the cesarean scar embryo and a healthy infant was delivered 6 months later. Conclusion(s): Heterotopic cesarean scar pregnancy after IVF is extremely rare. Transvaginal intracardiac injection of KCl is a safe and reliable method to terminate the cesarean scar pregnancy. Satisfactory pregnancy outcome should be achieved.
