Analysis of a clinical case on hysterocyesis combining with caesareanscar pregnancy after in vitro fertilization-embryo transfer

Aim: To explore safe and effective therapeutic strategies for hysterocyesis concurrency of caesarean scar pregnancy (CSP) that will be able to remedy the foetus within uterus.Study design: Repeated ultrasound scans confirmed hysterocyesis concurrency of CSP in a patient that conceived by in vitro fertilization-embryo transfer (IVF-ET) in our department on the 35 th day of embryo transfer.After being fully informed and signing consent, selective embryo reduction that implanted on the caesarean scar by needle aspiration of the embryo via transvaginal ultrasonography was performed.Transvaginal ultrasonography reexamination was performed on 7 th day after operation.Anti-miscarriage treatments and regular obstetric check-up ensued.Results: Emergency caesarean section was operated on 38 th week of gestation and a live infant was delivered and appeared developmentally normal.There was no heavy intraoperative haemorrhage and metrorrhexis symptom observed in the operation.Mater and infant were doing well.Conclusion: Hysterocyesis complicated CSP after IVF-ET is extremely rare.After early diagnosis, ultrasonic inducing needle aspiration of the embryo implanted on the caesarean scar can terminate CSP while hysterocyesis is effectively saving.This treatment can receive a satisfactory clinical outcome.
