[Cesarean scar pregnancy].

Background: A rare, but potentially life-threatening complication of a Cesarean section is a so-called Cesarean scar pregnancy (CSP). This concerns an ectopic pregnancy, where the implantation takes place in a niche of the Cesarean section scar.

Case Description: We describe the case of a 29-year-old pregnant woman (G5P3), who after a amenorrhoea period of 6 weeks was referred to us by a midwife because the sonography showed an empty uterus. She had previously undergone two Cesarean sections. During transvaginal sonography we observed a small amiotic sac in the Cesarean section scar, lacking a clear heart rhythm.

Conclusion: Since there are no general guidelines for the treatment of CSP, a patient-specific approach should be taken to determine optimal management. There is, however, a clear preference to terminate the pregnancy as soon as possible.
