The patient was a 26-year-old pregnant woman, gravida 5, para 2 (3 spontaneous abortions, 1 Caesarean section, 1 Caesarean section after transvaginal delivery). Although Cesarean section scarred pregnancy was previously suspected at 9 weeks of gestation in a private clinic, a final decision was not made. She subsequently underwent routine pregnancy checkups. At 19 weeks’ gestation, she was referred to our perinatal center due to oligohydramnios. Although she did not have any symptoms, ultrasound revealed that the placenta was attached on the previous Caesarean section scar. Although there were no findings of outflow of the amniotic fluid including the echo-free space in the abdominal cavity and rupture of membrane, the amniotic fluid cavity was almost absent. Since fetal morphological assessment was difficult, amniotic fluid injection was performed after admission to the hospital. Fetal assessment was then attempted, which showed a bell-shaped thorax, absence of gastric fluid, and absence of the bilateral kidneys and the bladder. Moreover, the placenta was adhered to the whole Caesarean section scar and bulged. A closed small uterine body was also found at the uterine fundus. Therefore, diagnoses of Cesarean scar pregnancy and Potter syndrome were made. Considering the risk of uterine rupture, we decided to perform induced abortion after consulting the patient and her family. Because she had a strong desire for uterine preservation, wedge resection of scarred pregnancy after Caesarean section and wound repair were performed. Conclusion: Amniotic fluid injection successfully led to a diagnosis of previous Caesarean scarred pregnancy with oligohydramnios due to Potter syndrome. This case suggests that ultrasound evaluation of the previous Caesarean scar in early pregnancy is important for safe management of the pregnancy.
