The transverse fundal uterine incision (TFUI), a new cesarean section technique, is effective in cases of abnormal placentation which may cause massive hemorrhage. A 43-year-old multipara woman underwent TFUI cesarean section after being diagnosed with placenta previa. One year and 4 months later, she conceived naturally. The placenta was located on the previous cesarean section scar, and placenta percreta was suspected on magnetic resonance imaging. At 35 weeks and 2 days of gestation, cesarean delivery was performed. After a decision was made not to remove the placenta, total hysterectomy was performed, and bleeding was successfully controlled. Histopathological analysis of the uterus revealed placenta accreta. Although TFUI is a useful cesarean section method, the risk of placenta accreta may increase in the next pregnancy, requiring careful perinatal management.
