Aim Transverse uterine fundal incision (TUFI) was developed to avoid catastrophic hemorrhage associated with cesarean section of the placenta previa–accreta. Abdominal incisions extend as far as the upper abdomen in patients in the third trimester of pregnancy and require general anesthesia. Instead, we tried to aspirate amniotic fluid (AF) to reduce the uterine size. Methods TUFI was performed in 19 of our patients in the third trimester in whom placenta previa accreta could not be ruled out between June 2012 and August 2016. After the lower abdominal vertical incision, we attempted to exteriorize the uterine fundus. If this was impossible, we inserted an 18‐gauge spinal needle into the amniotic space. We aspirated AF until the uterine fundus could be exteriorized. Results We exteriorized the uterine fundus without extending the incision to the upper abdomen by aspirating 250–670 mL of AF in 12 patients who were between the 33rd and 37th week of pregnancy, and TUFI was performed under spinal anesthesia. AF aspiration was not required in four patients who were in the 30th or 31st week of pregnancy and in two patients with oligohydramnios in the 35th week of pregnancy. In one case, the trial was canceled due to hemorrhagic AF aspiration. No serious complications were observed in mothers or neonates. Conclusion TUFI could be made by abdominal incision to the left of the umbilicus under spinal anesthesia without anesthesia by reducing the uterine size through AF aspiration, even for patients in the third trimester of pregnancy.
