Surgical technique for fertility preservation for placenta accreta spectrum without previa: Tourniquet, uterus inversion and placental dissection procedure.

The placenta accreta spectrum without previa is difficult to diagnose before delivery and sometimes requires hysterectomy. A fertility preservation procedure is useful when placenta accreta spectrum is unexpectedly encountered. A 38-year-old woman, conceived by in vitro fertilization (IVF), was not diagnosed of placenta accreta spectrum until delivery. A cesarean section was performed for fetal breech presentation. The placenta could not be detached from the uterine fundus and marked bleeding started. We conducted the "TURIP" procedure: ensured hemostasis with tourniquet of uterine isthmus, uterus inversion to expose the adhesion site with intra-venous nitroglycerin administration, placental detachment by sharp dissection under direct visualization. The detached areas were sutured for hemostasis. The patient recovered uneventfully and achieved the second pregnancy by IVF 1 year later. The TURIP procedure is useful to preserve fertility in unpredicted placenta accreta spectrum without previa, even in undiagnosed cases before delivery.
