A case of placenta previa and placenta increta undergoing uterine sparing surgery

Obstetric risks are increased in pregnancies following previous cesarean section deliveries. Placenta increta and placenta previa pregnancies are two important clinical manifestations of abnormal placentation entities. Placenta accreta occurs in 5-10% of pregnancies complicated by placenta previa. The most important risk factor for placenta accreta is a history of uterine surgery. A thin, defectively formed or absent decidua basalis layer cannot show resistance to deep penetration of trophoblasts and placenta invades this pathological region of uterus that has previously been traumatised by uterine surgery. Placenta accreta is diagnosed with characteristic signs during prenatal ultrasound examination. The first clinical sign of placenta accreta is excessive and life-threatening bleeding that occurs during manual placental separation. Prenatal diagnosis is important to avoid this complication, which may lead to maternal mortality. In this case, in which an invasion anomaly was detected in preoperative ultrasonography, the treatment of the patient accompanied by placenta increta and placenta praevia with uterus-preserving surgery was discussed.
