摘      要：BACKGROUND: The risk of placenta previa and accreta is increased in females wi th previous cesarean deliveries, and there has been an increasing number of thes e operations. CASES: We present 2 cases with previous cesarean and placenta prev ia in the following pregnancy. One patient had placenta accreta and the other, p lacenta percreta. In both cases, prenatal diagnosis was based on ultrasonography , where features such as loss of the hypoechoic retroplacental zone and irregula r uterine serosa were found in grayscale ultrasonography. In color Doppler imagi ng, in both cases, increased vascularity between myometrium and placenta, as wel l as intraplacental lacunae, were seen. Thinning of the uterine wall, found in m agnetic resonance imaging, contributed to the diagnosis of placenta percreta. CO NCLUSION: Prenatal diagnosis of placenta accreta is of importance because it red uces fetal and maternal morbidity as appropriate preoperative and perioperative procedures are possible.
