Description
Summary:Our study attempted to identify whether sonographic markers for placenta accreta may be present as early as the first trimester. We reviewed 10 cases with pathologically proven accreta and retrospectively analyzed their first‐trimester images. The gestational ages ranged from 8 weeks 4 days to 14 weeks 2 days. Sonographic findings included anechoic placental areas (9 of 10), low implantation of the gestational sac (9 of 10), an irregular placental‐myometrial interface (9 of 10), and placenta previa (7 of 10). Nine patients had at least 1 prior cesarean delivery; 3 had additional uterine surgical procedures. One patient underwent hysteroscopic myomectomy. Our case series suggests that signs of placenta accreta may be present in the first trimester.
