摘要
We describe the transvaginal sonographic findings in a patient with complete placenta previa and increased risk of preterm birth owing to a prior history of mid-trimester pregnancy loss in whom we observed a short cervix and prolapse of the placenta and fetal membranes into the endocervical canal. We believe that this could lead to antepartum hemorrhage and mandate close observation when diagnosed. We introduced the term placental prolapse to describe our finding.
