摘要
Placenta previa is the main cause of bleeding throughout pregnancy,and it is associated with serious complications,such as infection,that lead to a poor prognosis.Gynecological sonography is recommended as the first-line examination technique for the surveillance and determination of vaginal bleeding and for early intervention.We report the case of a patient with gradually expanded hypoechoic lesion and extremely high serumα-fetoprotein level during her third trimester,and discuss their potential relationship in evaluating the progression of placental necrosis.
