Ultrasound diagnosis of placental abruption 33 cases report / 中华围产医学杂志

ABSTRACT

Objective To improve the antenatal diagnosis of placental abruption by ultrasound. Methods A retrospective analysis was conducted on 33 placental abruption cases in our hospital between Jan. 1988 and Apr.2003. Results Among 33 cases, 28(84 8%) were found by ultrasound. There were more cases with anterior placental and severe abruption than posterior placenta and mild abruption without symptoms. The sonographic characteristics of placental abruption was dark and low echo area between placenta and uterine wall. Among these cases, mild and mixed echos were detected in 15 cases, partial thickened placenta 6 cases, protruding masses at the edge of placenta or under chorionic plate 8 cases(one case was misdiagnosed as chorioangioma). No signals of blood flow was shown the abruption area of placenta by color Doppler flow image. Conclusion Antenatal sonography has an important role in diagnosing placental abruption.
