摘要
目的 对产前B超检查产后证实为胎盘早剥的病例进行分析 ,以提高B超对胎盘早剥的确诊率。 方法 对我院 1988年 1月至 2 0 0 3年 4月间 3 3例胎盘早剥的声像图表现及临床资料进行回顾性分析。 结果 产前B超诊断胎盘早剥符合率为 84.8% (2 8例 ) ,其中前壁胎盘及重度胎盘早剥符合率高(93 7% ,10 0 % ) ,而后壁胎盘及轻度早剥无临床症状符合率低 (72 77% ;0 )。胎盘早剥的超声图像特征为胎盘与子宫壁间为暗区、低回声 ,中等回声或混合回声 15例 ,胎盘局部增厚 6例 ,胎盘边缘或绒毛膜板下突出肿块 8例 (误为绒毛膜血管瘤 1例 )。彩色多普勤血流显像显示胎盘剥离区无血流信号。 结论 产前B超捡查对诊断胎盘早剥具有很重要的临床价值 ,为临床处理及分娩方式的选择提供了依据。
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.
