发布时间:2018-10-11 07:54
【摘要】:目的探究前置胎盘合并胎盘植入的超声三维重建及MRI的影像学特点,比较其诊断的准确性。方法回顾性分析26例超声影像资料初步证实为前置胎盘,并且具有胎盘植入高风险孕妇的(孕妇年龄≥35岁,多次流产史,既往剖宫产史)[1]MRI及超声影像学资料特征。分析结果与术中情况及术后病检结果进行对照。前置胎盘植入影像学具有其特征性表现。对比分析超声三维重建及MRI对前置胎盘合并胎盘植入的诊断的准确性、敏感性、特异性。结果21个病人术后证实为胎盘植入。前置胎盘并发胎盘植入者产时、产后平均出血量为1800ml左右,明显多于未并发胎盘植入者。并发胎盘植入者子宫切除1例。MRI准确率65%(17/26),敏感性80%,,特异性20%。超声三维重建准确率81%(21/26),敏感性89%,特异性67%。两者对比无显著差异性P>0.05。结论前置胎盘伴胎盘植入高风险孕妇盘并发胎盘植入的发生率高,在终止妊娠时对母儿的生命安全威胁巨大,三维超声重建技术及MRI均能较准确的诊断胎盘植入,对手术的难度和预后的估计有较大的诊断价值。
