补充资料：前置胎盘的超声所见
前置胎盘的超声所见
胎盘的位置低于胎先露部，称为前置胎盘。采用超声检查前置胎盘准确率很高，目前几乎代替了阴道检查和X线检查。检查前要求孕妇适当的充盈膀胱，目的是观察胎盘下缘与子宫内口之间的关系。探头采用纵、横、斜切联合使用，其中正中纵切很重要。由于在妊娠中期对胎盘位置随着妊娠周数增加，子宫下段形成而会向上移动，故诊断前置胎盘应在孕28周以后，至于超声所见胎盘位置以诊断前置胎盘的不同类型与临床分类同，即中央性前置胎盘：子宫内口均被胎盘完全覆盖；部分性前置胎盘：胎盘下缘部分覆盖子宫内口；边缘性前置胎盘：胎盘下缘抵子宫内口边缘。低置胎盘：胎盘部分分布于子宫下段，但尚未到达宫颈内口。
