完全性前置胎盘伴胎盘巨大血窦1例

One case of complete placenta previa with huge placental sinusoid

完全性前置胎盘是指胎盘组织完全覆盖在宫颈内口,可导致产后出血甚至危及孕产妇生命安全,是一种严重的妊娠并发症。胎盘血窦是指胎盘内被正常回声的胎盘组织所包围的单个或多个形状不规则的回声(可为无回声、低回声或混合回声),为均匀的、无绒毛的空间,但其发病机制以及可导致的不良妊娠结局尚存在争议。本文报道1例完全性前置胎盘伴胎盘巨大血窦疾病,以期可以重视孕期随访,警惕不良妊娠结局的发生,更好地改善母婴结局。

Complete placenta praevia is a serious complication of pregnancy in which the placental tissue completely covers the endocervix and can lead to postpartum hemorrhage or even endanger maternal life.Placental sinusoids are single or multiple irregularly shaped echoes(which can be anechoic,hypoechoic,or mixed)surrounded by normal echogenic placental tissue in the placenta,but their pathogenesis and the adverse pregnancy outcomes are still controversial.This paper reports a case of complete placenta previa with huge placental sinusoid,with the aim of improving maternal and infant outcomes by paying attention to the follow-up during pregnancy and being alert to the occurrence of adverse pregnancy outcomes.
