超声在胎盘植入性疾病中诊断的应用

Application of ultrasound in the diagnosis of placental accretion disease

胎盘植入性疾病(Placenta Accreta Spectrum disorder,PAS)产后出血概率大,预后不佳。产前超声成像能为PAS的诊断和临床处理提供重要的诊断依据,可以帮助患者改善产前检测,从而对妊娠结局产生积极影响。本文主要对近五年的产前超声检查PAS的超声声像特征及检查方法进行综述。旨在推荐使用超声影像学技术及早关注高危因素人群,密切关注胎盘状况进行筛查,最终实现个性化保障母婴安全。

Placenta accreta spectrum disorder(Placenta accreta spectrum disorder,PAS)has a high probability of postpartum hemorrhage and a poor prognosis.Prenatal ultrasound imaging can provide an important diagnostic basis for the diagnosis and clinical management of PAS,and can help patients improve prenatal detection,so as to have a positive impact on pregnancy outcomes.The ultrasonographic characteristics and examination methods of PAS in prenatal ultrasonography in recentfive years are reviewed in this article.This is aimed to recommend the use of ultrasound imaging technology to pay early attention to high risk groups,pay close attention to the placenta status for screening,andfinally achieve personalized protection of maternal and infant safety.
