摘要: |
胎儿生长受限(fetal growth restriction,FGR)可能增加胎儿和新生儿死亡风险,与新生儿并发症、儿童期认知发育迟缓和成年期疾病紧密相关。FGR的病因主要包括母体、胎儿和胎盘因素三个方面,其中胎盘因素是导致FGR的最主要原因。胎盘早期发育异常如螺旋动脉转化不良导致的母体血管灌注不良(Maternal vascular malperfusion, MVM)是导致FGR的最常见胎盘原因。此外,一些特殊的胎盘疾病,如胎盘绒毛膜板下出血(Breus’ mole)、胎盘间叶发育不良常会并发胎儿结构畸形和FGR,三倍体胎儿也常同时合并FGR及胎盘异常改变。产前结合胎盘的超声表现有助于明确FGR的病因,对FGR的产前处理有重要意义,本文针对上述多种FGR相关的胎盘异常的超声特征进行综述。 |

Abstract: |
Fetal growth restriction (FGR) are is associated with increased fetal and neonatal morbidity and mortality, recognition disorders in childhood, and some diseases of adults. The etiology of FGR includes maternal, fetal and placental factorsaspects, and placental one disorders areis the main causes of FGR. The most common placental factor related to FGR is maternal vascular malperfusion (MVM), which is caused by transformation defects of spiral arteries in the first trimester. In addition, some rare placental disorders, such as subchorionic hematoma(Breus’ mole), placental mesenchymal dysplasia and triploidy are also associated with FGR. Prenatal detection of placental anomalies can assist in clarifying the etiology of FGR, and is of great significance in to appropriate antenatal management. The aim of his paperthis review is to review describe ultrasound features of placental disorders associated with FGR. |
