Abstract

Abstract:

Abstract: The ultrasound evaluation of the placenta should include morphology and function. The abnormalities of placental location and structure include placenta previa, vasa previa, placenta accreta/increta/percreta, placenta abruption ,etc. The assessment of umbilical blood flow provides information on blood perfusion of the fetal-placental unit. Uterine artery Doppler is a useful test in predicting pregnancies at high risk of developing complications related to uteroplacental insufficiency.

Key words: ultrasound, umbilical artery, uterine artery

摘要：

超声评价胎盘包括胎盘的结构及功能。位置结构异常包括前置胎盘、血管前置、胎盘植入、胎盘早剥等。脐血流反映胎儿胎盘灌注，子宫动脉对于预测与子宫胎盘功能不良的妊娠并发症有一定的价值。
