宫内发育迟缓(IUGR)是胎儿未能达到正常生长指标的一种综合征,是围产儿死亡的第二原因。在临床上尚缺乏有效预测其不良妊娠结局的检测方法。近年国外学者采用超声多普勒技术检测脐动脉、脑中动脉、脐静脉等的频谱图像,发现其改变与不良妊娠结局间有良好的相关性,可用以预测个体胎儿发生新生儿并发症的高危性并指导临床适当的干预处理。 Intrauterine growth retardation (IUGR) is a syndrome of fetal failure to achieve normal growth and is the second cause of perinatal death. There is a lack of clinically effective methods for predicting adverse pregnancy outcomes. In recent years, foreign scholars using ultrasound Doppler detection of umbilical artery, middle cerebral artery, umbilical vein and other spectral images and found that changes and adverse pregnancy outcomes have a good correlation can be used to predict individual fetus neonates with high risk of complications Sex and guide the appropriate clinical intervention.
