摘　　要：胎盘功能异常是子痫前期和胎儿生长受限发病的主要原因之一,会导致子宫动脉阻力增高,绒毛发育异常等,造成母婴不良结局,故对子宫螺旋动脉及胎盘绒毛血流的量化评估是目前亟待解决的问题。超微血流成像作为一项新兴的彩色多普勒超声技术,能够有效消除运动伪像,清晰显示低速血流和微小血管结构,弥补了传统彩色多普勒超声技术的不足,适用于对绒毛小动脉及子宫螺旋动脉成像,通过观察血管形态、数量及测量相关血流动力学参数评估胎盘血流灌注情况。本文就超微血流成像在胎盘血流灌注评估中的应用进展进行综述。Abnormal placental function is one of the primary causes of preeclampsia and fetal growth restriction,leading to increased uterine artery resistance,abnormal villous development,and adverse maternal and fetal outcomes.Therefore,the quantitative assessment of uterine spiral artery and placental villous blood flow is an urgent issue to be addressed.Superb microvascular imaging(SMI),as a new color Doppler ultrasound technology,which can effectively eliminate motion artifacts,clearly display low-velocity blood flow and microvascular structures,overcoming the limitations of traditional color Doppler ultrasound technology.It is suitable for imaging small villous artery and uterine spiral artery,allowing the evaluation of placental blood flow perfusion by observing vascular morphology,quantity,and measuring relevant hemodynamic parameters.This article reviews the application progress of SMI for assessing placental blood flow perfusion.
