摘    要:
目的 探讨彩超对孕16~40周胎儿下腔静脉(IVC)血流多普勒正常参考范围的评估价值.方法 将744例单胎妊娠孕妇(孕16 ~ 40周)根据孕周进行分组,每个孕周27 ~ 35例,利用彩超测量胎儿的IVC多普勒参数,包括前负荷指数、峰值指数、搏动指数.结果 所有胎儿IVC多普勒参数在孕16~26周呈快速下降的趋势,之后则保持相对稳定或轻微下降,直到妊娠结束.结论 建立孕16 ~ 40周每个孕周的IVC血流正常多普勒参考范围,可以成为有效的、无损伤的评估胎儿心脏功能的方法.

关 键 词:胎儿  超声检查,多普勒,彩色  产前诊断  下腔静脉

Abstract:
Objective To study the estimated value on normal reference ranges of inferior vena cava (IVC) Doppler indices from gestation 16 to 40 weeks of fetus with color ultrasound.Methods Seven hundred and forty-four single birth gravida with gestation 16 to 40 weeks were grouped according to the gestational weeks with 27-35 cases each.The IVC Doppler indices were measured by color ultrasound,including preload index,peak velocity index and pulsatile index.Results All IVC Doppler indices rapidly declined from gestation 16 to 24 weeks,and they were relatively constant or slightly decreased throughout the end of pregnancy.Conclusions To set up the normal reference ranges of IVC Doppler indices for gestation from 16 to 40 weeks means a lot for every pregnant.This normative data may be a useful noninvasive tool for evaluation of fetal cardiac function.
Keywords:Fetus  Ultrasonography,Doppler,color  Prenatal diagnosis  Inferior vena cava
