目的：通过超声测量分析孕20～26周胎盘血池大小及其对胎儿脐静脉血流量的影响。方法180例孕20～26周正常单胎，按有无血池及血池体积是否大于20 cm3分为正常组、小血池组、大血池组，分别测量胎儿脐静脉血流量、左门静脉分流率等指标，并进行方差分析。结果大血池组各指标与正常组、小血池组比较差异有统计学意义（P＜0.05），小血池组各指标与正常组比较差异无统计学意义（P＞0.05）。结论孕20~26周，体积大于20 cm3的胎盘血池能够影响胎儿的脐静脉循环。

ObjectiveTo investigate the impacts of placental lakes on fetal umbilical vein blood flow at 20-26 weeks of gestation by Doppler ultrasound.Methods 180 fetuses from uncomplicated singleton pregnancies at 20-26 weeks of gestation were divided into three groups based on the size of the placental lakes: normal group (no placental lakes), small group (the volume of placental lakes≤20 cm3), and large group (the volume of placental lakes >20 cm3). The umbilical vein blood flow (QUV), left portal vein blood flow (QLPV), and QLPV/QUV of the three groups were measured respectively by Doppler ultrasound. The variance analysis was done.Results There was a significant difference in indicators between the large group and the normal, small group (P<0.05). There was no significant difference in indicators between the small group and the normal group (P>0.05).Conclusion The placental lakes whose volume are greater than 20 cm3can affect fetal umbilical venous circulation at 20-26 weeks of gestation.
