摘要
目的:探讨应用三维彩色能量多普勒超声成像(three-dimensional color power angiographic,3D-CPA)技术定量评价正常妊娠不同孕周胎盘血流情况的价值。方法:选取100例正常孕妇,分为A组(孕周24+1～28周),B组(孕周28+1～32周),C组(孕周32+1～38周),对所有孕妇胎盘床血管进行三维重建,采用VOCAL软件测量VI、FI及VFI并观察其变化,并与孕龄(gestational age,GA)进行比较,计算它们之间的相关关系。结果:B组及C组较A组可显示较多的绒毛干血管。各组的VI、FI、VFI值分别为:A组4.01±1.50、31.5±2.88、1.67±0.62;B组5.94±0.91、34.7±3.21、2.09±0.77;C组6.23±2.11、36.9±4.78、2.35±0.90。3组VI、FI、VFI值的比较:B组及C组较A组均升高且差别有统计学意义(P<0.05)。B组较C组间差别均无统计学意义(P>0.05)。结论:3D-CPA技术使定量评估胎盘血流灌注成为可能,是观察孕妇的胎盘血流灌注变化的有效工具。
Objective：To investigate the value of three-dimensional color power angiographic （3D-CPA） on assessment of placental function in normal pregnancy with different gestational age. Methods： A total of 100 normal pregnant women were divided into group A （gestational age between 24＋1 -28 weeks）, group B （gestational age between 28＋1 -32 weeks）, and group C （gestational age between 32＋1 -38 weeks）. VI, FI and VFI were detected by 3D-CPA in each group, and the relationship between VI, FI and VFI and the gestational age was determined. Results： More stem villous vessels were presented in groups B and C than in groupA. VI, FIandVFIwere4.01±1. 50, 31.5±2.88 and 1.67±0.62 in groupA; 5.94±0.91, 34.7 ±3.21 and 2.09±0.77 in group B; and 6.23±2.11, 36.9±4.78 and 2.35±0.90 in group C; respectively. The three-dimensional Doppler indices in groups B and C were significantly higher than those in group A （ P 〈0.05）. There were no significant differences in the three-dimensional Doppler indices between groups B and C （ P 〈0.05）. Conclusion： Three-dimensional color power angiographic make the quantitative evaluation of placental function to be possible, and it is an appropriate tool for routine evaluation ofplacental function.
