摘　　要：目的 与病理结果对照，探讨正常妊娠胎盘内绒毛血管树的三维能量多普勒超声显像特征。方法 用三维能量多普勒超声显示20～39周32例正常单胎妊娠胎盘内绒毛血管树分支。分娩结束后，对娩出的胎盘，用电子显微镜观察胎盘内绒毛血管树分支结构。结果 三维能量多普勒超声显示的胎盘内绒毛血管树状结构与病理结构基本一致。三维能量多普勒超声对初级绒毛血管、次级绒毛血管和三级绒毛血管的显示率分别为100％、100％和90％。对绒毛小叶血管未能显示。结论 三维能量多普勒超声可以显示胎盘内绒毛血管树分支结构。未来可用于对高危妊娠胎盘血管结构与功能的评价。Objective To compare the pedonnancc of three-dimensional color power angiograpby with pathology in the visualization of intraplacental vessel trees. Methods Total 32 normal singleton pregnant women with 20- 39 weeks gestation were examined with 3-D color power angiography to observe the branches of the intraplacental villous vascular trees, which were observed with electron micrographs after dilivery. Rusults The branches of the intraplacental villous vascular trees observed by 3-D color power angiograpby were the same as the pathology. The presentation rate of the first, second and third stem villous vessels by 3-D color power angiography was 100% and 100% and 90%. There was no visualization of the small villous vessels. Conclusion The intraplacental villous vessels could be visualized on 3-D color power angiograpby, which may be used to evaluate the placental function of high-risk pregnancy.
