The placentas of 14 growth-retarded fetuses with abnormal umbilical artery velocimetry and 15 appropriately grown fetuses with normal waveforms were collected immediately after delivery and analyzed in a blinded fashion. A large percentage of the arterial vessels in the placentas from the former group showed abnormal changes in the vessel wall. The percentage of abnormal arterial vessels in all placentas correlated significantly with the resistance index. This study provides an anatomical basis for the elevated resistance to blood flow in placentas from growth-retarded fetuses.
对14例脐动脉血流速度测定异常的生长受限胎儿及15例波形正常的发育正常胎儿的胎盘，在分娩后立即采集，并采用盲法进行分析。前一组胎儿胎盘的大部分动脉血管显示出血管壁的异常变化。所有胎盘中异常动脉血管的百分比与阻力指数显著相关。本研究为生长受限胎儿胎盘血流阻力升高提供了解剖学依据。
