目的：探究高危妊娠胎盘的循环变化及其与最终妊娠结局间的关系。方法：2012年9月-2013年9月收治妊娠孕妇117例，依照其脐血流S/D值及临床表现将其分为A、B、C 3组，每组39例。A组为S/D值≥95th%，主要特点为胎盘供血不足。B组为S/D值＜95th%孕妇，且存在妊娠合并症。C组为正常妊娠孕妇。对3组孕妇进行相关各项指标的检查，如胎盘内绒毛动脉阻力、绒毛血管数等，并将其与最终妊娠结局相对比。结果：A组孕妇的绒毛血管数明显比其他两组要低，而绒毛动脉S/D值则高于其他两组。B组孕妇的绒毛血管数要明显低于C组，绒毛动脉S/D值则较高。在3组孕妇中，妊娠结局最差为A组，其次为B组，C组孕妇最好。结论：运用彩色和能量多普勒超声的检查方式能够对孕妇胎盘绒毛状况进行严密监测，观察研究其血流动力学变化，为有效避免高危妊娠胎盘循环状况的发生提供帮助。

Objective:To explore the change of the circulation of high-risk pregnancy placenta and its relationship with pregnancy outcome.Methods:117 cases of pregnant women were selected from September 2012 to September 2013.According to the S/D value of umbilical blood flow and clinical manifestations,they were divided into A,B,C group,and each group had 39 patients.The S/D value of patients in the A group was not less than 95th%,the main characteristic was placental insufficiency.The S/D value of patients in the B group was less than 95th%,and there were complicated with pregnancy and complications.C group was the normal pregnant women.Three groups of pregnant women were given the examination,such as within the placenta villous arterial resistance,villous vascular number and so on,and it was compared with the final outcome of pregnancy.Results:In the A group,villous vascular number of pregnant women was significantly lower than the other two groups,and the villous arterial S/D value was higher than the other two groups.In B group,villous vascular number of pregnant women was lower than that in C group, villous arterial S/D value was high.In three pregnant women,pregnancy outcome of A group was the poorest,followed by the B group,C group of pregnant women was the best.Conclusion:The use of color and power doppler ultrasound examination method can closely monitor the placental villus status of pregnant women,observe hemodynamic changes,and provide help to effectively avoid the occurrence of high risk pregnancy placental circulation condition.
