摘要
目的探讨彩色多普勒在中晚孕胎儿三尖瓣反流产前筛查中的临床意义及鉴别诊断。方法选择2009年3月-2012年6月就诊的11265例中晚期孕妇。观察其胎儿三尖瓣口彩色多普勒反流情况及脉冲多普勒评估流速、压差，追踪随访。结果1306例胎儿监测到三尖瓣反流，发生率11．6％。其中反流速度大于2．8m／s者46例，小于2．8m／s者1261例。结论彩色多普勒能够敏感地检出胎儿三尖瓣反流，对胎儿某些心脏疾病的诊断提供重要临床价值。
Objective To investigate the clinical significance and differential diagnosis of color doppler in the prenatal screening of middle and late pregnancy fetal tricuspid regurgitation. Methods 11265 middle and late pregnancy gravidae treated from March 2009 to June 2012 were selected. The color doppler tricuspid regurgitation situation of their fetuses was observed and the pulse doppler was used to evaluate the flow rate and pressure difference; the fetuses received follow-up visits. Results 1306 fetuses showed tricuspid regurgitation, with the incidence of 11.6%.Among them, 46 fetuses had a backflow rate over 2.8m/s and 1261 fetuses less than 2.8m/s. Conclusion Color doppler can detect fetal tricuspid regurgitation sensitively and is therefore of important clinical value for some fetal heart diseases.
