摘要
目的探讨彩色多普勒超声检测孕12—14周胎儿三尖瓣反流的临床价值。方法52例孕12-14周发现三尖瓣反流的胎儿为反流组，根据反流程度分为轻度反流和中重度反流；50例孕12-14周未见三尖瓣反流的胎儿为对照组。两组均于孕中晚期行彩色多普勒系统畸形筛查。结果反流组胎儿轻度反流46例，中重度反流6例；检出胎儿异常10例，检出率为19．2％。对照组检出胎儿异常2例，检出率为4．0％；反流组胎儿异常检出率高于对照组（P〈0．05）。结论孕12-14周三尖瓣反流的胎儿发生异常的风险高于正常胎儿，彩色多普勒超声检测孕早期胎儿三尖瓣反流有重要的临床价值。
Objective To explore clinic value of color Doppler ultrasound in detecting the fetal tricuspid regurgitation （TR） at 12-14th week of gestation. Methods Fifty-two fetals with TR at 12-14th week of gestation were divided into mild reflux group, moderate and severe reflux group. Fifty fetuses without TR at 12-14th week of gestation were used as the control group. Fetals in the two groups were examined by color Doppler ultrasound to screen abnormalities during the second or third trimester. Results Forty-six cases were mild reflux and 6 cases were moderate and severe reflux. Ten cases in TR group were examined as fetal abnormalities, and the detection rate was 19.2%. Two cases in control group were examined as fetal abnormalities, and the detection rate was 4.0%. The detection rate in TR group was higher than that in control group （P 〈 0.05 ）. Conclusion Fetuses with TR at 12-14th week of gestation has higher risk than normal fetuses. Color Doppler ultrasound has important clinical value in detecting TR in the first trimester.
