目的:探讨超声心动图检测胎儿三尖瓣反流的临床意义。方法:应用Philips Sonos-7500彩色多普勒超声诊断仪对460例孕龄20～40周的高危孕妇行胎儿超声心动图检查,对三尖瓣反流胎儿的三尖瓣反流情况及伴发高危因素进行记录,并对三尖瓣反流胎儿进行产后随访或引产后尸检。同时检测孕龄20～40周无明显高危妊娠因素的孕妇450例,作为对照组。结果:高危组胎儿共检出三尖瓣反流59例,三尖瓣反流检出率为12.8%。对照组胎儿共检出三尖瓣反流21例,三尖瓣反流检出率为4.7%。两组胎儿三尖瓣反流检出率间差别有统计学意义(P<0.01)。结论:超声心动图能够敏感地检出胎儿三尖瓣反流。
Objective: To investigate the clinical significance of echocardiography in detecting fetal tricuspid regurgitation. Methods: Forty-six high-risk pregnant women with gestational age of 20-40 weeks were examined with echocardiography using Philips Sonos-7500 color Doppler sonography. Tricuspid regurgitation High risk factors were recorded, and postpartum follow-up of tricuspid regurgitation or fetus post-induction of autopsy. Simultaneous detection of pregnant women of gestational age 20 to 40 weeks without significant risk factors of 450 pregnant women, as a control group. Results: Totally 59 cases of tricuspid regurgitation and 12.8% of tricuspid regurgitation were detected in high-risk fetus. In the control group, 21 cases of tricuspid regurgitation and tricuspid regurgitation were detected in 4.7% of fetuses. There was a significant difference between the two groups (P <0.01). Conclusion: Echocardiography can detect fetus tricuspid regurgitation with sensitivity.
