超声心动图检测12-14孕周胎儿三尖瓣反流的临床意义

Clinical significance of perinatal Doppler Ehocardlogram for the diagnosis of fetal tricuspid regurgitation at 12~14 week of gestation

目的探讨超声心动图检测孕12-14周胎儿三尖瓣反流的可行性及其临床意义。方法对614例孕12-14周高危孕妇的胎儿超声心动图检查结果进行分析,对早期三尖瓣反流的检出率、三尖瓣反流情况及相关原因进行探讨。结果共检出三尖瓣反流68例,检出率为11%,胎儿水肿、先天性心脏病、心律失常、宫内窘迫、孕妇糖尿病是胎儿早期中～重度三尖瓣的常见原因。结论超声心动图能检测孕早期胎儿三尖瓣反流,分析反流原因,评估预后,有重要的临床应用价值。

Objective： To assess the clinical significance of doppler ehocardlogram for the diagnosis of fetal tricuspid regurgitation（TR）at 12-14week of gestation.Methods： 614 cases of fetal cardiac of risk perinatal were examined by doppler ehocardlogram,to analysis the detection rate of TR at 12-14 week of gestation and assess the reason.Results： 68 cases of TR were detected at 12-14week of gestation.detection rate is 11%.common reasons of midrange or heavy TR at 12-14 week of gestation was hydropos fetalis;congenital heart disease;arrhythmia;fetal distress in uterus and diabetes mellitus of pregnant women.Conclusion： echocardio-gram has clinic applied value in the high risk gravida in discovering the TR at late frist and the early second trimester.
