目的探讨产前超声诊断胎儿心腔内强光点的临床价值。方法对2006年7月-2009年12月32 000例孕妇自孕18周开始,发现胎儿心腔内强光点作为研究对象,并进行胎儿超声心动图复查。结果 32 000例孕妇当中共发现胎儿心腔内强光点938例,伴发胎儿畸形8例,其中心脏畸形4例(3例为法洛四联症,1例为永存动脉干),另伴单脐动脉4例。结论产前超声检测胎儿心腔内强光点,直观、清晰,但对单纯无合并胎儿畸形的心腔内强光点,并没有很大的临床意义,不提倡胎儿羊水或脐血染色体检查,而对有合并症的胎儿,可进行胎儿系统超声或染色体检查。
Objective To investigate the clinical value of prenatal ultrasound in diagnosing strong light spot in fetal heart cavity. Methods From July 2006 to December 2009, 32 000 pregnant women started their pregnancy at 18 weeks and found that the bright spot of fetal heart cavity was taken as the research object and the fetal echocardiography was performed. Results A total of 938 cases of fetal intracardiac bright spot and 8 cases of fetal malformations were found in 32 000 pregnant women, including 4 cases of cardiac malformation (3 cases of tetralogy of Fallot and 1 case of perpetual survival artery) Single umbilical artery in 4 cases. Conclusion Prenatal ultrasound detection of bright spots in the fetal cardiac cavity, intuitive and clear, but the simple heart of the fetal heart rate with bright spot, and no great clinical significance, do not advocate fetal amniotic fluid or cord blood chromosome examination, For fetuses with comorbidity, fetus system ultrasound or chromosome examination.
