【摘要】：目的对比分析肺静脉畸形引流(APVC)胎儿与正常胎儿心房大小的不同,探讨胎儿期心房大小改变对APVC的诊断价值。方法对81例孕期经超声检查诊断为APVC的胎儿心脏特点进行总结,建立1 500例正常胎儿心房左右径z-score模型,比较两组心房大小的差异。结果 81例APVC中完全型68例,部分型13例;正常胎儿与APVC胎儿左房(LA)z-score差异有统计学意义(P0.05),TAPVC胎儿LA z-score均值明显小于正常胎儿(P0.001),TAPVC胎儿中61.82%LA z-score-2,PAPVC胎儿中41.67%LA z-score-2,与正常组相比差异具有统计学意义(P0.001)。结论胎儿心房大小的特征性改变是诊断APVC的重要指标之一,特别是LA z-score-2时对诊断TAPVC具有较大的参考价值。
[Abstract]:Objective to compare and analyze the difference of atrial size between fetuses with anomalous pulmonary venous drainage (APVC) and normal fetuses, and to explore the diagnostic value of atrial size change in fetal stage for APVC. Methods the characteristics of fetal heart in 81 cases with APVC diagnosed by ultrasound during pregnancy were summarized, and 1 500 normal fetal atrial left and right diameter (z-score) models were established, and the difference of atrial size between the two groups was compared. Results there were 68 cases of complete type and 13 cases of partial type in 81 cases of APVC. There was significant difference between normal fetus and APVC fetus. The mean value of LA z-score in normal fetus and APVC fetus was significantly lower than that in 61.82%LA z-score-2pAPVC fetus and 41.67%LA z-score-2in 61.82%LA z-score-2pAPVC fetus, which was significantly lower than that in normal fetal group (P 0.001). Conclusion the characteristic change of fetal atrial size is one of the important indexes in the diagnosis of APVC, especially LA z-score-2 has great reference value in the diagnosis of TAPVC.
