| 摘 要： | 目的探讨胎儿心轴异常在先心病和胸腹病变超声诊断中的意义。方法中孕期经超声检查的173例正常胎儿和54例先心病、10例胸腹病变胎儿,分为三组,在四腔心切面上进行心轴角度的测量和分析。结果正常胎儿的平均心轴角度为(41.1±8.2)°,先心病组为(51.4±18.3)°,与正常组相比有显著性差异(P<0.0001),其中左心发育不良综合征、心内膜垫缺损、右室双出口等病种合并心轴异常的比例较高。胸腹病变组平均心轴角度为(59.7±15.9)°,与正常组相比有显著性差异(P<0.001),导致心轴异常的病种主要为膈疝和腹腔内脏外翻。按超过正常胎儿99%正常值范围(20.3°～61.9°)为异常心轴统计,心轴左偏(>62°)在三组中分别为1/173(0.6%),16/54(29.6%)和1/10(10.0%);心轴右偏(<20°)在三组中分别为0,6/54(11.1%)和3/10(30.0%)。结论中孕期胎儿心轴角度的测定简单易行,当其<20°或>62°时提示可能存在心脏畸形或胸腹腔病变,应进一步检查确诊。
