【摘要】：目的探讨二维超声诊断胎儿主动脉缩窄(COA)的直接和间接指标的应用价值。方法回顾性分析经胎儿超声心动图检查诊断、并经出生后或尸体检查证实为COA的中孕期胎儿18胎。以主动脉峡部Z分数(Z-AoI)-2、主动脉峡部内径(AoId)≤2.0 mm、主肺动脉内径/升主动脉内径(MPAd/AAOd)≥1.6、二尖瓣环横径/三尖瓣环横径(MVd/TVd)0.6为诊断标准,分别分析其诊断符合率,同时测量主动脉瓣环内径(AOd),计算中孕期COA胎儿AOd的参考范围。结果在18胎COA胎儿中,Z-AoI、AoId、MPAd/AAOd、MVd/TVd的诊断符合率分别为94.44%(17/18)、61.11%(11/18)、66.67%(12/18)、44.44%(8/18),差异有统计学意义(P0.05)。COA胎儿AOd的参考范围为2.60~2.98mm。结论 Z-AoI诊断COA的符合率最高;中孕期COA胎儿AOd为2.60~2.98mm。
