摘要 目的探讨早孕期超声检查对单脐动脉(SUA)的诊断价值,分析SUA与胎儿结构畸形、染色体异常的相关性。方法回顾性分析2019年7月至2022年6月于福建省妇幼保健院行早孕期超声检查且为SUA的181例胎儿的临床资料,分析其合并结构畸形、染色体异常的情况并追踪其妊娠结局,探讨早孕期超声诊断SUA的价值。结果181例SUA胎儿中,孤立性单脐动脉(iSUA)占51.93%(94/181),非孤立性单脐动脉(niSUA)占48.07%(87/181)。niSUA中合并其他软指标异常及结构畸形占56.32%(49/87),仅合并其他软指标异常占35.63%(31/87),仅合并结构畸形占8.05%(7/87)。iSUA染色体异常率为9.43%(5/53),niSUA染色体异常率为25.53%(12/47),iSUA组活产率为90.43%,niSUA组活产率为34.48%,差异有统计学意义(P<0.001)。早孕期超声诊断SUA的特异性、灵敏性、阳性预测值、阴性预测值分别为99.96%、75.14%、90.67%、99.86%.结论早孕期超声对胎儿SUA诊断有较大的应用价值。SUA与胎儿结构畸形、染色体异常有一定的关系,iSUA染色体异常发生率较niSUA低。孤立性SUA预后较好,合并严重结构畸形或染色体异常时预后不良。
