摘要 目的探究节段分析法产前超声心动图联合时间-空间关联成像(STIC)检查在胎儿心脏畸形筛查中的应用效果。方法选取2022年1月~2023年12月在广东医科大学顺德妇女儿童医院进行产前超声检查怀疑胎儿心脏畸形的80例孕妇作为研究对象。所有孕妇均接受超声心动图检查,首先运用节段分析法明确诊断,随后联合STIC技术再次进行检查。以新生儿病理诊断和尸检结果为金标准,比较节段分析法产前超声心动图检查、节段分析法产前超声心动图联合STIC检查与金标准的诊断一致性,以及对胎儿心脏畸形的诊断效能。结果节段分析法产前超声心动图检查对胎儿心脏畸形的诊断一致性优,Kappa值为0.667(P<0.05);节段分析法产前超声心动图联合STIC检查对胎儿心脏畸形的诊断一致性非常优秀,Kappa值为0.898(P<0.05)。尽管与金标准相比,节段分析法产前超声心动图检查和节段分析法产前超声心动图联合STIC检查在诊断胎儿心脏畸形的灵敏度、特异度、阳性预测值、阴性预测值方面差异无统计学意义(P>0.05),但节段分析法产前超声心动图联合STIC检查的诊断准确度(96.25%)显著高于节段分析法产前超声心动图检查(87.50%),差异具有统计学意义(P<0.05)。结论节段分析法产前超声心动图联合STIC检查在胎儿心脏畸形筛查和畸形类型诊断中的应用效果较为理想,显著提升了诊断准确度。
