摘要:
【摘要】目的构建并验证儿童室间隔缺损介入封堵术后发生残余分流的预测模型,分析残余分流患儿预后情况。方法选取2017年1月至2023年3月遵义市第一人民医院及重庆医科大学附属儿童医院收治的室间隔缺损患儿178例,按照8∶2随机分为训练集144例和验证集34例,均行介入封堵术,术后随访12个月内残余分流发生情况。分析儿童室间隔缺损介入封堵术后发生残余分流的影响因素。建立儿童室间隔缺损介入封堵术后残余分流发生的预测模型,并进行模型的验证及效能评估。统计残余分流发生患儿预后情况。 结果训练集144例患儿中,21例(14.58%)介入封堵术后发生残余分流;验证集34例患儿中,5例(14.71%)发生残余分流。logistic回归分析显示,室间隔缺损基底部大小(OR=5.339,95%CI:2.197~12.975)、缺损处压差(OR=4.384,95%CI:1.804~10.655)、封堵器直径(OR=4.707,95%CI:1.937~11.439)是儿童室间隔缺损介入封堵术后残余分流发生的影响因素(P<0.05)。以上述影响因素作为预测变量建立列线图预测模型,模型验证结果显示C-index指数为0.808(95%CI:0.761~0.839),预测儿童室间隔缺损介入封堵术后残余分流发生的校正曲线趋近于理想曲线(P>0.05)。训练集ROC曲线结果显示,列线图模型预测儿童室间隔缺损介入封堵术后残余分流发生的灵敏度80.95%,特异度为84.55%,AUC为0.855(95%CI:0.774~0.937)。验证集ROC曲线结果显示,列线图模型预测儿童室间隔缺损介入封堵术后残余分流发生的灵敏度80.00%,特异度为86.21%,AUC为0.871(95%CI:0.791~0.943)。训练集21例发生残余分流患儿,有14例(66.67%)出现残余分流自愈,残余分流自愈组残余分流>4 mm的占比低于残余分流未自愈组(P<0.05)。结论室间隔缺损基底部大小、缺损处压差、封堵器直径是儿童室间隔缺损介入封堵术后残余分流发生的影响因素,基于此构建的预测模型预测儿童室间隔缺损介入封堵术后残余分流发生效能良好,残余分流<4 mm的患儿多可自行愈合。
