超声心动图与心血管造影在小儿单纯室间隔缺损、动脉导管未闭介入封堵治疗中的应用价值OA

Objective To explore the application value of echocardiography and cardiovascular angiography in interventional occlusion therapy of simple ventricular septal defect(VSD)and patent ductus arteriosus(PDA)in children.Methods A total of 96 children with simple VSD or PDA who underwent interventional occlusion therapy in our hospital from January 2023 to December 2025 were retrospectively enrolled,including 46 cases of VSD and 50 cases of PDA.All children underwent preoperative transthoracic echocardiography and intraoperative cardiovascular angiography.Taking intraoperative cardiovascular angiography results as the diagnostic standard,the diagnostic concordance rates of echocardiography for VSD and PDA as well as its consistency with angiography results were calculated.The differences in the VSD defect diameter and PDA narrowest diameter measured by the two methods were compared,and the conditions of interventional occlusion therapy were recorded.Results In all 96 children,preoperative echocardiography and intraoperative cardiovascular angiography successfully visualized the lesions.The diagnostic concordance rates of echocardiography for VSD and PDA were 97.83％(45/46)and 98.00％(49/50),respectively,showing excellent consistency with cardiovascular angiography(Kappa value=0.958).The VSD defect diameter and PDA narrowest diameter measured by echocardiography were both larger than those measured by cardiovascular angiography(P＜0.05).All 96 children successfully completed interventional occlusion therapy.Children with VSD had longer surgery time and X-ray exposure time than children with PDA(P＜0.05),but there were no statistically significant differences in occluder diameter,residual shunt,and incidence of complications between the two groups(P＞0.05).Conclusions Preoperative echocardiography has high accuracy in diagnosing simple VSD and PDA in children,and can be used as the preferred noninvasive imaging method for preoperative screening and preliminary judgment of lesion type before interventional occlusion therapy.Cardiovascular angiography has greater advantages in accurately measuring defect diameter and selecting the occluder type.The combined application of the two methods can provide reliable imaging evidence for interventional occlusion therapy of simple VSD and PDA in children.
