目的 探讨儿童先天性冠状动脉肺动脉瘘患者的超声心动图特征.方法 回顾分析25例手术或冠状动脉造影或CT检查确诊为先天性冠状动脉肺动脉瘘儿童患者的临床及超声心动图资料,总结其声像图特征.结果 25例冠状动脉肺动脉瘘患者,手术证实21例,冠状动脉造影证实2例,心脏CT证实2例.合并发绀型先心病患者5例,超声心动图均可表现出典型征象,13例经超声心动图提示存在冠状动脉肺动脉瘘患者,肺动脉内均可见细小血流束.6例漏诊患者术中证实存在细小冠状动脉肺动脉瘘.结论 超声心动图对合并发绀型先心病患者可明确诊断,对细小冠状动脉肺动脉瘘患者可通过肺动脉内异常血流束提示诊断.“,”Objective To investigate echocardiographic feature in diagnosis of coronary-to-pulmonary fistula in children.Methods 25 cases with coronary to-pulmonary fistula confirmed by surgery/coronary angiography/CT scan underwent ultrasonography.We reviewed and analysed all data of patients.Results 21 of 25 patients were validated by surgery,2 cases were validated by coronary angiography and 2 cases were validated by CT scan.5 cases of coronary=to-pulmonary fistula with cyanosis congenital heart disease were diagnosed by typical signs.13 cases had abnormal pulmonary blood flow which indicated the existence of fine fistula.Very fine fistula confirmed by surgery in 6 cases was omitted.Conclusions Echocardiography could diagnose coronary-to-pulmonary fistula with cyanosis congenital heart disease and provide information of pulmonary blood flow in diagnosing of fine coronary to-pulmonary fistula.
