摘要
目的探讨儿童肺静脉异位连接的超声表现以及经胸超声心动图(TTE)诊断价值。方法回顾性分析经手术证实的31例肺静脉异位连接患儿,其中男22例,女9例,年龄22天～10岁,完全型肺静脉异位连接(TAPVC)18例,部分型肺静脉异位连接(PAPVC)13例。结果31例APVC在TTE中均有右心负荷增加表现。18例TAPVC的解剖分型为心上型9例(50%),心内型9例(50%),16例(88.89%)经胸超声心动图诊断与手术结果完全或基本符合,2例(11.11%)误诊为部分型房室间隔缺损。13例PAPVC的解剖分型为心内型12例(92.31%),心上型1例(7.69%),均合并房间隔缺损,其中9例(69.23%)合并静脉窦型房间隔缺损;9例(69.23%)TTE诊断与手术结果完全或基本符合,4例(30.67%)误诊为单纯房间隔缺损。结论超声心动图发现右心增大时,无论是否伴有房间隔缺损,均应注意常规检查4条肺静脉入口位置及血流方向。
Objective To assess the value of transthoracic echocardiography（TTE）in detection of anomalous pulmonary venous connection（APVC）.Methods Thirty-one children with APVC,22 males and 9 females,with the mean age of 22 days-10 years,including 18 total APVC（TAPVC）and 13 partial APVC（PAPVC）,were diagnosed with TTE and then proved by surgery.Results Dilated right ventricle and right atrium were found in all patients.There were 9 supracardiac and 9 intracardiac cases respectively in the 18 cases of TAPVC,and 16 of them（88.89%）were identified by TTE,the rest 2 were misdiagnosed as partial atrioventricular septal defect.There were 12 intracardiac and 1 supracardiac types respectively in the 13 cases of PAPVC,all complicated with atrial septal defect（ASD）,and 9 with sinus venosus ASD.Nine of the 13 cases with PAPVC（69.23%）were identified by TTE,the other 4 cases were misdiagnosed as ASD.Conclusion TTE is important to the diagnosis of APVC.For patients with dilated right heart,either complicated with ASD or not,the 4 pulmo- nary veins should be routinely explored to improve the accuracy of diagnosis for APVC.
