混合型完全性肺静脉异位引流的CT及MRI诊断

摘要

Objective To investigate the value of CT and MRI in diagnosis of mixed total anomalous pulmonary venous connection.Methods We retrospectively reviewed 26 cases of mixed total anomalous pulmonary venous connection,which were performed by CT and MRI,all the cases were confirmed by the operative findings.Results A total of 26 patients presenting with mixed total anomalous pulmonary venous connection were identified,all these 26 cases can be classified into 2 groups."3+1" pattern,in which three veins drained at the cardiac level or systemic venous and the other drained to the systemic venous in opposite site,22 cases were in this group,"2+ 2" pattern,in which the veins were from each lung unite and then drained in different sites,2 cases were in this group.The other 2 cases had more than 4 pulmonary veins.Conclusion Mixed total anomalous pulmonary venous connection could be diagnosed accurately by CT and MRI.%目的 探讨CT及MRI对混合型完全性肺静脉异位引流的诊断价值.方法 以手术证实为混合型完全性肺静脉异位引流的26例患儿为研究对象,回顾性分析其CT及MRI影像.结果 26例患儿的CT及MRI影像均清晰显示肺静脉异位引流的途径,诊断的正确率为100％.26例混合型完全性肺静脉异位引流可分为两类,①“3+1”型:3支肺静脉回流人右心房或冠状静脉窦或体循环静脉,而另1支肺静脉则回流入另一侧的体循环静脉,此类共22例；②“2+2”型:指两侧的肺静脉分别回流入不同的位置,此类共2例.另有2例异位引流的肺静脉超过4支.结论 CT及MRI能够准确地诊断混合型完全性肺静脉异位引流.
