MSCTA对肺静脉异位引流的诊断价值

目的：比较多层螺旋CT血管成像（MSCTA）和经胸超声心动图（TTE）对肺静脉异位引流的诊断价值。方法：对2007年9月～2009年5月22例临床怀疑先天性肺静脉异位引流的患儿行MSCTA检查及TTE检查,并与手术结果相对照。结果：经手术证实22例病例中,完全性肺静脉异位引流13例,其中心上型6例,心内型5例,心下型2例;部分肺静脉异位引流9例,其中心上型8例,心内型1例。MSCTA和TTE的诊断符合率分别为96%和73%。结论：MSCTA是诊断先天性肺静脉异位引流的重要手段。

Value of the multi-slice spiral CT angiography in the diagnosis of anomalous pulmonary venous connection

Objective：To compare the value of the multi-slice spiral CT angiography （MSCTA） with that of transthoracic echocardiography （TTE） in the diagnosis of anomalous pulmonary venous connection.Methods：From September 2007 to May 2009,22 cases of suspected congenital anomalous pulmonary venous connection of children underwent MSCTA and TTE examination in comparison with surgical results.Results：The surgically confirmed 22 cases included total anomalous pulmonary venous connection in 13 cases：supra-cardiac （6 cases）,intra-cardiac （5 cases） and infra-cardiac （2 cases）.There was partial anomalous pulmonary venous connection in 9 cases,included supra-cardiac （8 cases） and intra-cardiac （1 case）.The diagnostic accuracy of MSCTA and TTE was 96% and 73%.Conclusion：Multi-slice spiral CT angiography is an important means in the diagnosis of congenital anomalous pulmonary venous connection.
