多层螺旋CT在儿童完全性肺静脉异位引流诊断中的研究

目的:探讨多层螺旋CT在完全性肺静脉异位引流中的诊断价值。方法:回顾性分析2005年5月～2010年4月经心脏外科手术证实的30例完全性肺静脉异位引流患儿的MSCT图像特点,探讨MSCT在完全性肺静脉异位引流及并发畸形诊断中的价值,为术前诊断、手术方式选择及术后随访提供信息。结果:30例中心上型15例,心内型12例,心下型2例,混合型1例;术前经MSCT诊断为完全型28例(心上型15例,心内型10例,心下型2例,混合型1例),漏诊2例,诊断符合率为93.3%;TTE诊断心上型11例,心内型9例,心下型1例,漏诊9例,诊断符合率为70.0%。结论:多层螺旋CT是完全性肺静脉异位引流准确、重要的检查方法。

Application of multi-slice spiral CT in diagnosis of total anomalous pulmonary venous drainage in children

Objective:To explore the value of multi-slice spiral CT(MSCT) in diagnosis of total anomalous pulmonary venous drainage(TAPVD) in children.Methods:The imaging characteristics of MSCT among 30 children with TAPVD who were diagnosed definitely by department of cardiac surgery in the hospital from May 2005 to April 2010 were analyzed retrospectively,the value of MSCT in diagnosis of TAPVD combined with abnormality was explored,then the information was provided for preoperative diagnosis,choice of operative modes and postoperative follow-up.Results:The types of TAPVD among 30 children:15 children with supra-cardiac type,12 children with intra-cardiac type,2 children with infra-cardiac type and 1 child with mixed type;28 children were diagnosed as complete type by MSCT before surgery(15 children with supra-cardiac type,10 children with intra-cardiac type,2 children with infra-cardiac type and 1 child with mixed type),2 children were missed,the diagnostic accordance rate was 93.3%.The results of TTE:11 children with supra-cardiac type,9 children with intra-cardiac type,1 child with infra-cardiac type,9 children were missed,the diagnostic accordance rate was 70.0%.Conclusion:MSCT is a accurate and important diagnostic method in children with TAPVD.
