目的通过CT容积重建对比评估Nuss手术对漏斗胸患儿胸廓发育的保护作用.方法选取北京儿童医院胸外科行Nuss手术治疗漏斗胸患儿98例,术前、术后分别行胸部CT检查,应用域值限定及容积再现三维肺模型建模后处理技术计算患儿肺容积,查询在儿童CT肺容积发育量表中的发育程度.定量对比术前、术后发育程度的变化,评估Nuss手术对漏斗胸患儿胸廓发育的影响.结果术后肺容积较术前提高约28.3％.与发育量表对比,胸廓发育较前可以与术前保持一致,70％的患儿胸廓容积发育水平维持了术前的发育水平,15％的患儿发育较前有提高.结论基于CT的肺容量测算法测量的胸廓容积发育结果显示,Nuss手术可以有效阻止漏斗胸患儿胸廓容积的进一步减少.

Objective To access the development of thoracic volume of pectus excavatum use of Nuss operation used CT-basedpulmonary volumetric evaluation.Methods 98 patients with pectus excavatum in Beijing Children's Hospital under Nuss operation were documented.All patients had CT scan pre-and postopration.The CT-scan's data were calculated as lung's volume by handdraw-layers summation method.The lung's volume result was compared,and enquiry the position in CT lung volume developmental scale.Results The lung's volume was elevated 28.3％ after operation.The development of thoracic volume was keep with age,70％ was maintained and 15％ was elevated.Conclusion Nuss operation can prevent the decrease of thoracic volume in pectus excavatum.
