The application of CT-based pulmonary volumetric evaluation in the development of thoracic volume of pectus excavatum use of Nuss operation / 中华胸心血管外科杂志

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.
