Abstract

Objective To evaluate the impact of Nuss procedure by comparing the dimensional changes of thoracic cavity of pectus excavatum (PE) patients on computed tomography (CT) images. Methods A total of 50 PE cases undergoing Nuss procedure from January 2014 to December 2018 were selected. Retrospective reviews were performed for clinical data and CT examinations of chest. The anteroposterior and transverse diameters were measured at multiple thoracic vertebral levels. Paired-sample t-test was employed for comparing the differences between preoperative and postoperative parameters. And independent sample t-test was performed for comparing the inter-group differences in patient age, gender, insertion time of bar and type of PE. Results The postoperative anteroposterior diameters from T8 to T12 were significantly higher than their preoperative values while T3 to T5 anteroposterior diameters and T8 to T10 transverse diameters were lower than their preoperative values. In children aged under 10 years, the duration of bar placement time ≥2 years and girl gender, the anteroposterior diameter changes were larger than the other groups at multiple vertebral levels (P<0.05) and the differences were statistically significant. Conclusions Anterior chest wall depression significantly improves after Nuss procedure. Early correction and longer correction time offer better corrective outcomes. The transverse diameter of thoracic cavity is somewhat limited in growth. Key words: Thoracic vertebrae; Nuss procedure; Thoracic change; CT measurement; Pectus excavatum

Nuss手术对胸腔的影响及相关因素分析

目的探讨Nuss手术对漏斗胸(PE)患者胸廓尺寸变化的影响。方法选取2014年1月至2018年12月行Nuss手术的PE患者50例。回顾性分析临床资料及胸部CT检查。在多个胸椎水平测量前后径和横径。采用配对样本t检验比较术前、术后参数的差异。采用独立样本t检验比较患者年龄、性别、棒插入时间、PE类型的组间差异。结果术后T8 ~ T12正位径明显高于术前，T3 ~ T5正位径和T8 ~ T10横位径明显低于术前。在10岁以下儿童、棒放置时间≥2年及女生中，多个椎体水平前后径变化均大于其他组(P<0.05)，差异有统计学意义。结论Nuss手术后胸壁前压明显改善。早期矫正和较长的矫正时间可以提供较好的矫正效果。胸腔的横向直径在一定程度上限制了生长。关键词:胸椎;主犯过程;胸变化;CT测量;胸的举
