The use of a single CT scan to evaluate the severity of pectus excavatum has been popular since its inception. However, there is no objective data to address the evolution of the deformity. Using repeated CT scans taken an average of 1 year and 3 months apart, eight children with pectus excavatum were prospectively followed. The initial pectus indices ranged from 3.6 to 6.8 (mean 5.4 +/- 1.3) and the follow-up indices, from 3.5 to 6.7 (mean 5.3 +/- 1.0). No progress of pectus excavatum was found during the study period. Our routine five axial chest CT sections also helped to specify a pectus index based on the central section taken through the deepest part of the deformity, and provided useful information for further conservative or surgical management.
自问世以来，使用单次CT扫描评估漏斗胸严重程度的方法一直很流行。然而，目前尚无客观数据来阐述该畸形的演变情况。我们对8名漏斗胸患儿进行了前瞻性随访，平均每隔1年零3个月进行一次重复CT扫描。初始漏斗胸指数范围为3.6至6.8（平均5.4±1.3），随访指数范围为3.5至6.7（平均5.3±1.0）。在研究期间未发现漏斗胸进展情况。我们常规的五幅胸部轴向CT图像还有助于根据通过畸形最深部位的中央截面确定漏斗胸指数，并为进一步的保守或手术治疗提供有用信息。
