Pectus excavatum is the most common congenital chest wall deformity, with a high incidence in live births. This study aimed to evaluate the measured factors on CT images related to the number of pectus bars for surgical correction.
A total of 497 patients who had undergone minimally invasive repair between April 2007 and July 2011 were classified into single-bar (n=358) and double-bar (n=139) insertion groups. We measured eight distinct distances and one angle on CT scans to reflect quantitative assessment. Univariate analysis and multivariate logistic regression analysis were performed to detect statistically significant association between radiologic measurements and the pectus bars required.
After adjusting for age and gender, the transverse distance (T), the transverse distance of the depression area (A), the inclined distance of the depression area (B), the AP distance of the depression area (C), the depression angle (G), and the eccentric distance of deformity (E) were significantly correlated with double-bar insertion. The regression model showed that age (P<0.0001), gender (P<0.0001), depression angle (G) (P<0.0001), direction of the depression (DD) (P<0.0001) and depression depth (D) (P<0.0001) were significantly associated with double-bar insertion.
CT scan provides useful factors which can be of assistance in predicting the number of pectus bars for the surgical correction of pectus excavatum.
漏斗胸是最常见的先天性胸壁畸形，在活产婴儿中发病率较高。本研究旨在评估CT图像上与手术矫正所需漏斗胸钢板数量相关的测量因素。
将2007年4月至2011年7月间接受微创修复的497例患者分为单钢板植入组（n = 358）和双钢板植入组（n = 139）。我们在CT扫描上测量了八个不同的距离和一个角度以进行定量评估。进行单因素分析和多因素逻辑回归分析，以检测放射学测量与所需漏斗胸钢板之间的统计学显著关联。
在调整年龄和性别后，横径（T）、凹陷区域横径（A）、凹陷区域斜径（B）、凹陷区域前后径（C）、凹陷角度（G）和畸形偏心距（E）与双钢板植入显著相关。回归模型显示，年龄（P < 0.0001）、性别（P < 0.0001）、凹陷角度（G）（P < 0.0001）、凹陷方向（DD）（P < 0.0001）和凹陷深度（D）（P < 0.0001）与双钢板植入显著相关。
CT扫描提供了有用的因素，有助于预测漏斗胸手术矫正所需的漏斗胸钢板数量。
