简介：各种尺度和测量方法，包括X线和计算机断层扫描（CT）已被用来量化漏斗胸畸形的程度。本研究描述了一种非侵入性的方法来记录漏斗胸（PE）患者的前胸壁（ACW）的偏差。使用这种非侵入性的方法获得的数据进行了比较与CT data.Materials和方法：21例患者在我们的机构治疗2008年6月至2009年2月参加了这项研究。所有患者均行CT及热塑条测量。在仰卧位患者的ACW上，从腋后线开始，在胸骨凹陷处，到对侧腋后线的皮肤水平处，定位并贴上热塑料条，并用于创建ACW的模型。漏斗胸凹陷指数（CI）定义为漏斗胸凹陷区的宽度除以其深度。Pearson相关系数用于比较热塑条法和CT法获得的FI和CI;发现两种方法获得的测量值具有良好的相关性（FI：r（2）= 0.965; CI：r（2）= 0.947）。结论：热塑条测量法提供了前胸壁形状的二维记录。该测量可以重复，不涉及患者暴露于辐射，并提供了一个很好的纵向评估PE患者的胸壁生长。
Introduction: Various scales and measurement methods including X-rays and computed tomography (CT) have been used to quantify the degree of deformity in pectus excavatum. This study describes a non-invasive method for recording the deviation of the anterior chest wall (ACW) in pectus excavatum (PE) patients. Data obtained using this non-invasive method were compared with CT data.Materials and Methods: Twenty-one patients treated at our institutions between June 2008 and February 2009 were enrolled in this study. All patients underwent CT and thermal plastic strip measurement. A thermal plastic strip was positioned and taped to the supine patient's ACW at the skin level from the posterior axillary line, over the depressed sternum, to the contralateral posterior axillary line and used to create a casting of the ACW.Results: The funnel index (FI) was defined as the width of the ACW divided by its height; the concave index (CI) was defined as the breadth of the depressed area of the funnel chest divided by its depth. Pearson's correlation coefficient was used to compare the FI and CI obtained with the thermal plastic strip method and with CT; measurements obtained with both methods were found to correlate well (FI: r(2) = 0.965; CI: r(2) = 0.947).Conclusions: The thermal plastic strip measurement method provides a two-dimensional record of the shape of the anterior chest wall. The measurement can be repeated, does not involve the patient being exposed to radiation, and offers a good longitudinal assessment of chest wall growth in PE patients.
