Tracheal diverticulum (DV) is an incidental finding in thoracic computed tomography examinations. Tracheal DV may be associated with chronic cough and chronic obstructive pulmonary disease (COPD). A few studies have investigated the relationship between tracheal DV and COPD. There is still no consensus on the relationship. The purpose of this study was to determine the incidence of tracheal DV and its coexistence with bronchial DV and hyperaeration.
For the study, 299 patients from a total number of 12 800 patients who underwent a thoracic computed tomography examination were included. Tracheal diverticula were evaluated for localization, size, contour, wall thickness and communication with the tracheal lumen. The association of tracheal DV with bronchial DV and hyperaeration was also noted. The relationship between tracheal DV and hyperaeration was analyzed.
Of the 299 patients, a total of 412 tracheal diverticula were observed. Out of these, 148 of the tracheal diverticula were in females, and 264 of the tracheal diverticula were in male patients. The incidence of tracheal DV was determined to be 2.38% in this study. In total, 400 of the tracheal diverticula (97.1%) were located at the right posterolateral aspect of the trachea, and 320 of the tracheal diverticula were associated with hyperaeration. There was no significant relation between the tracheal DV and hyperaeration. However, 84 of 412 tracheal diverticula had a bronchial DV, and 72 of 84 of these bronchial DV were associated with COPD. Statistical analysis indicated a significant correlation with COPD and bronchial DV (p<0.05).
Tracheal DV is often asymptomatic and mostly located in the right posterolateral aspect of the trachea. Tracheal DV is more common in men than in women. The incidence of tracheal DV was 2.38% in this study. Our data demonstrate that there was no significant association between tracheal DV and COPD. However, there was a significant association between subcarinal bronchial DV and COPD.
气管憩室（DV）是胸部计算机断层扫描检查中的偶然发现。气管DV可能与慢性咳嗽和慢性阻塞性肺疾病（COPD）相关。少数研究调查了气管DV与COPD之间的关系。关于这种关系仍未达成共识。本研究的目的是确定气管DV的发生率及其与支气管DV和肺过度充气的共存情况。
本研究纳入了12800例接受胸部计算机断层扫描检查的患者中的299例。对气管憩室进行定位、大小、轮廓、壁厚度以及与气管腔连通情况的评估。还记录了气管DV与支气管DV和肺过度充气的关联。分析了气管DV与肺过度充气之间的关系。
在299例患者中，共观察到412个气管憩室。其中，148个气管憩室见于女性患者，264个气管憩室见于男性患者。本研究中气管DV的发生率确定为2.38%。总体而言，400个气管憩室（97.1%）位于气管右后外侧，320个气管憩室与肺过度充气相关。气管DV与肺过度充气之间无显著关系。然而，412个气管憩室中有84个伴有支气管DV，其中84个支气管DV中的72个与COPD相关。统计分析表明COPD与支气管DV之间存在显著相关性（p<0.05）。
气管DV通常无症状，大多位于气管右后外侧。气管DV在男性中比在女性中更常见。本研究中气管DV的发生率为2.38%。我们的数据表明气管DV与COPD之间无显著关联。然而，隆突下支气管DV与COPD之间存在显著关联。
