post-obstructive process？

Chest radiographs are often performed due to convenience, efficiency, portability, and cost-effectiveness. Chest radiographs should be considered in all patients with suspected tracheal stenosis as they may reveal pathology of the airways and the lung parenchyma [18]. The radiographs may show tracheal deviation or mediastinal shift due to mass effect, lung parenchymal consolidation due to complete obstruction of airway or post-obstructive process, or signs of underlying lung disease associated with tracheal stenosis. However, they are rarely diagnostic due to the inherent nature of the study, which does not allow for a full three-dimensional visualization of the tracheal lumen and its nearby structures. In clinical practice, chest radiographs are more readily utilized in assessing complications of airway procedures such as pneumothorax, pneumomediastinum, and atelectasis. They also allow for a quick assessment of metallic stent positioning, change in lung aeration, and as a reference for future assessments.

由于方便、高效、便携和低费用，常行胸片检查。因为可能显示气道和肺实质的病变，所有疑似气管狭窄的患者均应考虑胸片检查[18]。胸片可显示占位效应引起的气管偏移或纵隔移位、因气道完全阻塞或阻塞后过程引起的肺实质实变，或与气管狭窄相关的潜在肺病征像。但是，由于胸片的固有性质——无法实现气管腔及其附近结构的完整三维可视化，很少具有诊断价值。在临床实践中，胸片更容易用于评估气道手术的并发症，如气胸、纵隔气肿和肺不张。它们还能快速定位金属支架、评估肺通气变化，并作为未来评估的参考。
