摘　　要：目的了解纵隔气肿的解剖基础,探讨纵隔气肿的形成机制及潜在通道,提高纵隔气肿的诊断水平。方法回顾性分析33例纵隔气肿的X线及CT表现。结果本组33例纵隔气肿的原因多种多样,如颈胸部的外伤、气管插管、咽部及气管异物、胸部手术后、肺部炎症、慢支肺气肿,间质性肺气肿等。结论颈部、纵隔、腹腔、肺间质之间存在潜在的间隙,进入任何间隙内的积气可沿着结缔组织的分布于各间隙间蔓延分布。Objective To understand the anatomical basis of pneumomediastinum, explore the formation mechanism of pneumomediastinum and potential channels, so as to improve the level of diagnosis. Methods A retrospective analysis was conducted concerning X-ray and CT manifestations of 33 cases with mediastinal emphysema. Results All the 33 cases with mediastinal emphysema resulted from various causes, such as neck-chest trauma, endotracheal intubation, foreign body in phar- ynx and trachea, post-operation of chest,lung inflammation, chronic bronchitis, and interstitial emphysema. Conclusion There exists a potential gap between the neck, mediastinum, abdominal cavity, and interstitial tissue of lung. The gas, once entering any gap, can spread among all the gaps along the connective tissues.
