目的探讨阻塞性肺不张的病因。方法回顾性分析120例阻塞性肺不张患者的影像学、纤维支气管镜及病理学检查资料。结果肺段叶不张是阻塞性肺不张的主要类型,中央性肺癌为阻塞性肺不张的主要原因,鳞癌为肺癌的主要病理类型。结论肺癌是中老年阻塞性肺不张的主要原因,纤维支气管镜检查在明确阻塞性肺不张的原因中具有非常重要的价值。
Objective To investigate the etiology of obstructive atelectasis. Methods A retrospective analysis of 120 cases of obstructive atelectasis in patients with imaging, bronchoscopy and pathological examination data. Results Pulmonary atelectasis was the main type of obstructive pulmonary atelectasis. Central lung cancer was the main cause of obstructive pulmonary atelectasis. Squamous carcinoma was the main pathological type of lung cancer. Conclusion Lung cancer is the main cause of obstructive atelectasis in middle-aged and elderly patients. Fiberoptic bronchoscopy has a very important value in clarifying the causes of obstructive pulmonary atelectasis.
