【摘要】 目的 总结肺气肿合并肺间质纤维化的临床特点并探讨其临床意义。方法 分析5年来我院确诊的11例肺气肿合并肺间质纤维化患者的症状、X线胸片、血气分析、肺功能、CT结果。结果 肺气肿合并肺间质纤维化患者多具有较长的吸烟史，临床表现介于上述两种病变之间，其肺功能测定结果不完全符合阻塞型或限制型通气功能障碍，X线及CT兼具二者的特点。结论 尽管肺气肿和肺间质纤维化是两种不同的疾病，但是确实可以并存，且具有其独特的临床表现，胸部高分辨CT(HRCT)往往能为临床提供重要的诊断依据。

【Abstract】 Objective Emphysema andinterstitial pulmonary fibrosis are two different diseases in clinical manifestation andpathology, but it was noticed that there were cases diagnosed as pulmonary emphysema andpulmonary fibrosis. It is necessary to study the relationship between the clinical aspectsof these cases. Methods 11 patients with emphysema and pulmonaryfibrosis were found in the past five years. Clinical symptoms, radiographic features,arterial blood-gas, lung funtion testing and computed tomography of the chest wereanalyzed. Results These patients had a long history ofcigarette-smoking , Their clinical features are those of both emphysema and pulmonaryfibrosis. Conclusions Although emphysema and interstitial pulmonaryfibrosis are two different diseases, they could coexist in some patients. Theirclinical features do not like either of the two diseases. HRCT is an important method fordiscovering the coexistance of pulmonary emphysema and interstitial fibrosis.
