Objective To summarize the clinical manifestations, diagnosis and treatment of pulmonary sequestration. Methods The clinical data of 22 cases with pulmonary sequestration were reviewed retrospectively. Results Twenty-two cases(9 males and 13 females) with pulmonary sequestration were operated and the diagnosis was confirmed by pathology. Twenty cases had the symptoms of cough,expectoration, fever, hemoptysis, chest pain and oppression in chest, and 2 cases were asymptomatic. Four cases got confirmed diagnosis before operation and 18 eases were misdiagnosed as tumor,cyst,bronchiectasis,abscess or pneumonia. Chest X-ray immages showed the left lower lobe lesions in 15 cases,the right lower lobe lesions in 5 cases. The pulmonary sequestration was intralobar type in 19 cases and extralobar type in 3 cases. No late complications occurred.Conclusion The clinical manifestations of pulmonary sequestration are non-specific. Contrast enhanced CT, CT angiography and selective arteriography are the major diagnostic methods. Surgery is the major treatment for pulmonary sequestration.%目的 总结肺隔离症的临床表现、诊断和治疗.方法 回顾性分析22例肺隔离症患者临床资料.结果 22例肺隔离症均手术切除并经病理证实.2例患者无症状;其余患者临床表现为咳嗽、咳痰、发热、咯血、胸痛和胸闷.4例术前诊断;其余18例术前误诊为肿瘤、囊肿、支管扩张或脓肿或肺炎.影像检查显示左下叶病变15例,右下叶病变5例.叶内型19例,叶外型3例.术后无并发症.结论 肺隔离症临床表现无特异性,CT增强、CT血管造影、选择性动脉造影对显示异常动脉有重要价值.手术切除是肺隔离症的主要治疗方法.
