【摘要 】 目的 对肺隔离症的病因、分类、发病率，诊断及治疗加以探讨。方法 回顾分析42例肺隔离症的临床资料及文献复习。结果 自1964～1997年间通过手术切除并经病理证实的42例肺隔离症。发病率占同期手术的0.32%，其中叶内型37例(88%)，叶外型5例(12%)。叶内型22例合并感染症状，9例合并咯血症状。叶外型1例合并感染症状，1例合并咯血症状，该病例隔离肺与食管相通。术前确诊或拟诊29例(69%)。结论 肺隔离症诊断方法主要为X线检查，支气管碘油造影，选择性动脉造影及CT检查。术中应避免损伤隔离肺的营养血管，对叶外型肺隔离症应注意其它脏器的畸形。

【Abstract 】 Objective Toexplore the cause, classification, incidence, diagnosis and treatment of pulmonarysequestration. Method 42 casesanalysed and literatures reviewed. Result 42 cases of sequestration were presents which were resected andconfirmed by pathology in our department from 1964 to 1997. 29 cases (69%) were confirmedbefore operation. The incidence rate was 0.32% comparing with the sametime operations.There were 37 cases (88%) of intralobar type, and 5 cases (12%) of extralobar type. 22cases accompanied with infection, 9 cases with hemoptysis in intralobar type. 1 case withinfection and 1 case with hemoptysis in extralobar type, in the latter case, there was afistula between the affected lung and the esophagus. Conclusion Pulmonary sequestration is not a rare illness. The diagnosis mainlydepends on X-ray. Sometimes, bronchography, retrograde arteriography or CT can also makethe diagnosis correctly. Special attention should be paid to avoiding injure to thevessels which supply the isolated lung during operation.
