title: [Diagnosis and treatment of pulmonary sequestration].
abstract: OBJECTIVE
  To explore the cause, classification, incidence, diagnosis and treatment of pulmonary sequestration.
  
  
  METHODS
  42 cases analysed and literatures reviewed.
  
  
  RESULTS
  42 cases of sequestration were presents which were resected and confirmed by pathology in our department from 1964 to 1997. 29 cases (69%) were confirmed before 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. 22 cases accompanied with infection, 9 cases with hemoptysis in intralobar type. 1 case with infection and 1 case with hemoptysis in extralobar type, in the latter case, there was a fistula between the affected lung and the esophagus.
  
  
  CONCLUSIONS
  Pulmonary sequestration is not a rare illness. The diagnosis mainly depends on X-ray. Sometimes, bronchography, retrograde arteriography or CT can also make the diagnosis correctly. Special attention should be paid to avoiding injure to the vessels which supply the isolated lung during operation.
