[Diagnosis and treatment of pulmonary sequestration]
1Thoracic Surgery Department of Shanghai, First Pulmonology Hospital, Shanghai 200433.
Objective:
To explore the cause, classification, incidence, diagnosis and treatment of pulmonary sequestration.
Method:
42 cases analysed and literatures reviewed.
Result:
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.
Conclusion:
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.
