title: [Bronchopulmonary sequestration: review of 27 cases].
abstract: OBJECTIVE
  To explore the clinical manifestations, the diagnosis and the treatment of bronchopulmonary sequestration.
  
  
  METHODS
  Twenty-seven cases of bronchopulmonary sequestration confirmed by histopathological studies were analyzed and related literatures were reviewed.
  
  
  RESULTS
  Among the 27 cases of bronchopulmonary sequestration, 22 were intralobar type, and 5 were extralobar type. All the patients with intralobar type had symptoms including cough, expectoration, fever, hemoptysis, but the 5 cases of extralobar type had no symptoms. Twenty cases were confirmed before operation by chest radiography, plain CT scan, enhanced CT scan, CT angiography, MR angiography, or selective arteriography. Chest operation was performed in all the cases, with successfully recovery after the operation, and no relapse was found.
  
  
  CONCLUSIONS
  The clinical manifestations of bronchopulmonary sequestration are nonspecific. Selective arteriography, although invasive, plays a pivotal role in the diagnosis. Non-invasive angiography including enhanced CT scan, CT angiography, and MR angiography have become important supplements to selective arteriography. Surgery is the optimal treatment, while the effect of interventional therapy needs further study.
