title: Aortopulmonary fistula.
abstract: BACKGROUND
  Aortopulmonary fistula is an uncommon but usually fatal condition if not treated surgically. The most frequent cause is erosion of a false aneurysm of the descending thoracic aorta into the left lung.
  
  
  METHODS
  Review of charts of all patients who had had resection of a thoracic aortic aneurysm at the MidAmerica Heart Institute (1971 to 1997) revealed three cases in which the presentation was hemoptysis resulting from an aortopulmonary fistula. The clinical features and course of each patient are summarized in this report.
  
  
  RESULTS
  The three patients with hemoptysis due to an aortopulmonary fistula had emergency surgical intervention with no major complication.
  
  
  CONCLUSIONS
  Any patient who has an otherwise unexplained hemoptysis and a history of a previous thoracic aortic surgical procedure or is known to have a thoracic aortic aneurysm should have appropriate clinical evaluation to exclude the presence of an aortopulmonary fistula. If an aortopulmonary fistula cannot be excluded, emergency operation should be done.
