title: Fabricated bronchial artery embolization for hemoptysis using a coil.
abstract: BACKGROUND
  Bronchial artery embolization is considered a conservative form of therapy for hemoptysis. This study aimed to examine the short- and long-term effects of bronchial artery embolization, as well as the performance of the coils used in our hospital.
  
  
  METHODS
  We reviewed the background, symptoms, findings, and prognosis of 27 cases of bronchial artery embolization for hemoptysis between April 2003 and October 2011. For embolization materials, short coils combined with a long interlocking detachable coil were mainly used from March 2008.
  
  
  RESULTS
  Aspergillosis and chronic empyema comprised the majority of cases. In terms of short-term results, there were 25 successful cases of bronchial artery embolization and 2 unsuccessful cases. Regarding the long-term outcome of the successful cases, during an average observation period of 17 months, one patient required repeat bronchial artery embolization, and one was admitted to another hospital with recurrent hemoptysis.
  
  
  CONCLUSIONS
  Bronchial artery embolization for hemoptysis was preformed in a safe and minimally invasive manner with positive results over both the short- and long-term, thus underscoring its utility as a form of treatment. Furthermore, by combining the use of long and short coils, we were able to reduce the number of coils necessary for the procedure, and thus reduce the time and cost involved.
