title: Mediastinal bronchial artery aneurysm treated with a stent-graft.
abstract: OBJECTIVE
  To report a rare case of mediastinal bronchial artery aneurysm successfully treated with an endovascular stent-graft.
  
  
  METHODS
  A 79-year-old man with a history of tuberculosis was admitted to our hospital complaining of worsening hoarseness. Examination revealed a large mediastinal bronchial artery aneurysm located near the origin of the artery. Since neither surgical intervention nor transcatheter embolization was feasible, an endovascular stent-graft repair was performed using a newly developed stent-graft constructed from a nitinol stent and a thin membrane of polyester. Postprocedural angiography showed satisfactory exclusion of the aneurysm. The patient made an uneventful recovery. The 18-month computed tomographic scan documented continued exclusion of the aneurysm, with no evidence of endoleak, graft thrombosis, or migration.
  
  
  CONCLUSIONS
  When conventional procedures are too complicated for bronchial artery aneurysms, endovascular stent-graft repair can be a useful approach.
