title: Late perforation of a thoracic aortic dacron graft by a metallic stent-graft component.
abstract: OBJECTIVE
  To describe a case involving perforation of a previously placed aortic Dacron graft by the uncovered proximal stent of a thoracic stent-graft.
  
  
  METHODS
  A 76-year-old man with a surgically treated type A dissection presented with residual type B dissection. Thoracic stent-grafting of the entry site was performed successfully. After 2 years, the patient was admitted for evaluation of a non-pulsating parasternal mass. Computed tomography showed a large, hypodense liquid-like mass affecting the mediastinum up to the subcutaneous tissue. A false aneurysm at the proximal end of the stent-graft was observed arising from an aortic perforation by the uncovered stent. One week later, the mass had almost completely resolved, and the patient has been scheduled for close surveillance.
  
  
  CONCLUSIONS
  This case illustrated the importance of thoroughly examining the long-term durability and compatibility of prosthetic materials.
