title: Use of Suture-Mediated Closure Device in Percutaneous Direct Carotid Puncture During Chimney-Thoracic Endovascular Aortic Repair.
abstract: BACKGROUND
  Insertion of a carotid chimney graft during thoracic endovascular aortic repair (Ch-TEVAR) is a recognized technique to extend the proximal landing zone into the aortic arch in the treatment of thoracic aortic disease. Conventional technique requires surgical exposure of the carotid artery for insertion of the carotid chimney graft.
  
  
  METHODS
  We describe our experience in the use of a suture-mediated closure device in percutaneous Ch-TEVAR in four patients.
  
  
  RESULTS
  Successful hemostasis was achieved in all four patients. No complications related to the carotid puncture were recorded.
  
  
  CONCLUSIONS
  We conclude that using suture-mediated closure device for carotid closure appears feasible and deserves further studies as a potential alternative to conventional surgical approach.
