title: [Replacement of artificial tracheal prosthesis by two-stage procedure with memory-alloy mesh].
abstract: OBJECTIVE
  To design an artificial trachea which can totally heal with the native trachea.
  
  
  METHODS
  Using memory-alloy mesh as the skeleton to construct an artificial trachea by two-stage operation. After 2-year animal experiment we successfully performed the operation in a patient with recurrent carcinoid of the trachea, radically resected the tumor and primarily reconstructed the trachea.
  
  
  RESULTS
  The inner side of this "sandwich" artificial tracheal prosthesis was coated with skin and outside the memory-alloy mesh was muscle and vessel pedicle with good blood supply. The upper and lower anastomosis completely healed with recipient's trachea with a full recovery of trachea. Six-month follow-up showed that the patients resumed their normal life.
  
  
  CONCLUSIONS
  The artificial trachea completely healed with the native trachea and became a part of the human trachea. The inner side of artificial trachea is coated with intact native skin tissue with ample blood supply, totally alive without rejection. Therefore, the pedicled artificial tracheal prosthesis is an real artificial trachea.
