[Replacement of artificial tracheal prosthesis by two-stage procedure with memory-alloy mesh].

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.
