ABSTRACT
Objective: To make an artificial trachea, which can really healed with native trachea. Methods: 20 dogs are randomized into a pedicle group and a nonpedicle group. 6 cm cervical trachea was resected and replaced with "sandwich" artificial trachea made from memory alloy meshes by two-stage operative procedure. Survival period and stenosis of anastomosis were recorded. Results: Seven dogs in pedicle group survived well and another three were dead. The cause of death was anastomosis stricture in 1 and infection in 2. All dogs in nonpedicle group were dead within four weeks because of stenosis or infection. Conclusion: Two-stage operative pedicle "sandwich" artificial trachea made from memory alloy mesh is up to now the closest artificial trachea to human native trachea. It could be applied clinically.
