OBJECTIVE: To investigate the feasibility of trachea defect repair with "C" shape shape-memory titanium-nickel alloy net (CSSMAN).METHOD: The CSSMAN substitute for the tracheal cartilage and the skin tube for the tracheal mucosa in order to form a new "trachea" shape structure to repair the mongrel dogs trachea defect.RESULT: Four dogs were successfully decannulate, computerized tomography (CT) examination and fibrotracheoscopy examination showed the CSSMAN located perfectly and the airway is wide enough for breath. One dog failed to decannulate due to the infection.CONCLUSION: It is a promising choice to repair the trachea defect with CSSMAN by two-stage procedure.
