[Experimental study of tracheal defect repair with shape-memory titanium-nickel alloy net].
OBJECTIVE
To investigate the feasibility of trachea defect repair with "C" shape shape-memory titanium-nickel alloy net (CSSMAN).


METHODS
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.


RESULTS
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.


CONCLUSIONS
It is a promising choice to repair the trachea defect with CSSMAN by two-stage procedure.
