[Experimental replacement of the trachea by dacron-silicone rubber prosthesis]

Experimental results of trachea replacement by dacron-silicone rubber tube in rabbits and dogs were presented. The techniques for anastomosis of the prosthesis to the host trachea, prevention of obstruction by granulation and the dynamic effects of air current during cough reflex caused by the artificial trachea were also investigated. Experiments showed that the use of artificial trachea with right size (inner diameter) was the key to maintain expectoration mechanism. When the artificial trachea was constructed on proper selected cases, complications resulting from use of Nevilles are preventable.
