Abstract
We have performed tracheal transplantation, resection of a tumor, and pulmonary resection in 4 cases of tumors of the trachea (2 cases of tracheal cancer and each one of amyloidosis and leiomyoma). Their postoperative courses were satisfactory except one case undergoing tracheal transplantation. Tumors of the trachea are not very rare and it is none too difficult to remove a tumor surgically if it is benign. On the contrary malignant tumors require tracheal resection and transplantation using artificial graft. We report our results of animal experiments through which we have had a clew for tracheal transplantation using natural rubber.
