Tracheal Transplantation.

Airway stenosis and malignant tumors are the 2 main reasons to perform a surgical resection of part of the trachea. Tracheal lesions with a length shorter than 5 cm can be resected and primary reconstruction can be safely effected. Excessive anastomotic tension should be avoided because it may lead to restenosis or dehiscence at the anastomosis. Reconstruction of a longer defect may be attempted with a tracheal allotransplant or with autologous tissue.
