[Results of tracheal reconstructive surgery using homografts preserved in formaldehyde].

The present study was designed to investigate the results of homograft of cervical trachea preserved in formaldehyde. Surgical approach consists in end-to-end anastomosis. In all our cases the graft was rejected, and the animals could only live 13 days as a maximum. We find tracheal mucosa is responsible for graft antigens. The results both clinical and histopathological are compared with a control group and with those obtained by other authors using different conservation methods.
