Study of tracheal allograft transplantation in adults dogs

Abstract EN

The present study was done to investigate the ability of tracheal allograft transplantation in adult dogs and evaluate the health condition of the outcome of the allograft transplantation respect of the healing.

Two groups of adult dogs (each group 4 dogs) were used as both donors and recipients.

A rectangle tracheal allograft was transplanted in recipient dog and fixed by suturing, gross evaluation showed that there are no signs of tracheal stenosis or any complication like difficult breathing and blood stained coughing, the animals remained in good health throughout the procedure.

Histopathological examination one month after transplantation revealed prominent cartilage enclosed by fibrosis and absence of any infiltration of inflammatory cells while histopathological finding 2 months after operation showed sub epithelial fibrosis and presence of cartilage.

This will give indication that tracheal allograft can be used as tissue replacement for treatment of tracheal defects.
