[Experimental study progress of tracheal allografts undergoing revascularization and reepithelialization].

OBJECTIVE

To study the research advance in tracheal allografts undergoing revascularization and reepithelialization.

METHODS

The recent literature concerned was reviewed. The tracheal allografts are embedded in the omentum, which they were revascularized and reepithelialized by planting in self-epithelia, then the allografts with their omental pedicles were transplanted orthotopically to the cervical or the thoracic portion of the trachea.

RESULTS

Compared with the one-stage tracheal allograft approach using the greater omentum, the two-stage approach could increase the successful rate of revascularization and reepithelialization, and made the allografts accord with their physiology.

CONCLUSION

If the approach is successful, it can reduce graft-rejection, prevent graft-collapse and increase graft-viability after tracheal allograft.
