[Tracheobronchial healing in lung or heart-lung transplantation. An anatomical study of forty anastomoses in men].
The post operative evaluation and endoscopic follow-up of 34 tracheal or bronchial anastomoses after lung or heart-lung transplantation show some aspects of the tracheobronchial healing and difficulties in the healing process: primary type I mucomucosal healing in only 6 cases, secondary type II mucosal healing in 15, delayed type III healing after mucosal or deep parietal necrosis in 13, type IV distant ulcerations of mucosa and spur lesions in 12. Type III difficulties of healing mainly occur after double-lung transplantations which always suffer from ischemia. Autologous tracheal or bronchial sutures in 3 transplanted patients submitted to standard immunosuppressive therapy including corticosteroids were uneventful and type I. This experience suggests that among all factors having an influence on bronchial healing, ischemia of the donor tracheobronchial tree is predominant, justifying all attempts of bronchial revascularization after double-lung transplantation. The efficacy of the arterial revascularization is verified in 3 cases of tracheal anastomosis after double-lung transplantation with type I or II tracheal healing.
