A technic of tracheal, carinal or bronchial transplantation using a stented cryopreserved aortic has been implemented by Pr E. Martinod in his thoracic surgery dept. The purpose of this study is to analyze the records of all the patients who have benefited from this treatment.
In the context of end-stage tracheobronchial disease (in particular tracheal or carinal indication) this technic propose a therapeutic alternative, in the context of bronchial replacement it allows to avoid pneumonectomy.
The advantages are to reduce mortality at 90 days, functional consequences and long-term complications.
In this observationnel study, data were collected prospectively in the medical records of all patients who have undergone a trachea or artificial bronchus transplant.

| Tracheal, carinal or bronchial transplantation using a stented cryopreserved aortic | Procedure | Radical resection of the lesions was performed using standard surgical techniques. After resection, airway reconstruction was performed using a human cryopreserved (-80°C) aortic allograft, which was not matched by the ABO and leukocyte antigen systems. To prevent airway collapse, a custom-made stent was inserted into the allograft. In patients with proximal lung tumors, the lung-sparing intervention of bronchial transplantation was used. |

Inclusion Criteria:Eligible patients were treated by human cryopreserved (-80°C) aortic allograft after undergoing a standard preoperative evaluation and cardiopulmonary tests. A multidisciplinary team approve d the treatment based on the following criteria: Patients (1) had proximal lung tumors requiring a surgical resection (pneumonectomy, carinal resection, or sleeve lobectomy) that may or may not have been treated with neoadjuvant chemotherapy and had adequate or compromised preoperative lung function tests; or (2) had significant major malignant or benign lesions of the trachea and bronchi untreated with conventional therapeutic approaches, and (3) have signed an informed consent form for this specific surgical intervention.
Exclusion Criteria:Patients were not treated by human cryopreserved (-80°C) aortic allograft if they :
(1) had a lung tumor requiring a standard lobectomy; (2) had nonresectable major locally invasive tumors; (3) had contralateral lymph node invasion; (4) had metastatic disease with the exception of a unique resectable brain metastasis; (5) had tracheal lesions requiring standard resection with direct anastomosis; (6) had an iodine allergy; or (7) received a preoperative evaluation indicating an inability to undergo a standard lobectomy.
