Tracheobronchial Bioengineering Using Aortic Matrices for Airway Reconstruction

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.
