Feasibility of Tracheobronchial Reconstruction Using Allogenic Aortic Patch in Children

Feasibility and safety of repairing tracheal and bronchial defects in infants and children using cryopreserved donor aortic patches.

This trial plans to use cryopreserved donor aortic tissue patches to repair and treat pediatric patients with end-stage, life-threatening or severely disabling tracheal diseases who have not responded to conventional conservative therapies or lack sufficient native tracheal tissue for tracheal defect reconstruction.
