Research progress of tracheal replacement / 中国胸心血管外科临床杂志

ABSTRACT

@#Severe tracheal stenosis, which commonly results from tumor of trachea, tracheal trauma, congenital deformity constitutes a threaten for patient life, thus it needs for tracheal resection and reconstruction.For defects less than 5 cm, it can be repaired by direct end-to-end anastomosis. But for large area (more than 6 cm), it needs numerous different types of materials and techniques. These alternatives include allograft transplantation, autologous tissue transplantation, tissue engineering materials, and so on. In recent years, due to the rapid development of surgical techniques, the tracheal surgery has considerable development. In this paper, we will discuss tracheal allograft transplantation and tissue engineering trachea in tracheal replacement research progress.
