The application of solvent-processed human dura in experimental tracheal reconstruction.

Abstract:

:To evaluate the role of solvent-processed human cadaveric dura in experimental tracheal reconstruction, anesthetized piglets underwent an elliptical excision of a four-ring segment of the trachea. Twelve animals were randomly divided into two equal groups: in group I, the resected trachea was rotated 180 degrees and sutured into position; in group II, the resected trachea was replaced with dura. The animals were extubated after the operation, and endotracheal stents were not used. Tracheal dimensions were recorded, and tissues were evaluated for mechanical compliance (percent elongation/displacement). Histology of the grafts was characterized by fibrosis and granulation tissue, and there were no distinguishing features between groups. The data suggest that solvent-processed human dura has compliance and patency comparable to those of autologous free-grafted trachea and that it may prove useful as an adjunct to reconstructive tracheal surgery in infants.
