Abstract
Historically, the healing of tracheal or bronchial anastomoses has been the Achilles heel in pulmonary transplantation. In the past, steps taken to enhance healing of these structures and have allowed single-lung, double-lung, and heart-lung transplantation to be accomplished safely. This report presents a simplified technique for protection of the tracheal anastomosis in heart-lung and double-lung transplantation. This technique, wherein the pericardial fat pad from the right side is utilized to wrap the tracheal anastomosis, not only allows for excellent healing of the anastomosis but separates the aorta from the trachea. In 19 patients having heart-lung (N = 13) or double-lung (N = 6) transplantation there were no tracheal healing problems, dehiscence or stenosis found.
