Background/Purpose: Since 1996 a new procedure - the free tracheal autograft - has been used to repair long segment congenital tracheal stenosis (LSCTS). The purpose of this report is to examine the intermediate-term results of that technique. Methods: Between January 1996 and July 1999, 10 infants underwent repair of LSCTS using a free tracheal autograft. Age ranged from 10 days to 23 months (mean age, 6.6 months). Six infants had a pulmonary artery (PA) sling; 5 had intracardiac anomalies. On cardiopulmonary bypass (CPB) the trachea was incised anteriorly through the area of stenosis. The midportion of the stenotic trachea was excised, and an end-to-end anastomosis was made posteriorly. The excised tracheal segment was trimmed and sutured in place anteriorly as a free autograft. In 5 patients the autograft was not long enough, and the upper portion of the tracheal opening was patched with pericardium. Results: There was 1 death 26 days postoperatively in a child that had simultaneous repair of tetralogy of Fallot and required extracorporeal membrane oxygenation postoperatively for cardiac failure. The other 9 children are alive and well at 2 to 44 months postoperatively (mean follow-up, 24 months). One child had autograft dehiscence and required replacement of the autograft with an aortic homograft. Two children have tracheostomies at 6 and 36 months postoperatively. All children have had serial postoperative bronchoscopic examinations. Most recent bronchoscopies have shown widely patent tracheal lumina in all survivors. Conclusion: Intermediate-term follow-up of children with a free tracheal autograft continues to support our use of this technique as our procedure of choice for infants with LSCTS.
