Slide tracheoplasty for congenital tracheal stenosis

Objective To evaluate slide tracheoplasty for congenital tracheal stenosis. Methods Between August 2001 and October 2010, twenty-one patients with congenital tracheal stenosis were repaired. The operative age was 28d～8. 6y (mean 21.9 ± 27. 1m) and the weight was 4. 2～22. 5kg (mean 9. 65 ± 4.24 kg) . Except for one case of mediasternal tumour and another one of tracheal trauma, all the restothers had congenital heart disease. There were 9 patients with short tracheal stenosis and 12 patients with long segment tracheal stenosis. The congenital heart disease were repaired underwent low temperature and cardiopulmonary bypass, and the tracheal stenosis were corrected simultaneously. Nine patients with long segment tracheal stenosis were repaired by slide tracheoplasty. Results There was two death in this group. One patient with right and left broncheal stenosis was repaired by synthetic patch. He succumbed 3 months later due todied of granulation tissue on the patch. Another patient with long segment tracheal stenosis was repaired by slide tracheoplasty, who also died from granulation tissue. All other 19 patients were uneventful. These patients were followed up from 2 month to 8 years, there were no complication. CT scan shows that the tracheal anastomosis was patent withand no any stenosis. Conclusions The slide tracheoplasty was used by autologous material,maintaining its contour and function of respiratory epithelium, and keeping its growth. The slide tracheoplasty is best way for correction of long segment tracheal stenosis. Long term follow up is required. Key words: Tracheal stenosis;  Tracheal diseases;  Thoracic surgical procedures
