title: The role of adjunctive procedures in reducing postoperative tracheobronchial obstruction in single lung patients with congenital tracheal stenosis undergoing slide tracheoplasty.
abstract: OBJECTIVE
  Congenital tracheal stenosis (CTS) and a single right lung treated with slide tracheoplasty (ST) has relatively high rates of mortality and morbidity. We report a single institution's experience with adjunctive procedures at the time of ST to reduce postoperative tracheal obstruction in patients with a single right lung and CTS.
  
  
  METHODS
  With IRB approval, 8 patients with a single right lung and CTS who underwent ST in our institution between 2008 and 2016 were reviewed.
  
  
  RESULTS
  Seven of 8 patients (88%) survived, with a median follow-up period of 35 (3-89) months. The only mortality was because of complications unrelated to the airway. Six of 8 patients underwent ST anterior to the aortic arch (tracheal translocation, TT). This was combined with tracheopexy concomitantly in 3 patients and subsequently in one patient. Two patients had insufficient tracheal length for TT. Both underwent aortopexy. Of three patients undergoing TT with tracheopexy concomitantly, two have been successfully extubated, and a third has required tracheostomy for subglottic stenosis. All patients undergoing TT without tracheopexy have experienced severe tracheobronchomalacia.
  
  
  CONCLUSIONS
  We conclude that adjunctive TT with tracheopexy might be associated with lower rates of tracheobronchial obstruction in patients with a single right lung undergoing ST for CTS.
