title: Comparison of outcomes after single and bilateral lung transplantation for obstructive lung disease.
abstract: METHODS
  To determine the long-term functional outcome for single versus bilateral lung transplant for nonseptic obstructive lung disease, we compared the results from 39 single and nine bilateral lung transplant procedures. The nine bilateral lung transplants included three en bloc double lung and six bilateral sequential lung transplants.
  
  
  RESULTS
  Early deaths within 30 days of transplantation occurred in two of nine (22%) bilateral and 4 of 39 (10%) single lung transplants (p = Not significant). Compared with pretransplant values, pulmonary function as assessed by the spirometric indexes of the percent predicted forced vital capacity, forced expiratory volume in one second, forced expiratory volume in one second/forced vital capacity, and forced expiratory flow at 25% and 75% of forced vital capacity improved significantly up to at least 12 months after transplantation for both single and bilateral lung transplant recipients. The degree of pulmonary function improvement was better in single as compared with bilateral lung recipients. By 6 months after transplantation, all but one single and all bilateral lung recipients were in New York Heart Association class I or II (p = Not significant). One-year survival was significantly better after single (77%) compared with after bilateral lung transplantation (35%) (p < 0.05).
  
  
  CONCLUSIONS
  These results suggest that single lung transplantation is the procedure of choice for patients with nonseptic obstructive lung disease.
