title: Single lung transplantation followed by contralateral bullectomy for bullous emphysema.
abstract: METHODS
  Single lung transplantation for emphysema is now standard practice despite initial concerns, including the possibility that the compliant diseased lung would compress the transplanted lung as a result of hyperinflation. We describe a patient with severe bilateral bullous emphysema and alpha-1-antitrypsin deficiency who underwent single lung transplantation after which hyperinflation of the native lung led to significant compression of the pulmonary allograft. The patient subsequently underwent bullectomy of the contralateral lung with marked improvement in his functional status.
  
  
  RESULTS
  After bullectomy, the patient's forced expiratory volume in 1 second increased from 1.77 to 2.82 L, his total lung capacity fell from 7.23 to 6.19 L, and his 6-minute walk increased from 724 to 1269 feet. However, 7 months after bullectomy, there was evidence that the bullous disease in the native lung was recurring.
  
  
  CONCLUSIONS
  Significant hyperinflation of the native lung with compromise of the pulmonary allograft can occur after single lung transplantation for bullous emphysema. Bullectomy of the diseased lung after transplantation improved allograft function in our patient. Alternatively, bilateral lung transplantation for severe bilateral bullous emphysema may be considered.
