Left pneumonectomy in a patient with a chronically infected allograft.

We describe a young man with cystic fibrosis who underwent bilateral sequential lung transplantation (BSLT) and a subsequent right single-lung re-transplant for bronchiolitis obliterans syndrome (BOS). Destruction of the retained left lung with recurrent pneumonia, worsening bronchiectasis and abscess formation was treated with a left lower lobectomy and a subsequent complete pneumonectomy. The patient tolerated the procedures and is alive and well 18 months after left pneumonectomy. In the setting of BOS, allograft pneumonectomy can be performed safely to remove non-functioning infected tissue.
