Lung Transplantation for Non-Cystic Fibrosis Bronchiectasis: Analysis of a 13-Year Experience

Abstract

Lung transplantation is a well-established treatment for end-stage cystic fibrosis, and there are considerable data on medium- and long-term results. However, less information exists about transplantation for non-cystic fibrosis bronchiectasis. Between December 1988 and June 2001, 22 patients (12 men, 10 women) underwent transplantation for bronchiectasis not due to cystic fibrosis. Procedures were bilateral sequential single-lung transplants (BSSLTX) in 4 patients, en bloc double lung transplants (DLTX) in 5, heart-lung transplants (HLTX) in 6, and single-lung transplants (SLTX) in 7. Lifelong outpatient follow-up was continued at a minimum of every 6 months. One-year Kaplan-Meier survival for all patients was 68% (95% confidence interval [CI], 54%-91%), and 5-year survival was 62% (95% CI, 41-83%). One-year survival after SLTX was 57% (95% CI, 20%-94%) vs 73% (95% CI, 51-96%) for those receiving 2 lungs. At 6 months, mean forced expiratory volume in 1 second was 73% predicted (range, 58%-97%), and mean forced vital capacity was 68% predicted (range, 53%-94%) after receiving 2 lungs (n = 10); in the SLTX group at 6 months, mean forced expiratory volume in 1 second was 50% predicted (range, 34%-61%), and mean forced vital capacity was 53% predicted (range 46-63%) (n = 4). Survival and lung function after transplantation for non-cystic fibrosis bronchiectasis was similar to that after transplantation for cystic fibrosis. A good outcome is possible after single lung transplantation in selected patients.
