Redo lung transplantation for acute and chronic lung allograft failure: long-term follow-up in a single center.

Objective: This study was undertaken to evaluate outcomes of redo lung transplantation (LT) for acute and chronic graft failure.

Methods: Between 1988 and 2007, 388 LT procedures were performed on 369 patients. From those, 17 (4.6%) patients had redo LT once and 2 patients had redo LT twice. Patient survival and recurrence of bronchiolitis obliterans syndrome (BOS) after redo LT were reviewed.

Results: The overall survival rates of the 17 redo LT recipients at 1, 2 and 5 years were 59+/-23%, 59+/-23% and 42+/-25%, respectively. For the chronic graft failure group (n=12), survival rates at 1, 2 and 5 years were 67+/-26%, 67+/-26% and 44+/-30%, respectively. These survival rates were significantly lower than the survival rates observed in our experience after primary LT (n=352, 1-, 2- and 5-year survival rates of 88+/-4%, 80+/-4% and 65+/-5%, respectively. For the acute graft failure group (n=5), the 1-year survival rate was 40%; two patients remain free from BOS. Two patients had a second redo LT, one died from multi-organ failure on postoperative day 86 and the other died from pulmonary aspergillosis on postoperative day 214.

Conclusions: Redo LT is a valid therapeutic option for selected patients with BOS and might be an option for highly selected patients with acute lung graft failure. Outcomes from a second redo LT are poor, and a second lung retransplantation must be used very cautiously, if at all.
