OBJECTIVES: Despite progress in lung transplantation (LTx) techniques, a shortage of donor lungs persists worldwide. Ex vivo lung perfusion (EVLP) is a technique that evaluates, optimizes and enables transplantation of the lungs that would otherwise have been discarded. Herein, we present our centre's first EVLP experiences between July 2012 and June 2016, when we performed 149 LTxs.

METHODS: It was a single-centre, retrospective analysis of a prospectively collected database. The EVLP group (n = 9) consisted of recipients who initially received discarded donor lungs that were reconditioned using EVLP. The non-EVLP (N-EVLP) group (n = 18) consisted of data-matched patients receiving conventional quality lungs in the conventional way. Both groups were compared on primary graft dysfunction (PGD) grades 0-3, pulmonary function, chronic lung allograft dysfunction and survival.

RESULTS: In the EVLP group, 33% (3/9) developed PGD1 at 72 h post-LTx. In the N-EVLP group, 11% (2/18) developed PGD1, 6% (1/18) PGD2 and 11% (2/18) PGD3 at 72 h post-LTx. At 3 and 24 months post-LTx, forced expiratory volume in 1 s as percentage of predicted was similar in the EVLP (78% and 92%) and N-EVLP groups (69% and 89%). Forced vital capacity as a percentage of predicted was comparable in the EVLP (77% and 93%) and N-EVLP groups (68% and 101%). Chronic lung allograft dysfunction was diagnosed in 1 N-EVLP patient at 2 years post-LTx. Three-year survival was 78% (7/9) (the EVLP group) vs 83% (15/18) (the N-EVLP group).

CONCLUSIONS: These results are in line with the existing literature suggesting that transplantation of the previously discarded lungs recovered by EVLP leads to equal outcomes compared to conventional LTx methods.
