ObjectiveEx vivo lung perfusion (EVLP) is reportedly a useful strategy that permits marginal donor lungs to be evaluated and reconditioned for successful lung transplantation (LTx). This systematic review and meta-analysis was performed to evaluate the outcomes of EVLP conducted for marginal donor lungs.MethodsWe searched PubMed, the Cochrane Library, and Embase to select studies describing the results of LTx following EVLP for marginal donor lungs compared with standard LTx without EVLP. We performed a meta-analysis to examine donor baseline characteristics, recipient baseline characteristics, and postoperative outcomes.ResultsOf 1380 studies, 8 studies involving 1191 patients met the inclusion criteria. Compared with the non-EVLP group (ie, standard LTx without EVLP), the EVLP group (ie, EVLP of marginal donors following LTx) had similar donor age and sex and recipient baseline age, sex, body mass index, bridge by ventilator/extracorporeal life support/extracorporeal membrane oxygenation, and rate of double LTx but more abnormal donor lung radiographs (P = .0002), a higher smoking history rate (P = .03), and worse donor arterial oxygen tension/inspired oxygen fraction (P < .00001). However, there were no significant differences in outcomes between the EVLP and non-EVLP groups with respect to the length of postoperative intubation, postoperative extracorporeal life support/extracorporeal membrane oxygenation use, length of intensive care unit stay, length of hospital stay, 72-hour primary graft dysfunction of grade 3, 30-day survival, or 1-year survival (all P values > .05).ConclusionsPosttransplant outcomes were similar between EVLP-treated LTx and standard LTx without EVLP, although the quality of donor lungs was worse with EVLP-treated LTx.Copyright © 2019 The American Association for Thoracic Surgery.
