    Summary
    Objective: The limited number of available grafts is one of the major obstacles of lung transplantation. Size-reduced lung transplantation allows the use of oversized grafts for small recipients. Optimal lung size matching is vital to achieve best functional outcome and avoid potential problems when using oversized grafts. We hypothesise that donor-predicted postoperative forced expiratory volume in 1s (ppoFEV1) correlates with the recipient best FEV1 after size-reduced lung transplant, being useful for the estimation of function outcome. Methods: All patients undergoing size-reduced or standard bilateral lung transplantation were included (1992-2007). Donor ppoFEV1 was calculated and corrected with respect to size reduction and correlated with recipient measured best FEV1 post-transplant. In addition, pre- and postoperative clinical data including surgical complications and outcome of all size-reduced lung transplant recipients were compared with standard lung transplant recipients. Results: A total of 61 size-reduced lung transplant recipients (lobar transplants, n=20; anatomic or non-anatomic resection, n=41) were included and compared to 145 standard transplants. The mean donor-recipient height difference was statistically significant between the two groups (p=0.0001). The mean donor ppoFEV1 was comparable with recipient best FEV1 (2.7±0.6 vs 2.6±0.7 l). There was a statistically significant correlation between donor ppoFEV1 and recipient best FEV1 (p=0.01, r=0.688). The 30-day mortality rate and 3-month, 1- and 5-year survival rates were comparable between the two groups. Conclusions: In size-reduced lung transplantation, postoperative recipient best FEV1 could be predicted from donor-calculated and corrected FEV1 with respect to its size reduction. Compared to standard lung transplantation, equivalent morbidity, mortality and functional results could be obtained after size-reduced lung transplantation
