Abstract

Background: Primary graft dysfunction (PGD) is a severe, acute and post-transplantation lung injury associated with early morbidity and mortality. We aimed to identify clinical risk factors for PGD, as well as the outcome of PGD after lung transplantation in Korea.Methods: We retrospectively analyzed lung transplant patients in a South Korean Hospital. The primary outcome was grade 3 PGD, defined according to the International Society for Heart and Lung Transplantation criteria. We compared grade 0-2 PGD group to grade 3 PGD group to identify the risk factors and outcome of grade 3 PGD.Results: Sixty-one patients were enrolled; 16 (26.2%) developed grade 3 PGD. Univariate analysis revealed higher body mass index (BMI) and history of smoking, extracorporeal membrane oxygenation (ECMO) before transplantation in recipients, and an extended intraoperative ischemic time as risk factors for grade 3 PGD. In multivariate analysis, independent risk factors for PGD were higher BMI in recipients [odds ratio(OR), 1.286; P=0.043] and total intraoperative ischemic time (OR, 1.028; P=0.007). As compared to grade 0-2 PGD, grade 3 PGD was significantly associated with a higher re-operation rate (grade 0-2 PGD vs. grade 3 PGD, 22.2% vs. 50.0%; P=0.036), prolonged ventilator apply (median: 6.0 vs. 14.5 days; P=0.044), a longer intensive care unit stay (median: 9.0 vs. 17.0 days; P=0.041), and a higher rate of renal replacement therapy (RRT) (17.8% vs. 62.5%; P=0.002) after transplantation.Conclusions: Patients who developed grade 3 PGD had higher re-operation rate, longer ventilator apply,longer intensive care unit stay, higher rate of RRT, with higher BMI and total intraoperative ischemic time being the significant risk factor. These findings may allow physicians to modify risk factors before development of PGD.
