Background: The outcomes of lung transplantation (LT) are well known in developed countries, but not in Latin America. Our objective was to report the LT experience at a single center in Argentina.
Methods: From June 1994 to February 2003, the 54 LT that were performed included 36 single-lung transplants SLT (45.5%) and 18 double-lung transplants (DSLT) (22.7%). Indications for SLT (n = 36) were emphysema (n = 23) and pulmonary fibrosis (n = 13); for DSLT (n = 18), bronchiectasis (n = 8), cystic fibrosis (n = 8), pulmonary emphysema (n = 1), and bronchiolitis obliterans syndrome caused by graft-versus-host disease after bone-marrow transplantation (n = 1). A univariate analysis, chi-square test with Yates' correction was used for qualitative variables; Wilcoxon-Mann-Whitney test, for quantitative and ordinal variables. Survivals were estimated by the Kaplan-Meier method.
Results: In-hospital mortality (HM) was 21.1%. Among SLT, early death was due to sepsis in six patients and by ischemia-reperfusion injury (IRI) and acute rejection in other two. In DSLT, two patients died due to IRI and one, sepsis. The overall estimated survival rates at 1, 2, and 4 years were 70.1% +/- 6.5%, 54.3% +/- 7.2%, and 44.3% +/- 7.9%, respectively. The median overall survival was 26.5 (10 to 34) months. When HM was excluded, survival at 4 years was 51.3% +/- 8.7%. The estimated survival at 3 years was 43.3% +/- 9.3% for SLT and 58.7% +/- 13% for DSLT (P = 6). Survival differences according to the baseline diagnosis were not significant (P =.6). Median follow-up time (percentiles 25 to 75) was 16 (2 to 27) months.
Conclusions: Our LT program shows similar results to those reported by the International Society for Heart and Lung Transplantation for developed countries.
