Lung transplant at the Favaloro Foundation: a 13-year experience

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.

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.

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.

Our LT program shows similar results to those reported by the International Society for Heart and Lung Transplantation for developed countries.
