Experience of extracorporeal membrane oxygenation as a bridge to lung transplantation in France
2013
Background Extracorporeal membrane oxygenation (ECMO) is increasingly used as a bridge to lung transplantation (LTx). However, data concerning this approach remain limited. Methods We retrospectively reviewed the medical records of all patients in France who received ECMO as a bridge to LTx from 2007 to 2011. Post-transplant survival and associated factors were assessed by the Kaplan-Meier method and the Cox model. Results Included were 36 patients from 11 centers. Indications for LTx were cystic fibrosis (CF) in 20 (56%), pulmonary fibrosis (PF) in 11 (30%), and other diagnoses in 5 (14%). ECMO was venovenous for 27 patients (75%) and venoarterial for 9 (25%). Mean follow-up was 17 months. Bridging to LTx was achieved in 30 patients (83%); however, only 27 patients (75%) survived the LTx procedure, and 20 (56%) were discharged from hospital. From ECMO initiation, 2-year survival rates were 50.4% overall, 71.0% for CF patients, 27.3% for PF patients, and 20.0% for other patients ( p p = 0.04). Conclusions Our study confirms that the use of ECMO as a bridge to LTx in France could provide a medium-term survival benefit for LTx recipients with critical conditions. Survival differed by underlying respiratory disease. Larger studies are needed to further define the optimal use of ECMO.
