Lung Transplant
Conditions
Brief summary
The study population will be patients with planned double-lung transplant, with preoperative ex-vivo reconditioning procedure. The ex-vivo procedure will be performed for lungs considered as limit to be directly implanted according to the national classification or in case of Maastrich 3 decision. They required a rehabilitation procedure like ex-vivo to determine their quality. Once the procedure initiated, the unused remaining liquid will be retrieved for the first gasometry usually performed. This will be the time T1 of sampling. The unused remaining liquid will be retrieved for the gasometry of end of procedure usually performed, before the graft cooling. This will be the time T2. The purge liquid of first lung at the declamping of the pulmonary artery will be retrieved at the time of unclamping (time T3 of sampling). The purge liquid of the second lung at the declamping of the pulmonary artery will be retrieved with the same procedure (time T4 of sampling). The samples will be analysed with ELISA technique. The endothelial dysfunction will be evaluated with plasma concentration of heparan sulphate, syndecan-1, endothelin-1 and i-NOS.
Interventions
OTHERPlasma concentration analysis during and after ex-vivo pulmonary reconditioning
The pulmonary endothelial dysfunction will be evaluated with plasma concentration of heparan sulphate, syndecan-1, endothelin-1 and i-NOS.
