Ex vivo lung perfusion; this idea deserves testing

Ex vivo lung perfusion in Brazil

OBJECTIVE To evaluate the use of ex vivo lung perfusion (EVLP) clinically to prepare donor lungs for transplantation. METHODS A prospective study involving EVLP for the reconditioning of extended-criteria donor lungs, the criteria for which include aspects such as a PaO2/FiO2 ratio < 300 mmHg. Between February of 2013 and February of 2014, the lungs of five donors were submitted to EVLP for u...

Ex vivo lung perfusion: initial Brazilian experience* Perfusão pulmonar ex vivo: experiência nacional inicial

In the last 20 years, lung transplantation has become the standard treatment for patients with end-stage lung disease. However, less than 20% of the donor lungs available for transplant are actually usable. This disparity between the growing number of recipients and the small number of donors has resulted in increased mortality among lung transplant candidates on waiting lists. Strategies such ...

Antagonizing reactive oxygen species during ex vivo lung perfusion.

TO THE EDITOR: The stop of flow (ischemia) would be interpreted as membrane depolarization, through the inhibition of KATP channels, leading to activation of NADPH oxidase, leading to increased reactive oxygen species (ROS) production (1). The resultant ROS are claimed to be an effective mediator for ischemic preconditioning (IPC), as proved by the observation that the presence of antioxidants ...

Towards a better understanding of ex vivo lung perfusion.

Ex vivo lung perfusion (EVLP) is probably the most promising technique currently available to substantially increase the number of acceptable donor lungs and to improve the outcome after lung transplantation. Several ongoing prospective single and multicentre trials are currently investigating the potential and the individual advantages of different platforms available for EVLP. So far, a numbe...
