This article reviews recent developments in the selection, assessment, and management of the potential lung donor that aim to increase donor organ use. The scarcity of suitable donor organs results in long waiting times and significant mortality for those patients awaiting transplant. Strategies to expand the donor pool can substantially improve donor lung use rates. Although further long-term studies are required to confirm that long-term outcomes are not being compromised, the available evidence suggests that the traditional factors defining a lung as marginal or extended do not actually compromise outcomes within the framework of current donor management strategies.

Immunosuppressive therapy has contributed significantly to improved survival after solid organ transplantation. Nevertheless, treatment-related adverse events and persistently high risk of chronic graft rejection remain major obstacles to long-term survival after lung transplantation. The development of new agents, refinements in techniques to monitor immunosuppression, and enhanced understanding of transplant immunobiology are essential for further improvements in outcome. In this article, conventional immunosuppressive regimens, novel approaches to preventing graft rejection, and investigational agents for solid organ transplantation are reviewed.

There are 6 major types of airway complications following lung transplantation: necrosis and dehiscence, infection, granulation tissue formation, malacia, fistulae, and stenosis. This article reviews the risk factors for developing airway complications after lung transplantation, the clinical features of the complications, and treatment options for these problems.

ReviewNovel approaches to expanding the lung donor pool: donation after cardiac death and ex vivo conditioning.
Two novel approaches have been developed to potentially increase the availability of donor lungs for lung transplantation. In the first approach, lungs from donation after cardiac death (DCD) donors are used to increase the quantity of organ donors. In the second approach, a newly developed normothermic ex vivo lung perfusion (EVLP) technique is used as a means of reassessing the adequacy of lung function from DCD and from high-risk brain death donors prior to transplantation. This EVLP technique can also act as a platform for the delivery of novel therapies to repair injured organs ex vivo.

Review Historical ArticleExtracorporeal life support as a bridge to lung transplantation.
Patients who are excellent candidates for lung transplantation often die on the waiting list because they are too sick to survive until an organ becomes available. Improvements in lung transplant outcomes, patient selection, and artificial lung device technologies have made it possible to bridge these patients to successful life-saving transplantation. Extracorporeal life support (ECLS) should be tailored to minimize morbidity and provide the appropriate mode and level of cardiopulmonary support for each patient's physiologic requirements. Novel device refinements and further development of ECLS in an ambulatory and simplified manner will help maintain these patients in better condition until transplantation.
