[Update: Organ Donation and Preservation]

Area of Science:

• Cardiovascular & Pulmonary Medicine
• Transplantation Biology
• Surgical Innovation

Background:

• Lung transplantation faces challenges due to donor lung shortages and preservation limitations.
• Advancements in organ preservation and donation strategies are crucial for improving patient outcomes.
• Marginal donor lungs and extended preservation times remain significant areas for research.

Purpose of the Study:

• To review recent innovations in organ donation and donor lung preservation.
• To highlight the impact of normothermic ex vivo lung perfusion (EVLP), donation after circulatory death (DCD), and hypothermic preservation on lung transplantation.
• To summarize the current state of knowledge on optimizing donor lung utilization and viability.

Main Methods:

• Review of key advancements in lung transplantation technologies and strategies.
• Analysis of the role of normothermic ex vivo lung perfusion (EVLP) in donor lung assessment and rehabilitation.
• Examination of donation after circulatory death (DCD) protocols and outcomes.
• Evaluation of controlled hypothermic preservation at 10°C for extended lung viability.

Main Results:

• Normothermic ex vivo lung perfusion (EVLP) enables the use of high-risk donor lungs, improving transplantation outcomes.
• Donation after circulatory death (DCD) provides a comparable alternative to traditional donation, addressing donor shortages.
• Controlled hypothermic preservation at 10°C extends preservation times and offers greater scheduling flexibility.

Conclusions:

• EVLP, DCD, and controlled hypothermic preservation represent significant progress in lung donation and preservation.
• These innovations expand the donor pool and enhance the feasibility and success of lung transplantation.
• Future research and clinical integration of these techniques are expected to further revolutionize lung transplantation standards.
