Outline of Final Research Achievements

Lung transplantation is the only established life-saving treatment for patients with end-stage respiratory diseases, although donor shortage is still a serious problem in all over the world. To expand the donor lung pool, ex vivo lung perfusion (EVLP) has been developed to assess pulmonary function of marginal donor lungs and preserve the donor lungs. However, current lung evaluation and preservation methods during EVLP are imperfect, occasionally resulting in poor outcomes. In this study, we developed an extracorporeal lung preservation system that combine cold preservation and EVLP to realize long-term lung preservation while evaluating lung function in EVLP. In animal experiments using pigs, we demonstrated that long-term preservation of donor lungs is feasible by combining cold preservation of donor lungs and EVLP.

Academic Significance and Societal Importance of the Research Achievements

ドナー肺の長期保存法については、未だ明確な保存法が確立されていない。臨床におけるヒト肺の冷保存時間は、6時間から8時間が限界である。そのため、本研究では、冷保存とEVLPを組み合わせた肺の長期保存法が実現可能な体外肺保存装置を開発し、動物実験で長期間肺機能を保存されることを見出した。本研究成果により、冷保存とEVLPを組み合わせることでドナー肺の長時間保存が可能となる条件を見出す学術的意義を得ることができた。さらに、ドナー肺の保存時間の制限などで廃棄されていたドナー肺の移植活用率の向上、移植待機中の患者の救命症例の増加、肺移植件数の増加に繋がる社会的意義が高い研究成果になりえると考えられる。
