肺移植受者预后关键影响因素及改善策略

Key influencing factors and improvement strategies of prognosis in lung transplant recipients

  • 摘要: 近年来,肺移植在供者评估、围手术期支持与免疫调控等方面取得了显著进展,为改善受者长期生存奠定了基础。扩大标准供肺的合理应用及离体肺灌注技术的推广,提高了边缘供肺的利用效率与安全性;对供者吸烟史、感染状况等风险因素的精细化评估,降低了原发性移植物失功及术后感染发生率。在受者管理方面,个体化评估逐渐完善,术中体外膜肺氧合的规范化应用和微创手术技术的发展有效减少了围手术期损伤;术后免疫抑制方案的优化以及排斥反应监测技术的进步,进一步提升了移植物长期存活。然而,慢性移植物失功及反复或难治性感染仍是制约远期预后的主要瓶颈。未来研究需聚焦扩大供体来源、提升边缘供肺修复质量、推进精准免疫抑制与抗感染策略,系统提升受者长期生存率与生活质量。

     

    Abstract: In recent years, remarkable advances have been made in lung transplantation regarding donor evaluation, perioperative support, and immune regulation, laying a foundation for improving the long-term survival of recipients. The rational application of extended criteria donor lungs and the popularization of ex vivo lung perfusion technology have enhanced the utilization efficiency and safety of marginal donor lungs. Refined assessment of risk factors such as donors’ smoking history and infectious status has reduced the incidence of primary graft dysfunction and postoperative infection. In terms of recipient management, individualized assessment systems have been gradually optimized. The standardized application of intraoperative extracorporeal membrane oxygenation and the development of minimally invasive surgical techniques have effectively alleviated perioperative injuries. The optimization of postoperative immunosuppressive regimens and advances in rejection monitoring technologies have further improved the long-term survival of grafts. Nevertheless, chronic graft dysfunction and recurrent or refractory infections remain the major bottlenecks restricting long-term prognosis. Future research should focus on expanding donor sources, improving the repair quality of marginal donor lungs, promoting precise immunosuppression and anti-infection strategies, and comprehensively enhancing the long-term survival rate and quality of life of lung transplant recipients.
