一种新的低温氧化输液 (HOPE) 系统改善了心脏死亡 (DCD) 后捐赠肝脏的结果. 新的HOPE S3系统显著提高了肝脏存活率和减少损伤,为挽救受损的DCD肝移植提供了一个有希望的解决方案.

科学领域:

  • 移植免疫学 移植免疫学
  • 器官的保存 器官的保存
  • 手术方面的创新.

背景情况:

  • 机器输液是保存心脏死亡 (DCD) 后捐赠的肝移植的关键策略.
  • 严重的热性缺血性损伤对DCD肝移植的活力构成重大风险.
  • 需要新的输液技术来减轻这些风险并改善移植结果.

研究的目的:

  • 开发和验证一种新的机器 perfusion 系统,用于挽救严重的 DCD 肝移植.
  • 评估新系统在缓解与DCD肝脏相关的风险因素方面的有效性.
  • 将新系统的性能与传统方法和静态冷藏相比较.

主要方法:

  • 开发一种具有心脏循环模拟的新型低温氧化 perfusion (HOPE) 系统 (HOPE S3).
  • 在老鼠模型中使用健康肝脏与HTK溶液和DCD肝脏与60分钟热缺血的评估.
  • 通过宏观,显微,分子分析和正管肝移植 (OLT) 来评估结果.

主要成果:

  • 通过HOPE透的DCD肝脏显示损伤减少和生存率改善,而不是在温暖缺血后静态冷藏.
  • 新的HOPE S3系统在60分钟的热性缺血后实现了67%的动物存活率.
  • HOPE S3 保护免受肝细胞和非帕伦基马细胞损伤,增强了微循环和保存了形态.
