概括

这项研究修改了罗斯手术,在17名患者中使用主要肺动脉作为大动脉根管. 这种技术对复杂的大动脉病具有前景,具有出色的初始膜功能,没有血栓塞栓事件.

科学领域:

  • 心血管外科心血管外科
  • 胸部外科手术 胸部外科手术
  • 心脏门手术 心脏门手术

背景情况:

  • 罗斯手术,涉及肺自身移植转移到大动脉位置,是一个成熟的技术.
  • 扩展到患有大动脉根病或狭窄环的患者是有限的.
  • 复杂的大动脉病理需要替代导管.

研究的目的:

  • 评估使用主要肺动脉作为大动脉根管道的可行性和早期结果.
  • 评估冠状动脉骨重新植入肺干的情况.
  • 为了确定复杂的大动脉病患者的疗效.

主要方法:

  • 17名患者 (2-62岁) 使用主要肺动脉及其门进行了主动脉根置换.
  • 冠状动脉骨头被重新植入肺干.
  • 右心室外流通道重建使用冷保存的大动脉或肺移植.

主要成果:

  • 发生了三起外科手术后死亡,所有死亡都归因于出血.
  • 手术后心声图显示了出色的膜功能.
  • 在不服用抗凝药的患者中没有观察到血栓栓塞发作 (除了三例阿司匹林).

结论:
