与单个内部乳腺动脉 (SIMA) 移植相比,双边内部乳腺动脉 (BIMA) 移植减少了重复冠状动脉再血管化的需要. 这种改善的长期存活率和降低的复血管化风险表明,在冠状动脉旁路移植中,应更频繁地考虑使用BIMA.
科学领域:
- 心血管外科
- 胸部手术
- 血管外科
背景情况:
- 冠状动脉旁路移植 (CABG) 是治疗冠状动脉疾病的关键手术.
- 与单个内部乳腺动脉 (SIMA) 导管相比,双边内部乳腺动脉 (BIMA) 导管的长期存活率更高.
- 在BIMA与SIMA移植后重复血管化的数据较少.
研究的目的:
- 通过BIMA对患者进行CABG的频率,时间和重复冠心血管化的类型进行比较.
- 评估与BIMA和SIMA移植相关的长期结果,以重血管化和存活为准.
主要方法:
- 在1992年至2014年间对47,984次心血管外科手术进行了多中心的回顾性分析.
- 进行倾向匹配分析,将接受BIMA的1297名患者与接受SIMA的1297名患者进行比较.
- 主要终点:没有重复冠状动脉再血管.
主要成果:
- BIMA移植与明显更高的重复血管化无关 (HR,0. 78;P=0. 009).
- 在BIMA患者中,重复血管化发生在15. 1%,而在SIMA患者中,这一比例为19. 4% (P=0. 004).
- 在12年内,BIMA移植也减少了全因死亡率 (HR,0. 79;P=0. 001),但没有增加住院发病率.
结论:
- 双边内部乳腺动脉移植与重复血管化的风险降低有关.
- 在冠状动脉旁路移植后,BIMA移植改善了长期生存.
- 在CABG过程中应增加对BIMA导管的考虑.
