概括
与单个动脉移植相比,多重动脉移植 (MAG) 显著改善了冠状动脉手术后的长期生存率. 然而,MAG的生存益处在使用沙芬静脉移植 (SVG) 时会消失.
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
- 血管外科 血管外科
背景情况:
- 在冠状动脉外科手术中,软静脉移植 (SVG) 对多动脉移植 (MAG) 后的长期存活的影响与单动脉移植对比仍不清楚.
- 在接受冠状动脉旁路移植 (CABG) 的患者中研究 SVG 的作用对于优化手术策略至关重要.
研究的目的:
- 为了确定SVG的使用是否会影响MAG患者的晚期生存,而不是单个动脉移植.
- 评估全动脉再血管化 (TAR) 与用补充静脉移植进行动脉移植的生存益处.
主要方法:
- 一项回顾性,观察性,多中心队列研究,使用澳大利亚和新西兰心脏和胸部外科医生协会数据库 (2001-2020).
- 倾向性得分匹配被用来比较MAG和单个动脉移植队列之间的结果,以及TAR和MAG与SVG队列之间的结果.
- 主要结局是所有原因的晚期死亡,随访时间中位数为5.0年.
主要成果:
- 与单个动脉移植相比,MAG与明显较低的死亡率相关 (HR,0.79;P<0.001).
- 总动脉再血管化 (没有SVG) 与MAG与补充SVG (HR,0.85;P<0.001) 相比,显示了进一步的生存益处.
- 在对SVG存在进行调整后,使用多个动脉的生存优势消失了.
结论:
- 与冠状动脉外科手术中单个动脉移植相比,多重动脉移植显著改善了长期存活率.
- 当不使用沙芬静脉移植时,观察到进一步的增量生存益处,突出显示了全动脉再血管化的优势.

Varicose veins, or varicosities, develop when the valves in the veins, which control blood flow, weaken or damage. It causes blood to pool and the veins to enlarge. Understanding the clinical manifestations, diagnostic approaches, and management options for varicose veins is crucial for effective treatment and relief.Clinical manifestationsClinical manifestations of varicose veins include a heavy, achy feeling or pain after prolonged standing or sitting. This discomfort can often be relieved by...

Hemodialysis I: Introduction
36
Hemodialysis (HD) is a medical treatment that artificially removes waste products, excess fluids, and toxins from the blood when the kidneys are no longer able to perform these functions effectively. In this process, blood is filtered through a semipermeable membrane, allowing for the selective removal of waste while preserving necessary components like blood cells and proteins. Hemodialysis is typically performed in patients with end-stage renal disease (ESRD) or severe kidney...
