概括
超辐射次要接入 (TR-SA) 与传统的股骨次要接入 (TF-SA) 相比,在跨导管大动脉置换 (TAVR) 期间显著降低了血管并发症和严重出血. TR-SA提供了一个更安全的替代方案,TF-SA的并发症是10倍高.
科学领域:
- 心血管干预 心血管干预
- 血管接入技术 血管接入技术
- 通过导管进行大动脉替换 (TAVR)
背景情况:
- 在TAVR过程中探索跨辐射二次接入 (TR-SA) 作为传统的股骨二次接入 (TF-SA) 的替代方案,用于在TAVR过程中放置猪尾导管.
- 评估TR-SA与TF-SA对于优化TAVR中患者安全和程序结果至关重要.
研究的目的:
- 在接受TAVR的患者中,评估和比较TR-SA和TF-SA之间的二次访问相关血管并发症的发生率.
- 确定TR-SA作为TAVR程序中的二次访问策略的安全性和有效性.
主要方法:
- 从PULSE注册表中对10120名接受了输血骨TAVR (2016-2021) 的患者进行了回顾性分析.
- 在TR-SA (n=1,686) 和TF-SA (n=7,165) 组之间的血管并发症率的比较,通过1:1倾向性得分匹配进行验证.
- 使用Valve学术研究联盟3定义评估的结果.
主要成果:
- 与TF-SA相比,TR-SA显示了与二次接入相关的血管并发症率 (0.3%与3.2%,P<0.001) 和主要并发症 (0.2%与1.5%,P<0.001) 的显著降低 (0.3%与3.2%,P<0.001).
- 严重出血 (III/IV型) 在TR-SA患者中较少 (2.5%对4.7%,P<0.001),并且没有TR-SA患者需要手术修复,而TF-SA患者中只有0.9%.
- 倾向性得分匹配证实TR-SA的二次访问并发症率较低 (0.2%对2.9%,P<0.001).
结论:
- 与TF-SA相比,TR-SA与输血性TAVR期间的进入部位并发症和严重出血率相对较低.
- 与TF-SA相关的二次访问相关的并发症是TF-SA的10倍,往往需要侵入性干预.
- 这些发现表明,应该更广泛地考虑TR-SA,挑战TF-SA在TAVR程序中的当前流行.

Assessment of Radial Pulse
The radial pulse, located at the wrist, is often the preferred site for assessing peripheral pulse because of its accessibility and dependability. The process of determining the radial pulse involves several steps:

Apical-Radial (A-R) Pulse Assessment
The A-R pulse assessment involves simultaneous evaluation of the apical and radial pulses. When the apical and radial pulse rates vary, this assessment helps identify a pulse deficit.
