概括
远距离的辐射接入 (DRA) 与传统的跨辐射接入 (TRA) 相比,在ST升高心肌梗塞 (STEMI) 的穿皮冠状动脉干预 (PCI) 后显著减少辐射动脉封闭 (RAO). 此外,DRA还导致了更短的静血时间和更少的血液瘤.
科学领域:
- 心脏病学 心脏病学
- 干预心脏病学 干预心脏病学
- 血管接入 血管接入
背景情况:
- 透射接入 (TRA) 是穿皮冠状动脉干预 (PCI) 的标准,但远端辐射接入 (DRA) 不太常见.
- 在预防放射性动脉封闭 (RAO) 方面,DRA可能具有优势.
- 这项研究评估了在接受初级PCI的ST升高心肌梗塞 (STEMI) 患者中DRA和TRA之间的RAO发生率.
研究的目的:
- 为了比较放射性动脉封闭 (RAO) 的发生率,在STEMI患者的初级PCI后24小时.
- 评估二次结果,包括程序时间和与访问相关的并发症.
主要方法:
- 这是一项前性随机对照试验,涉及520名STEMI患者.
- 患者被随机分配到远端辐射接入 (DRA) 或常规超辐射接入 (TRA) 中.
- 在PCI后24小时,通过多普勒超声波评估放射性动脉封闭 (RAO).
主要成果:
- 与DRA (1.9%) 相比,RAO的发病率明显较低 (8.5%) (P=0.001).与DRA相比,RAO的发病率明显较低 (P=0.001).
- DRA与更短的血液静止时间和较低的显著血瘤发病率相关 (mEASY ≥ II).
- 接入成功率很高 (94.6%),光镜时间或辐射剂量没有显著差异.
结论:
- 在STEMI患者的初级PCI后24小时内,远端辐射接入 (DRA) 在预防RAO方面优于传统的跨辐射接入 (TRA).
- DRA提供了减少血液静止时间和降低血瘤率的好处.
- 在STEMI的初级PCI中,DRA是放射性动脉接入的安全有效替代方案.

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.

01:12Arteries of the Upper Limbs
333
The subclavian artery transitions into the axillary artery as it exits the chest and enters the axillary region. This artery is critical for supplying blood to the shoulder area, including the head of the humerus, through the humeral circumflex arteries. As the vessel continues into the upper arm or brachium, it becomes the brachial artery. This artery plays a key role in vascularizing the brachial region and bifurcates at the elbow into several branches. These branches include the deep...
