概括
与传统的跨辐射接入 (TRA) 相比,远距离跨辐射接入 (dTRA) 在穿皮冠状动脉干预 (PCI) 后显著减少辐射动脉封闭 (RAO). 这种方法还可以缩短血液静止的时间,而不会影响手术的成功.
科学领域:
- 心脏病学 心脏病学
- 血管外科 血管外科
- 干预心脏病学 干预心脏病学
背景情况:
- 超辐射接入 (TRA) 是冠状动脉干预的标准,由于降低出血风险和更好的患者舒适性.
- 放射性动脉封闭 (RAO) 限制了放射性动脉在未来的手术中重新使用.
- 远距离透射接入 (dTRA) 被研究以降低RAO,同时保持程序有效性.
研究的目的:
- 评估远端透射接入 (dTRA) 与传统透射接入 (TRA) 相比,是否可以减少早期和中期的辐射动脉封闭 (RAO).
- 评估dTRA对手术成功,血液静止时间,辐射暴露和手/手腕功能的影响,在接受皮肤冠状动脉干预 (PCI) 的患者中.
主要方法:
- 一个单中心,前性,随机优势试验包括426名接受选择性PCI的患者.
- 患者被分为1:1的dTRA (n=213) 或TRA (n=213).
- 放射性动脉封闭 (RAO) 被评估使用双重超声波在手术后24小时和30天.
主要成果:
- 24小时RAO率在dTRA组 (0.5%) 与TRA组 (8.7%;p<0.001) 相比显著较低.
- 在30天后,RAO与dTRA (1.6%) 相比,与TRA (8.2%;p<0.001) 相比,RAO仍然明显较低.
- 与dTRA (3.0小时) 相比,dTRA (3.0小时) 与TRA (6.0小时;p<0.001) 的中位血液静止时间较短,手术成功和辐射暴露相似.
结论:
- 与选择性PCI中TRA相比,远距离透射接入 (dTRA) 显著降低RAO发生率,缩短血液静止时间.
- dTRA不会影响程序的成功或增加辐射暴露.
- 这些发现支持dTRA在冠状动脉干预中常规采用,早期手部功能略有改善.

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:

Peripheral Artery Disease (PAD) is characterized by narrowed arteries that diminish blood flow to the extremities. Effective management of PAD requires an interprofessional approach involving various healthcare professionals. The critical aspects of interprofessional care for PAD patients focus on risk factor modification, drug therapy, exercise therapy, nutrition therapy, critical limb ischemia care, and interventional radiology and surgical procedures.The primary treatment goal for PAD...
