概括
放射性动脉作为复合移植用于全动脉再血管化 (TAR),需要平均长度为18.02厘米才能到达右冠状动脉 (RCA) 远端分支. 较短的辐射动脉移植可能需要额外的导管来进行完整的再血管化.
科学领域:
- 心血管外科心血管外科
- 手术创新 在外科创新.
- 冠状动脉绕道移植冠状动脉绕道移植
背景情况:
- 整体动脉复血管化 (TAR) 与传统的旁路移植相比,具有优势.
- 使用放射性动脉作为复合移植,可以避免大动脉操纵.
- 这种技术的主要局限性是达到远距离目标所需的移植长度.
研究的目的:
- 评估使用放射性动脉作为TAR复合移植的可行性.
- 为了确定射线动脉达到远端右冠状动脉 (RCA) 分支所需的长度.
- 在复合结构中分析影响放射性动脉移植长度的因素.
主要方法:
- 预期收集来自169名接受放射性动脉复合移植治疗的患者的数据.
- 测量辐射动脉的长度,瘤的数量和移植流量.
- 患者人体测量和目标血管位置与移植长度的相关性.
主要成果:
- 所需的平均辐射动脉长度为18.02厘米.
- 短于15.9厘米的辐射动脉移植通常需要用另一条导管进行延伸.
- 在T-配置中,每次顺序解剖需要额外的0.53厘米的辐射动脉长度.
结论:
- 平均辐射动脉长度为18.02厘米,足以将复合接种到偏远的RCA目标.
- 放射性动脉复合体移植的T-配置需要仔细的长度规划.
- 这种策略是可行的,但必须考虑移植长度,以获得全动脉再血管化的最佳结果.

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:

01:12Arteries of the Upper Limbs
623
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...

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.
