概括
放射性动脉穿孔 (RAP) 在跨放射性冠状动脉干预 (TRI) 期间不常见,发生在不到1%的病例中. 光学连贯断层扫描 (OCT) 揭示了特征性图案,大多数穿孔是小的和自我密封的.
科学领域:
- 心血管干预 心血管干预
- 医疗成像医学成像
- 血管外科 血管外科
背景情况:
- 通过光学连贯断层扫描 (OCT) 可视化的放射性动脉穿孔 (RAP) 模式需要进一步的表征.
- 这项研究解决了在临床实践中使用OCT建立RAP模式的缺乏问题.
研究的目的:
- 通过术后光学连贯断层扫描 (OCT) 观察到的辐射动脉穿孔 (RAP) 模式的识别和描述.
- 建立跨辐射冠状动脉干预 (TRI) 后的RAP的特征性OCT发现.
主要方法:
- 在经过OCT指导的透射冠状动脉干预 (TRI) 后接受放射性动脉 (RA) OCT的1936名患者的回顾性分析.
- 收集了RAP站点,尺寸 (长度,宽度,弧度) 的数据,并将穿孔分类为小 (弧度≤90°) 或大.
- 利用术后的OCT和放射性动脉血管学 (RAA) 进行RAP识别和评估.
主要成果:
- 辐射动脉穿孔发生在0.83% (16/1936) 的患者中.
- 平均RAP尺寸:距离骨30.6毫米,长1.55毫米,宽0.74毫米,弧度42.5度.
- 87.5%的RAP是小的 (弧 ≤90°),93.7%是自发或通过压缩密封的.
结论:
- 放射性动脉穿孔 (RAP) 是TRI期间不常见的并发症.
- 海外国家和地区提供了独特的模式来描述RAP.
- 大多数RAP是小的,并通过导管吸管进行自发密封.

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.
