这项研究开发了一种用于动脉狭窄的新猪模型,发现开环和闭环支架显示了类似的支架内静止率. 光学连贯性断层扫描 (OCT) 有效地评估了新理想的生长.
科学领域:
- 心血管研究的心血管研究.
- 医疗器械创新 医疗器械创新
- 对疾病的动物建模.
背景情况:
- 动脉狭窄是缺血性中风的一个重要原因.
- 在 carotid 动脉 stenting 后,静脉静脉复缩 (ISR) 是一个临床挑战.
- 猪是研究ISR的一个合适的动物模型.
研究的目的:
- 建立一个新的猪模型,用于动脉静脉静脉静脉静脉静脉静脉静脉静脉静脉静脉 (ISR).
- 为了比较ISR发生率和开环和闭环 carotid支架之间的血管反应.
- 评估光学连贯性断层扫描 (OCT) 和组织病理学用于ISR评估.
主要方法:
- 十二只迷你猪用开环或闭环装置进行了耳支架.
- 这些动物接受了抗血小板治疗.
- 90天后的评估包括数字减去血管学 (DSA),OCT,组织病理学和电子显微镜.
主要成果:
- 这两种支架类型都表现出ISR,通过海外国家和地区观察到的可比的新极端扩散.
- 在支架类型之间没有发现ISR发生率或尺寸的显著差异 (p=0.110).
- OCT和血素-素染色显示在评估新理想面积方面具有很高的一致性.
结论:
- 成功建立了一种用于动脉ISR的新型猪模型.
- 在这个模型中,开环和闭环支架表现出类似的ISR结果.
- OCT是评估支架状况的可靠工具,与组织病理学可比,尽管需要使用更大的样本大小进行进一步验证.

The Brachial Artery: Primary Site for Blood Pressure Measurement
Equipments Used To Measure Blood Pressure
This invasive approach involves cannulating a peripheral artery. During each cardiac contraction, pressure generates mechanical motion within the catheter, transmitted through rigid, fluid-filled tubing to a transducer. This transducer converts mechanical motion into electrical signals displayed as waveforms on a monitor. An automatic flushing system prevents blood backflow. Due to the potential risk of unexpected arterial blood loss, this method is primarily used in intensive...
