Imaging Studies VII: Vascular Imaging

DefinitionRenal angiography, also known as renal arteriography, is an imaging technique used to obtain a comprehensive view of blood flow and the vascular structure of blood vessels in the kidneys and surrounding areas.PurposeRenal angiography detects blood vessel abnormalities in the kidneys, such as aneurysms, stenosis, thrombosis, vascular tumors, and renal artery stenosis. It evaluates kidney function and guides interventional treatments like angioplasty or stent placement.Pre-Procedure...

科学领域:

  • 心脏电生理学 心脏电生理学
  • 干预心脏病学 干预心脏病学
  • 医疗成像医学成像

背景情况:

  • 室内动脉冲动 (VT) 移除对于心肌梗塞 (MI) 后患者的节律控制至关重要.
  • 目前的静脉瘤切除工作流程是可变的,并且取决于医生,这突显了对标准化方法的需求.

研究的目的:

  • 通过心脏计算机断层扫描 (CT) 来评估静脉管切除的初始系统经验,以准壁厚异质性.
  • 评估CT识别的通道作为在MI后VT切除中绘制的静脉脉峡的替代品.

主要方法:

  • 包括连续患有后MI VT的患者,他们进行了第一次静脉除 (2017年1月至2022年5月).
  • 根据CT扫描的壁厚异质性,确定了基于CT扫描的切除目标.
  • 执行CT指导的射频除,旨在阻止或使CT通道无法捕获,随后进行诱导性测试,并在必要时进行补充映射/除.

主要成果:

  • 包括39名患者 (97.4%男性,LVEF35±10%);平均每位患者发现3.6个CT通道.
  • 最初的CT导向切除在48.7%的患者中实现了非诱导性;48.7%仍然是可诱导的,其中大多数来自边境地区.
  • 在补充切除后,7.7%的患者仍然可以诱导. 长期无静脉瘤生存率为61.9%,平均随访时间为47.8个月.

结论:

  • 针对壁厚异质性的CT导向静脉除是缺血性心肌病患者的可行和安全的策略.
  • 这种以成像为指导的方法为静脉瘤切除提供了一种系统的方法,有可能改善节律控制结果.
