Aneurysm III: Interprofessional Care

478
Aneurysm management involves either conservative medical therapy or surgical intervention, depending on the size and symptoms of the aneurysm. Conservative management is generally reserved for smaller, asymptomatic aneurysms, while larger or symptomatic aneurysms often necessitate surgical repair.Conservative Medical TherapyFor small, asymptomatic aneurysms, particularly abdominal aortic aneurysms (AAA) less than 5.5 centimeters in diameter, conservative medical therapy is recommended. This...

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:

  • 血管外科 血管外科
  • 医疗成像医学成像
  • 医疗信息学 医疗信息学

背景情况:

  • 目前对内血管大动脉修复 (EVAR) 和窗户式EVAR (FEVAR) 的监测缺乏个性化.
  • 治疗策略是个性化的,但后续成像通常使用一种适合所有人的方法.

研究的目的:

  • 提出和评估一个模块化成像算法,用于EVAR和FEVAR之后的个性化监控.
  • 根据侵袭性和临床需要,升级成像强度.

主要方法:

  • 对EVAR和FEVAR患者的单中心队列的回顾性分析.
  • 实现一个模块化成像算法,从B模式超声波开始,到Duplex超声波,B-Flow和对比增强超声波 (CEUS).
  • 在必要时使用CT血管造影 (CTA);对内泄漏检测率的比较分析.

主要成果:

  • 这项研究包括28名EVAR和40名FEVAR患者,包括101次随访和431次成像研究.
  • 与对比度增强的超声波 (CEUS) 显示出最高的内泄漏检测率,其次是CTA和B-Flow.
  • 双重超声波和B-Flow显示低假阳性率 (分别为0和1);CEUS是参考标准.
  • 在6名患者中,在Duplex或B-Flow通过Duplex或B-Flow检测出阳性内漏洞后,CEUS被遗漏,导致治疗成功,没有不良事件.

结论:

  • 模块化成像算法支持个性化医疗在EVAR/FEVAR后的监测.
  • 像Duplex超声波和B-Flow这样的不那么侵入性和资源密集型成像可能会在阳性时取代先进的方法 (CEUS,CTA) 来检测内泄漏.
  • 这种方法可以优化资源利用和患者管理.
