概括
窗口内血管大动脉修复 (FEVAR) 期间的导管时间在向下定向的目标血管 (TVs) 和骨狭窄时较长. 这些在CT扫描中识别的解剖特征预测了FEVAR的更长的程序时间.
科学领域:
- 血管外科 血管外科
- 干预性放射学 干预性放射学
- 医疗成像医学成像
背景情况:
- 在窗口内血管大动脉修复 (FEVAR) 中对目标血管 (TV) 进行导管,是复杂的,增加了辐射暴露和手术持续时间.
- 电视的解剖学变化可以显著影响程序效率和安全.
研究的目的:
- 确定计算机断层扫描 (CT) 扫描中的目标血管 (TV) 的解剖特征与FEVAR期间的导管时间之间的相关性.
- 在FEVAR手术中确定长时间导管治疗的预测性解剖标记.
主要方法:
- 一项前性单中心研究分析了40名在2020年5月至2022年4月期间接受FEVAR (不包括特定类型) 的患者.
- CT扫描测量包括电视直径,大动脉直径,角度和骨狭窄 (>50%). 记录了从导线插入到支架放置的导管时间.
- 单变量和多变量分析将解剖学参数与导管时间相关联.
主要成果:
- 分析了132台电视机;脏动脉 (7分钟),上层介质动脉 (4.5分钟) 和腹腔干 (CT) (13分钟) 显示出不同的导管时间.
- 在16%的电视机中存在骨狭窄.
- 在单变量和多变量分析 (P=0.01和P<0.0001分别) 中,TV角度 (向下方向) 和骨狭窄是延长导管时间的显著预测因素.
结论:
- 目标血管的向下角和骨狭窄独立地与FEVAR的导管时间增加相关.
- 这些发现建议考虑替代方法,如手臂接入或可转向的外,以应对具有挑战性的电视解剖.
- 使用CT成像的程序前规划可以帮助预测和减轻FEVAR期间潜在的延迟.

198
Nursing responsibilities before cardiac catheterization include:Assess for allergies and establish baseline health status.Before cardiac catheterization, assess the patient for allergies to contrast dye. Perform a comprehensive baseline assessment, including vital signs, heart and breath sounds, and a neurovascular assessment of the extremities, noting distal pulses, skin color, and temperature. Instruct the patient to fast for 8-12 hours before the procedure. Evaluate baseline laboratory...

Cardiac catheterization is an invasive diagnostic technique used to identify and evaluate structural and functional diseases of the heart and major blood vessels. This technique diagnoses congenital heart disease, coronary artery disease, valvular heart disease, and coronary spasms and assesses ventricular function. It helps guide treatment decisions, including the need for revascularization procedures like percutaneous coronary intervention (PCI) or coronary artery bypass grafting (CABG) and...
