概括
使用血管造影和计算机断层扫描血管造影 (CTA) 的术前成像是下肢自由重建的常见方法. 这两种方法都显示出低的并发症率,有助于复杂病例的手术规划.
科学领域:
- 血管外科 血管外科
- 重建性手术是一种重建性手术.
- 医疗成像医学成像
背景情况:
- 成功的下肢自由组织转移依赖于足够的血管解剖学和 perfusion.
- 计算机断层扫描血管造影 (CTA) 和传统血管造影是关键的成像工具,提供详细的可视化和流量评估.
- 目前缺乏用于下肢自由重建的手术前成像的标准化算法.
研究的目的:
- 评估手术前成像方法 (CTA和血管造影) 的利用和结果,以进行下肢自由重建.
- 在这个患者群体中评估CTA和血管学相关的并发症率.
- 为指导术前成像决策提出一个机构算法.
主要方法:
- 在2002年至2020年间,对405名接受下肢自由重建的患者进行了回顾性审查,通过当前程序术语 (CPT) 代码识别.
- 分析电子医疗记录以了解患者的人口统计,治疗细节,成像特征和实验室值.
- 评估的结果包括成像发现,相关并发症 (例如,对比引起的病) 和手术结果.
主要成果:
- 59%的患者接受了手术前血管造影,10%的患者接受了心血管造影,10%的患者接受了心血管造影,7.2%的患者接受了两者;24%的患者没有手术前成像.
- 在接受手术前成像检查的患者中,有40%的患者表现出不到三血管流失.
- 对血管造影和CTA都观察到较低的并发症率,对于对比诱导性病 (CIN) 没有确定统计学上显著的风险因素.
结论:
- 血管造影和CTA是用于下肢自由重建的常用和安全的成像方法.
- 很大一部分患者 (40%) 呈现低于最佳的血管流失,这凸显了彻底的手术前评估的重要性.
- 一个机构算法建议对患有外周血管疾病,硬件或与创伤相关的远部缺陷的患者进行血管造影.

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...
