概括
标准成像可能低估了跨动脉再血管化 (TCAR) 资格. 中线CTA和双US提供了更准确的测量,特别是在曲性动脉,改善了患者对TCAR的选择.
科学领域:
- 血管外科 血管外科
- 医疗成像医学成像
- 干预心脏病学 干预心脏病学
背景情况:
- 穿动脉再血管化 (TCAR) 是一种有效的动脉支架方法.
- 对TCAR的解剖学资格往往受关节到状腺分叉长度 (<5厘米) 的限制.
- 传统的直线计算机断层血管造影 (CTA) 可能低估了这一关键距离.
研究的目的:
- 为了比较使用直线CTA,中线CTA和手术内双声超声 (美国) 的关节骨到状腺分叉长度测量.
- 评估常见动脉 (CCA) 扭曲度对测量差异的影响.
- 确定最佳的成像模式来评估TCAR解剖学资格.
主要方法:
- 70个跨动脉再血管化 (TCAR) 程序 (2016-2019) 的回顾性审查.
- 用直线CTA,中线CTA和手术内双重US与部延伸/旋转来测量的关节骨到状腺分叉长度的比较.
- 对患者和成像特征的分析,重点关注CCA扭曲度,与测量差异 (≥0.5厘米) 相比.
主要成果:
- 中线CTA (7.2厘米) 和双重US (7.0厘米) 的测量比直线CTA (6.4厘米) 长得多.
- 测量差异≥0.5厘米与曲的CCA有关 (60.0%对美国的19.1%; 51.4%对中心线CTA的0.0%).
- 在曲的CCA中,双重US和中线CTA相比直线CTA增加了1.0-1.1厘米,US和中线CTA之间有很强的相关性.
结论:
- 直线CTA低估了穿关节至心脏动脉分叉长度的跨心脏动脉再血管化 (TCAR) 候选人,特别是那些有曲的CCA的候选人.
- 双US与外科定位和中线CTA提供更准确和更长的测量.
- 这些先进的成像方法被推用于评估TCAR在患者的解剖资格扭曲的动脉血管.

Cardiac computed tomography (CT) scanning is an advanced cardiac imaging technique that utilizes CT technology, with or without intravenous (IV) contrast, to produce accurate cross-sectional virtual slices of specific areas of the heart, coronary circulation, and major blood vessels such as the aorta, pulmonary veins, and arteries. The computer processes these slices to generate three-dimensional images. Multidetector CT (MDCT) is a rapid form of CT scanning that captures multiple slices...

Cardiovascular magnetic resonance imaging, or CMRI, is a non-invasive diagnostic test that employs a magnetic field and radiofrequency waves to create precise images of the heart and arteries. It provides comprehensive information about cardiac anatomy, function, perfusion, and tissue characterization without ionizing radiation.IndicationsCMRI diagnoses various heart conditions, including tissue damage from heart attacks, ischemic heart disease, myocarditis, aortic issues (tears, aneurysms,...
