概括
程序内束CT (CBCT) 动脉图改善支气管动脉栓塞 (BAE) 通过更好地识别罪祸首动脉. 这导致更多的血管栓塞,减少复发性血栓塞,并且在没有增加风险的情况下重复手术的次数更少.
科学领域:
- 干预性放射学 干预性放射学
- 血管成像 血管成像
- 肺部医学 肺部医学
背景情况:
- 支气管动脉栓塞 (BAE) 是血栓塞的主要治疗方法.
- 准确识别罪祸首动脉对于成功的BAE至关重要.
- 术前CT血管造影 (CTA) 可能并不总是识别所有相关动脉.
研究的目的:
- 评估过程内形光束CT (CBCT) 动脉图对BAE期间罪祸首动脉识别的影响.
- 评估CBCT指导的BAE对临床结果的影响.
主要方法:
- 282名患者 (317个BAE程序) 的回顾性审查.
- 组A:只有程序前的CTA (n=177).
- 组B:程序前CTA加上程序内CBCT的动脉图 (n=105).
- 在不同组之间对罪祸首动脉检测,栓塞血管数,手术时间和临床结果进行比较.
主要成果:
- 与CTA相比,CBCT动脉图识别了更多的非支气管系统动脉 (16对3).
- 乙组的血管栓塞平均数量较高 (2.47对2.03) 和手术时间较短 (37.4对43.6分钟).
- 在B组,复发性血的发生率较低 (8.7%与17.5%相比),需要进行后续手术的次数较少 (4.8%与12.4%相比).
- 两组之间功能或辐射剂量 (DAP) 没有显著差异.
结论:
- 程序内CBCT动脉图增强了BAE中的罪祸首动脉栓塞.
- 这种技术通过减少血栓塞的复发和重新干预的需要来改善临床结果.
- 与基于CTA的标准程序相比,CBCT引导的BAE是安全的,没有增加脏或辐射风险.

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...

Radiological Investigation III: Pulmonary Angiogram and PET Scan

Radiological investigations are paramount in the diagnosis and management of various pulmonary diseases. Two essential investigations are the Pulmonary Angiogram and the Positron Emission Tomography (PET) Scan.
Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...
