Imaging Studies for Cardiovascular System VI: Calcium -Scoring CT

116
Calcium-Scoring CT ScanA calcium-scoring CT scan, also known as coronary artery calcium (CAC) scan, detects calcium deposits in the coronary arteries. This test assesses the risk of coronary artery disease (CAD), which can lead to cardiovascular events such as angina, heart failure, and sudden cardiac arrest.A calcium-scoring CT scan is generally recommended for individuals at intermediate risk of CAD without symptoms. It includes:Men aged 40-75 and women aged 50-75: Especially those with a...

Venous Thrombosis II: Clinical Manifestations and Diagnostic Studies

33
The key difference between Superficial Vein Thrombosis (SVT) and Deep Vein Thrombosis (DVT) lies in their location and severity.Clinical ManifestationsSVT typically presents with localized pain, tenderness, and redness along the course of a superficial vein, often accompanied by a palpable, cord-like structure under the skin. This condition is usually less dangerous than DVT but can be uncomfortable and may lead to complications such as cellulitis or, rarely, a clot extension into the deep...

概括

新的CTA附带损伤评分 (CCIS) 结合动脉和静脉评估可以准确预测中风的结果. 在急性缺血性中风患者中,较高的CCIS得分与较差的功能结果和较高的死亡率相关.

科学领域:

  • 神经学
  • 放射学
  • 心血管研究

背景情况:

  • 对于急性缺血性中风的结果来说,附带循环非常重要.
  • 对CTA的动脉和静脉附带评估具有预后价值,但通常被单独分析.
  • 之前的方法缺乏统一的方法来评估结合的动脉和静脉附带状态.

研究的目的:

  • 开发和验证CTA附带损伤评分 (CCIS),这是动脉和静脉附带损伤的综合测量.
  • 研究CCIS与前部循环大血管封闭 (LVO) 中90天功能结果之间的关联.
  • 与现有的中风成像得分相比,评估CCIS的预测性能.

主要方法:

  • 在1080名前部循环LVO中风患者进行的回顾性队列研究.
  • 通过结合 (动脉) 和皮层静脉化评分 (COVES) (静脉) 评分来开发CCIS.
  • 分析CCIS与修改的兰金尺度 (mRS) 评分和90天死亡率的相关性.

主要成果:

  • 随着CCIS的增加,有利的结果 (mRS 0-2) 显著下降 (CCIS 0 的66%,CCIS 1 的32%,CCIS 2 的17%).
  • 在CCIS较高的情况下,死亡率增加 (11%在CCIS0,25%在CCIS1,36%在CCIS2).
  • CCIS对于有利的结果和死亡率都表现出强大的独立预测价值,表现优于ASPECTS.

结论:

  • CCIS是一种强大的复合成像生物标志物,用于预测急性缺血性中风的90天结果.
  • 将CCIS整合到急性中风成像中可以提高风险分层,并为治疗决策提供信息.
  • 这种新的评分提供了比单个动脉或静脉评估更全面的担保状态.
