概括
非静脉性动脉斑块 (<50%静脉缩) 在源不明的栓塞性中风 (ESUS) 中起作用. 这些斑块,特别是那些具有高风险特征的斑块,在症状方面更常见,这表明它们在ESUS中的重要性.
科学领域:
- 神经学 神经学
- 血管医学 血管医学
- 心脏病学 心脏病学
背景情况:
- 源不明的栓塞性中风 (ESUS) 占缺血性中风的很大一部分.
- 在ESUS中,非阻塞性 (<50%狭窄) 动脉斑块在ESUS中的作用仍在调查中.
- 了解斑块特征对于确定中风病因和指导治疗至关重要.
研究的目的:
- 为了评估ESUS患者的非静脉性 (<50%) 宫冠状动脉斑块的意义.
- 为了比较症状 (两侧动脉) 和无症状 (对侧动脉) 动脉中 carotid 斑块的特征.
- 为了识别与ESUS相关的斑块特征.
主要方法:
- 对81名ESUS患者的回顾性分析.
- 检查带有<50%狭窄的带斑块,检查其厚度,不规则性,,化和低密度等特征.
- 在ipsilateral和contralateral carotid动脉之间的斑块特征的比较.
主要成果:
- 厚度≥3mm的斑块更常见于两侧侧动脉 (P < .05).
- 斑块,不规则性,非化斑块和低密度是明显更频繁的ipsilaterally (P < .05).
- 在54.3%的患者中,在ipsilateral侧发现了斑块,而在contralateral侧发现的是29.6% (P = .0024).
结论:
- 非静脉性动脉斑,特别是那些具有高风险特征的斑块,在ESUS患者的症状动脉中明显更为普遍.
- 这些发现凸显了非阻塞性动脉斑块在ESUS中的潜在作用.
- 对于ESUS的临床评估和治疗策略,应考虑这些非硬膜性斑块.

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...

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...
