概括

一个高的PET血管活动评分 (PETVAS) 预测了Takayasu的血管进展.

科学领域:

血管炎症是一种血管炎症.
核医学成像技术核医学成像技术
类风湿病学类风湿病学

背景情况:

动脉壁的氧葡萄糖 (FDG) 吸收表明,在塔卡亚苏动脉炎 (TAK) 中血管炎症.
在TAK中,FDG吸收对血管预后的预测价值尚未得到充分确立.

研究的目的:

评估PET血管活动评分 (PETVAS) 作为TAK中的血管预后的预测指标.
确定特定动脉区域的FDG吸收是否与TAK中的血管学进展相关.

主要方法:

一项前性观察队列研究包括了接受基线18F-FDG PET/CT和血清学测试的TAK患者.
血管成像 (MRA/CEUS) 在基线和每六个月进行一次.
计算了PETVAS,血管图的进展被定义为新的或恶化的病变.

主要成果:

基线PETVAS与炎症标志物 (ESR,IL-6,血小板) 有积极的相关性.
血管学进展发生在36.6%的患者中,平均随访时间为30个月.
基线PETVAS>15是血管学进展的独立预测因子 (HR1.93,p=0.04).

结论:

基线PETVAS>15独立地预测了Takayasu动脉炎的血管学进展.
在特定的动脉区域吸收FDG与血管进展无关.
PETVAS提供一种可行的基于PET/CT的标记物,用于预测TAK的血管进展,强调需要定期进行成像监测.

Peripheral Arterial Disease II: Clinical Manifestations and Diagnostic Evaluation

Clinical manifestationsPeripheral Arterial Disease (PAD) manifests through a range of symptoms, from the characteristic intermittent claudication to atypical presentations and severe complications in advanced stages. Intermittent claudication, a hallmark symptom of PAD, presents as exercise-induced muscle pain that typically resolves within minutes of rest. This pain is reproducible and stems from inadequate blood flow, leading to the accumulation of lactic acid produced during anaerobic...
