概括
多谱光声学断层扫描 (MSOT) 显示出评估下肢再血管化 (LER) 结果的前景. 在LER后增加的氧化血红蛋白与更好的结果相关,这表明MSOT.
科学领域:
- 血管外科 血管外科
- 医疗成像医学成像
- 血液动力学 血液动力学
背景情况:
- 下肢再血管化 (LER) 的目的是恢复血液流动.
- 评估LER后的治疗有效性和组织输液是至关重要的.
- 目前的方法在实时输液评估方面可能存在局限性.
研究的目的:
- 评估多谱光声学断层扫描 (MSOT) 的可行性,用于监测含氧血红蛋白 (HbO2) 变化.
- 在LER之前和之后评估下肢肌肉中的HbO2水平.
- 为了将MSOT发现与临床结果和复原率相关联.
主要方法:

Peripheral Arterial Disease II: Clinical Manifestations and Diagnostic Evaluation
35
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...
