概括
非酒精性脂肪肝疾病 (NAFLD) 改变了门静脉的血液流动,在所有肝脏部分的速度降低. 流量重新分配有利于左叶是显而易见的,特别是在NAFLD患者与门门高血压.
科学领域:
- 肝病学 肝病学是一种肝病学.
- 放射学 放射学是一门学科.
- 血管医学 血管医学
背景情况:
- 非酒精性脂肪性肝病 (NAFLD) 是一系列的肝病.
- 先进的NAFLD可以发展为非酒精性脂肪肝炎 (NASH) 和门性高血压.
- 评估门静脉流动力学对于理解NAFLD进展至关重要.
研究的目的:
- 为了评估NAFLD患者门静脉流速的细分变化.
- 为了比较健康对照组之间的流速,NAFLD患者没有门高血压,NASH患者有门高血压.
- 为了识别潜在的多普勒超声波标记物,用于NAFLD相关的循环变化.
主要方法:
- 展望性,观察性,病例控制研究设计.
- 彩色多普勒超声波测量所有八个肝脏部分的门静脉最大速度.
- 在三个组中比较速度:健康对照组 (n=30),无门高血压的NAFLD (n=32) 和带有门高血压的NASH (n=13).
主要成果:
- 与对照组相比,NAFLD患者在所有肝脏部分的门静脉速度显著降低.
- 在第2段与第7段的门静脉峰值速度的比率在NAFLD患者 (1.03±0.21) 和对照组 (0.90±0.17) 中显著更高.
- 这一比率在NASH门户高血压组 (1.83±0.40) 中甚至更高,p=0.003.
结论:
- NAFLD导致门静脉流再分配,增加流向左叶的流量.
- 这种流量再分配在患有门高血压的NAFLD患者中更为明显.
- 多普勒超声波可以检测到NAFLD中的这些循环改变,可能有助于评估疾病严重程度和并发症.

Peripheral Arterial Disease II: Clinical Manifestations and Diagnostic Evaluation
14
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...
