- 移植医学 移植医学
- 医疗成像医学成像
背景情况:
- 评估主要四肢动脉的基础血 perfusion 对于优化四肢移植期间的ex vivo perfusion 保存至关重要.
- 建立规范性血液动力学参数对于指导移植程序中的流量选择至关重要.
研究的目的:
- 为了研究主要上肢和下肢动脉的基础血 perfusion.
- 分析身体质量指数 (BMI),身体表面积 (BSA) 和动脉血液输液体积之间的关系.
- 为了指导肢体再移植中的ex vivo perfusion 保存的流速选择.
主要方法:
- 招募了304名志愿者 (18-65岁) 进行体检.
- 使用便携式多普勒超声系统测量了血管直径,血液流速和血液 perfusion 容量在臂部,部,放射性,部,背部脚部和后部动脉.
- 采用多重线性回归和相互作用测试来分析BMI,BSA和四肢血流之间的相关性,考虑性别和"三高"状态.
主要成果:
- 对上肢 (手臂,肘部,半径) 和下肢 (骨,背部脚部,部后部) 动脉建立了平均输血量.
- 多重线性回归显示,BMI与动脉血 perfusion 量之间存在负相关性,与BSA之间存在正相关性.
- 观察到BMI和BSA之间对四肢血流的统计学显著的相互作用效应 (p < 0.05).
结论:
- 量化超声波衍生的肢体 perfusion 参数及其与 BMI/BSA 的相关性,使机器 perfusion 系统在肢体移植中能够进行血液动力学定制.
- 这种方法平衡了代谢支持,并在体外保存期间减轻了缺血-再输血风险.

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...

Blood pressure measurement is a fundamental clinical procedure, providing crucial data for assessing cardiovascular health. Among the various sites for this measurement, the brachial and popliteal arteries are predominantly utilized due to their accessibility and the reliability of their readings. This lesson delves into the anatomical significance, methodology, and considerations of measuring blood pressure at these locations.
