概括

膝下重血管化改善了直接和间接重血管化的脚血管体中的血液流动. 与开放式手术相比,内血管手术在直接再血管化的区域显示出更大的改善.

科学领域:

血管外科血管外科
干预性放射学干预性放射学
足部医学足部医学

背景情况:

针对特定血管细胞的有针对性的再血管化改善了伤口愈合和四肢挽救.
有限的数据存在于重血管化的足部血管体输液的影响.

研究的目的:

为了评估下关节动脉复血管化后足部血管体输液的变化.
为了比较直接再血管化的 (DR) 与间接再血管化的 (IR) 血管体中的 perfusion 变化.

主要方法:

使用氨酸绿色光成像 (ICG-FI) 测量重血管化前后足部 perfusion 的前景研究.
血管系根据血管图分类为DR或IR.
红外血管组进一步分为IR_Coll+ (强有力的抵押品) 和IR_Coll- (弱/没有抵押品).

主要成果:

手术和内血管再血管化都显著增加了DR和IR血管体的输液.
绕道手术显示了DR和IR血管体的类似 perfusion 增加.
与IR血管相比,Endovascular revascularization在DR血管体中产生了显著更大的 perfusion 增加 (40U vs. 26U).
在内血管再血管化后,IR_Coll+血管体显示出显著的 perfusion 增加,与IR_Coll-血管体不同.

结论:

开放的再血管化在DR和IR血管体中同样改善了 perfusion.
内血管再血管化优先增加DR血管体的输液.
一个强大的附带网络对于增强间接再血管化的血管体 perfusion 是至关重要的.

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...
