概括

了解非静脉性膝下动脉动脉样硬化是改善内血管治疗 (EVT) 结果的关键. 这一案例系列使用光频域成像 (OFDI) 和血管镜来探索EVT患者的BTK动脉特征.

科学领域:

血管外科血管外科
干预心脏病学干预心脏病学
医疗成像医学成像

背景情况:

内血管治疗 (EVT) 是慢性肢体威胁性缺血的标准,向膝下动脉 (BTK).
高的再干预率需要更深入地了解BTK动脉动脉样硬化.
这项研究调查了EVT患者的非静脉性BTK动脉动脉样硬化.

研究的目的:

为了阐明非静脉性BTK动脉动脉样硬化的特征.
为了确定导致BTK动脉堵塞的因素,在EVT患者中.
探索BTK动脉封闭的潜在非动脉硬化机制.

主要方法:

五名患者的病例系列接受了表面大腿动脉 (SFA) 的EVT.
光频域成像 (OFDI) 和血管镜用于检查侧BTK动脉.
评估动脉样硬化的严重程度和危险因素.

主要成果:

两名患者表现出晚期动脉样硬化,而三名患者在检查的BTK动脉中表现出轻度动脉样硬化.
所有患者都有多重动脉样硬化风险因素和SFA/BTK动脉狭窄或闭塞.
一些BTK动脉狭窄/闭塞的患者缺乏显著的动脉样硬化,这表明了其他闭塞机制.

结论:

在接受EVT的患者中,BTK动脉动脉样硬化特征因患者而异.
系统性动脉样硬化的存在并不总是与BTK动脉疾病的严重程度相关.
需要进一步的研究来了解BTK动脉封闭的非动脉样硬化机制.

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...

Imaging Studies VII: Vascular Imaging

DefinitionRenal angiography, also known as renal arteriography, is an imaging technique used to obtain a comprehensive view of blood flow and the vascular structure of blood vessels in the kidneys and surrounding areas.PurposeRenal angiography detects blood vessel abnormalities in the kidneys, such as aneurysms, stenosis, thrombosis, vascular tumors, and renal artery stenosis. It evaluates kidney function and guides interventional treatments like angioplasty or stent placement.Pre-Procedure...
