概括

晚期斑块突出 (PP) 后动脉支架 (CAS) 可能发生在手术后两周. 病理学检查证实PP是双层微型网状支架放置后迟填充缺陷的原因.

科学领域:

干预神经病学干预神经病学
血管外科血管外科
心脏病学心脏病学

背景情况:

动脉支架 (CAS) 是治疗内动脉狭窄的一种常见手术.
在CAS程序中越来越多地使用双层微混凝土支架.
在CAS后的晚期并发症需要彻底调查.

研究的目的:

在CAS之后报告一个罕见的迟填充缺陷的案例.
通过病理学检查来调查迟填充缺陷的原因.

主要方法:

冠状动脉支架 (CAS) 是在一个83岁的妇女身上进行的,她患有严重的左侧内侧冠状动脉狭窄.
在CAS后进行了连续的动脉超声波.
为了解决填充缺陷,采用了支架内支架技术.
收集碎片并进行病理检查.

主要成果:

1周内初始超声波显示没有斑块突起 (PP).
在术后第17天发现了显著的填充缺陷.
检索到的残骸的病理检查表明PP延迟.

结论:

这是第一份报告,表明延迟PP是双层微混凝土支架后CAS后延迟填充缺陷的原因.
斑块突出可能发生在CAS后两周以上.

Atherosclerosis I: Introduction

Atherosclerosis I: Introduction

Atherosclerosis is a progressive disorder characterized by the buildup of plaques on the arterial inner wall, causing them to narrow and harden over time. These plaques comprise lipids, calcium, blood components, carbohydrates, and fibrous tissue. The process primarily affects the intima of large and medium-sized arteries, reducing blood flow in any artery.Etiology and risk factorsThe cause of atherosclerosis is multifactorial, involving a complex interplay among endothelial injury, lipid...
