概括
这项案例研究突出了一个95岁的阿尔茨海默氏症 (AD) 和严重的右侧内动脉 (ICA) 扭曲和动脉样硬化患者. 这些发现表明血管问题与认知衰退之间存在潜在联系,需要进一步调查.
科学领域:
- 神经学 神经学
- 血管外科 血管外科
- 病理学 病理学 病理学
背景情况:
- 阿尔茨海默病 (AD) 是一种进展性神经退行性疾病.
- 内动脉 (ICA) 异常,如曲,可以影响大脑血液流动.
- 血管病理和认知衰退之间的关系是正在进行的研究领域.
研究的目的:
- 报告一个独特的严重右ICA扭曲和动脉样硬化的病例,该病例发生在一具有AD病史的尸体中.
- 探索血管不全对认知衰退的潜在贡献.
主要方法:
- 一个95岁的女性尸体的死后解剖,记录了阿尔茨海默病.
- 用数字标尺对右侧内动脉 (ICA) 进行形态评估,以进行曲.
- 测量ICA光线直径和壁厚,以评估动脉样硬化.
主要成果:
- 右 ICA 呈现出显著的前下侧曲 (45° 下侧偏差,60° 上侧重定向).
- ICA光度为4.2毫米,焦壁厚度为2.5毫米,表明晚期动脉样硬化超过了曼海姆共识值.
- 没有组织学证实斑块组成;阿尔茨海默病的诊断是基于先前的病史.
结论:

The human body's intricate network of arteries ensures that every organ system receives the necessary oxygen and nutrients for optimal function. The arterial network in the head and neck region is particularly complex, providing vital blood flow to the brain, eyes, and other critical structures. Prominent arteries in this region include the internal carotid arteries and the vertebral arteries.

The coronary arteries, originating from the ascending aorta, bifurcate from two sinuses located within the ascending aorta. Positioned just above the aortic semilunar valve, these sinuses house essential aortic baroreceptors and chemoreceptors, crucial for maintaining cardiac function. The left coronary artery and the right coronary artery branch off from the left posterior and anterior aortic sinuses, respectively.
