概括
脊椎动脉 (VA) 异常,特别是高入口变异,在美国可能比以前认为的更常见. 这项尸体研究强调了需要详细的解剖数据和血管程序的术前成像.
科学领域:
- 人体解剖学 解剖学 解剖学
- 血管外科 血管外科
- 放射学 放射学是一门学科.
背景情况:
- 脊椎动脉 (VA) 变异被认为是不常见的,但可能不够报告.
- 没有以前的尸体研究专门分析了美国人口中的VA段1 (V1) 变异.
- 这项研究通过检查美国尸体中的V1解剖学来解决这个差距.
研究的目的:
- 为了确定V1段VA变异在美国捐赠人群中的流行率.
- 为了定义正常的V1 VA解剖学.
- 为了确定与VA变化的人口统计学关联.
主要方法:
- 来自美国三个州的188名全身捐赠者的剖析.
- 根据起源,入口水平,直径和长度,将前前的VA分类为正常或变异.
- 使用T测试,Chi-Square和费舍尔精确测试进行统计分析.
主要成果:
- 在86.17%的捐赠者中发现了正常的V1解剖; 13.83%的捐赠者有异常 (例如,异常起源,高入口,双VA).
- 左侧VA (LVA) 的起点直径明显大于右侧VA (5.31毫米对比4.77毫米).
- 随着年龄的增长,VA扭曲性增加,女性在右侧的扭曲性更大.
结论:
- 美国V1段VA异常的患病率 (13.83%) 可能超过之前的报告,特别是高入口变异.
- VA变种可能会使血管程序复杂化,这强调了手术前成像的必要性.
- 这些发现支持了特定区域的解剖数据的必要性,并表明了潜在的与年龄相关的LVA重塑.

Arteries of the Head and Neck
2.9K
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 internal carotid arteries supply blood to the anterior portion of the cerebrum. They enter the...

Spinal Cord: Cross-sectional Anatomy
4.1K
The cross-sectional anatomy of the spinal cord offers a detailed view of its complex structure and function within the central nervous system. At the core of the spinal cord lies the gray matter, characterized by its butterfly or "H"-shaped appearance in cross-section. This central region is enveloped by white matter, with the overall structure divided into symmetrical halves by the dorsal median sulcus and the ventral median fissure.
