概括
内动脉 (ICA) 异常,如扭曲和扭曲,在四周以下的小马中很常见. 这些动脉多利科动脉病变似乎是短暂的解剖变异,而不是病理状况,在成年马中不存在.
科学领域:
- 兽医解剖学 兽医解剖学
- 马类医学 马类医学
- 血管形态学 血管形态学
背景情况:
- 不典型的内动脉 (ICA) 课程偶尔在喉囊内镜检查期间观察到小马,与成年马不同.
- 有限的兽医数据存在于哺乳动物动脉异常,与广泛的人类研究对ICA dolichoarteriopathies (扭曲,扭曲或卷曲的血管) 相反.
研究的目的:
- 要确定小的ICA异常是否符合 dolichoarteriopathies 的定义.
- 与成年人相比,评估新生儿小羊中这些动脉异常的发生率.
主要方法:
- 对50头小 (<4周大) 的口袋进行内镜检查,以可视化额外头骨ICA.
- 解剖学研究使用从20匹马头 (小羊和成年人) 获得的额外头骨ICAs的血管件.
主要成果:
- ICA异常 (扭曲,扭曲,卷曲) 仅在小于4周的小马身上发现,在成年人身上没有.
- 幼中多利霍动脉病的高发病率:66% (内镜) 和71% (解剖学研究),主要是双边的.
- 形是最常见的异常,没有观察到性别偏好.
结论:
- 子ICA异常,以扭曲,扭曲和卷曲为特征,代表了多利霍动脉病变.
- 这些血管变异可能是由于过度的ICA长度而导致的短暂解剖变异,而不是病理状况.
- 研究结果表明,这些异常随着年龄的增长而消失,并不会对马的健康造成损害.

3.3K
The subclavian artery transitions into the axillary artery as it exits the chest and enters the axillary region. This artery is critical for supplying blood to the shoulder area, including the head of the humerus, through the humeral circumflex arteries. As the vessel continues into the upper arm or brachium, it becomes the brachial artery. This artery plays a key role in vascularizing the brachial region and bifurcates at the elbow into several branches. These branches include the deep...

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...
