- 血管神经学 血管神经学
背景情况:
- 大脑角 (CPA) 包含关键的神经血管结构,包括神经和前下大脑动脉 (AICA).
- 在CPA中,血管压缩与神经疼痛有关,但其在耳和头等耳症状中的作用尚不清楚.
研究的目的:
- 用MRI在没有音声静脉症状的患者中研究CPA水箱中AICA血管环的患病率.
- 评估AICA循环与听力损失,耳或头的发生之间的关系.
主要方法:
- 对114个成年人MRI研究的回顾性分析,使用高分辨率的3D-CISS序列.
- 由两名放射科医生进行独立审查,以使用Chavda的分类来识别和分类CPA和内部声学介质中的AICA血管环.
- 排除具有相关病史或图像质量差的患者.
主要成果:
- 在无症状个体中观察到AICA血管环的显著流行率 (47.6%).

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.

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...
