概括
脊髓脑脊液 (CSF) 泄漏可能导致模仿前性痴呆症的症状. 通过MRI静脉图识别的阿齐戈斯静脉狭窄,可能导致脑综合征,在一些患者中是可治疗的原因.
科学领域:
- 神经学 神经学
- 神经外科 神经外科
- 放射学 放射学是一门学科.
背景情况:
- 行为变异性前性痴呆症 (bvFTD) 症状可能来自自发的内低血压和严重的脑.
- 识别脊髓大脑脊髓液 (CSF) 泄漏是具有挑战性的,标准治疗的成功也有限.
- 系统静脉循环异常与CSF泄漏病理学有关.
研究的目的:
- 在患有bvFTD垂脑综合征和反复性症状的患者中调查全身静脉循环.
- 为了确定脑脊液 (CSF) 损失导致大脑松的潜在静脉原因.
主要方法:
- 对21名患有bvFTD松大脑综合征但没有可识别的脊髓中枢液泄漏的患者的回顾性审查.
- 进行了全身静脉循环成像 (MR或CT静脉图).
- 患者报告的结果使用SIH残疾评估得分 (SIHDAS) 进行评估.
主要成果:
- 七名患者 (33%) 呈现静脉狭窄.
- 在3名患者中发现了阿齐戈斯静脉狭窄症,2名患者在支架放置后表现出显著的症状改善.
- 其他静脉 (关静脉,静脉) 或脊髓静脉通路的狭窄并没有产生临床改善.
结论:
- 孤立的阿齐戈斯静脉狭窄是导致脊髓中枢液损失和脑综合征的潜在原因.
- 系统性静脉成像,特别是形系统,应考虑耐火性bvFTD松大脑综合征.

01:19Veins of Head and Neck
1.3K
The blood drainage from the head and neck is primarily managed by three pairs of veins: the external jugular, internal jugular, and vertebral veins. The external jugular veins drain superficial scalp and face structures, passing over the sternocleidomastoid muscles to empty into the subclavian veins.
On the other hand, the vertebral veins, unlike their arterial counterparts, are not primarily responsible for brain drainage. Instead, they drain the cervical vertebrae, spinal cord, and some small...

Prosopagnosia, also known as face blindness, is the inability to recognize faces. In severe cases, individuals with prosopagnosia may not recognize close family members, including parents and spouses, by their faces. For instance, someone with prosopagnosia might walk past their child in a crowd, only realizing their mistake upon noticing their child's distinctive backpack or favorite jacket. Prosopagnosia specifically impairs facial recognition, while the recognition of other objects or...

01:26Alzheimer's Disease: Overview
439
Alzheimer's Disease (AD) is a continually advancing neurodegenerative disorder, distinguished by escalating memory loss, cognitive dysfunction, and dementia. The disease unfolds in three stages: preclinical, mild cognitive impairment (MCI), and dementia. Its onset is insidious, and the progression gradual, with the cause not well explained by other disorders.
The clinical diagnosis of AD hinges on the presence of memory and other cognitive impairments. Biomarkers, such as changes in Aβ...

01:19Veins of Thorax

The azygos system is a crucial part of the body's circulatory system and drains most of the thorax. It comprises the azygos, hemiazygos, and accessory hemiazygos veins.
The azygos vein, positioned just right of the midline and anterior to the vertebral column, begins at the junction of the right ascending lumbar and subcostal veins, terminating in the superior vena cava. This vein drains blood from the right side of the thoracic wall, thoracic viscera, and posterior abdominal wall.

497
Glaucoma is an eye condition characterized by increased intraocular pressure that damages the retina and optic nerve, leading to irreversible blindness if left untreated. The human eye has various components, including the cornea, iris, pupil, lens, and optic nerve. Aqueous humor is secreted by the epithelium of the ciliary body in the posterior chamber and flows through the trabecular meshwork and canal of Schlemm, maintaining normal intraocular pressure. The trabecular meshwork and the canal...

01:16Vascular Spasm
1.2K
The vascular phase, also known as vasospasm, is the initial stage of hemostasis, crucial for preventing excessive bleeding when a blood vessel is injured. After a vessel is cut, nerves in the damaged area trigger pain and other sensory impulses. Simultaneously, the smooth muscles in the vessel wall contract, resulting in a vascular spasm. This contraction reduces the vessel's diameter at the injury site, slowing or stopping blood loss through the vessel wall. Vascular spasms typically last...
