概括
与对照组相比,异常性内高血压 (IIH) 患者因arachnoid颗粒 (AGs) 的静脉鼻缩小的持续时间较小. 较小的AG可以通过减少脑脊液再吸收来促进IIH.
科学领域:
- 神经成像是一种神经成像.
- 神经外科 神经外科
- 神经学 神经学
背景情况:
- 异常性内高血压 (IIH) 涉及内压力升高,导致头痛和视力丧失.
- 大脑静脉排水阻塞是IIH病变的可疑因素.
- 甲状腺颗粒 (AGs) 可以影响静脉鼻口径.
研究的目的:
- 为了比较 IIH 患者与健康对照患者的 AG 持续静脉鼻收窄的程度.
- 调查AG大小,鼻腔尺寸和IIH之间的关系.
- 探索静脉鼻解剖在IIH发展中的作用.
主要方法:
- 对43名IIH患者和43名对照进行了回顾性病例控制研究.
- 对3D对比增强型MRI扫描进行分析.
- 测量AG数,AG部位和标准点的鼻腔直径,以及最小横侧/半侧鼻腔宽度.
主要成果:
- 在IIH患者中,相对鼻狭窄的AGs较少 (对照组7%vs11%;p=0.009).
- 在IIH患者中,鼻直径在AG位点较标准点大 (70mm2比48mm2;p=0.010).
- 在IIH患者中,上斜鼻 (SSS) 的AG较小 (3mm2对5mm2;p=0.023) 和细分较宽 (69mm2对52mm2;p=0.002),而右横鼻则较窄 (p<0.001).
结论:
- 与假设相反,IIH患者通过AGs显示较少的鼻狭窄,特别是在SSS.
- 在IIH患者中较小的AG可能会降低脑脊液的吸收,促进IIH.
- 另一方面,IIH中较窄的横向/双面鼻可能会导致SSS的逆压,扩大SSS并压缩AGs.

01:25Glaucoma: Overview
538
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...

01:27Open Angle Glaucoma: Treatment
427
In open-angle glaucoma, the iridocorneal angle remains open, but the trabecular meshwork becomes stiff, slowing down the outflow of aqueous humor. This causes a buildup of aqueous humor in the anterior chamber, leading to a sudden increase in intraocular pressure. The treatment for open-angle glaucoma focuses on reducing the elevated intraocular pressure by either decreasing the secretion of aqueous humor or increasing its outflow.

01:28Angle Closure Glaucoma: Treatment
471
Angle-closure glaucoma, or closed-angle glaucoma, is an eye condition where the iris bulges out and blocks the iridocorneal angle, resulting in a buildup of aqueous humor and increased intraocular pressure. Immediate medical attention is necessary due to the sudden onset of symptoms. The treatment for angle-closure glaucoma includes short-term and long-term approaches. Short-term treatment involves using eye drops like pilocarpine to lower intraocular pressure by increasing aqueous humor...

01:19Cranial and Spinal Meninges
1.4K
The cranial and spinal meninges are complex protective structures surrounding the central nervous system (CNS), consisting of the brain and spinal cord. These meninges consist of the dura mater, the arachnoid mater, and the pia mater. They protect the CNS, provide structural support, and aid in circulating cerebrospinal fluid (CSF).
Cranial Meninges
These meningeal layers cover the cranium. The dura mater is the outermost layer of cranial meninges. It is a thick and durable membrane of dense...

01:19Veins of Head and Neck
1.7K
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...
