概括

扩散性脑血管扩张发生在30%的可逆脑血管收缩综合征 (RCVS) 患者的疾病早期. 这一发现与出血风险增加有关,在女性和二次RCVS病例中更为常见.

科学领域:

神经学神经学
血管神经学血管神经学
神经成像是一种神经成像.

背景情况:

可逆脑血管收缩综合征 (RCVS) 通常表现为雷击头痛和动脉血管收缩.
以前的报道表明,早期RCVS可能涉及扩散的大脑血管扩张,挑战传统观点.
这项研究调查了RCVS早期扩散性脑血管扩张的发生和特征.

研究的目的:

报告在RCVS早期阶段扩散性脑血管扩张的发生率.
分析表现为扩散血管扩张的RCVS患者的临床和预后特征.
为了比较患有和没有早期扩散性脑血管扩张的患者.

主要方法:

对RCVS患者病历的回顾性分析.
初始和后续血管成像的比较,以确定血管膨胀和血管收缩.
扩散血管扩张的定义是威利斯圆的≥4个动脉的扩张,而没有"串珠"的外观.

主要成果:

30% (45/148) 的RCVS患者出现了早期的扩散性脑血管扩张.
血管扩张发生较早 (2.25天与头痛发作后的7.63天相比) 并与远部血管收缩有关.
血管扩张的患者患上下关节和内出血的风险更高,女性和二次RCVS中更频繁.

结论:

早期的大脑血管造影可以揭示RCVS中扩散的大脑血管扩张.
大脑血管扩张可能在RCVS病理生理学中发挥作用,影响临床表现和预后.
识别早期的血管扩张对于了解RCVS和管理患者结果至关重要.

Vascular Spasm

Vascular Spasm

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...

Antihypertensive Drugs: Vasodilators

Antihypertensive Drugs: Vasodilators

Vasodilators, primarily affecting the smooth muscles within arterial and venous walls, are commonly used for hypertension treatment. Medications such as minoxidil and hydralazine primarily target arteries and arterioles, while sodium nitroprusside acts on arterioles and venules. Minoxidil, functioning as a prodrug, is metabolized by hepatic sulfotransferase into its active form, minoxidil sulfate, after oral administration. This metabolite binds to the sulfonylurea receptor (SUR) component of...
