A perivascular space, also known as a Virchow–Robin space, is a fluid-filled space surrounding certain blood vessels in several organs, including the brain, [1] potentially having an immunological function, but more broadly a dispersive role for neural and blood-derived messengers. [2]

2024年11月13日 · Perivascular spaces, also known as Virchow-Robin spaces, are fluid-filled spaces that surround small arterioles, capillaries and venules in the brain. Those that surround perforating vessels are frequently seen on routine MRI imaging.

2020年2月24日 · Here, we review perivascular space anatomy, physiology and pathology, particularly as seen with MRI in humans, and consider translation from models to humans to highlight knowns,...

Perivascular spaces (PVSs), also known as Virchow-Robin spaces, are pial-lined, fluid-filled structures found in characteristic locations throughout the brain. They can become abnormally enlarged or dilated and in rare cases can cause hydrocephalus.

Perivascular spaces include a variety of passageways around arterioles, capillaries and venules in the brain, along which a range of substances can move. Although perivascular spaces were first identified over 150 years ago, they have come to prominence recently owing to advances in knowledge of the …

2021年11月2日 · 血管周围间隙(perivascular space, PVS)，又称V-R(Virchow-Robin)间隙，为血管周围淋巴间隙，PVS是神经系统内的正常解剖结构。 大量临床资料表明EPVS见于老年脑、高血压、 糖尿病 、神经变性性疾病、脑白质病变、脑积水、多发性硬化、中枢神经隐球菌感染、儿童脑 …

In this review, Ineichen and colleagues summarize the role of the perivascular space in neuroinflammation including involved cell types and how those spaces can be visualized. Based on this, they propose a model of the cascade of events during neuroinflammation.

Perivascular spaces (PVS) (also known as Virchow–Robin spaces (VRS)) are fluid-filled spaces that ensheath the pial arteries, pre-capillary arterioles that reside in the subarachnoid space (SAS) and dive deep into the brain and the effluxing pial post-capillary venules and veins as they exit the brain parenchyma back to the SAS and eventually ...

2023年5月10日 · Perivascular spaces (PVS) (also known as Virchow–Robin spaces (VRS)) are fluid-filled spaces that ensheath the pial arteries, pre-capillary arterioles that reside in the subarachnoid space (SAS) and dive deep into the brain and the effluxing pial post-capillary venules and veins as they exit the brain parenchyma back to the SAS and eventually to...

2022年11月2日 · The perivascular space is defined as the compartment surrounding the brain’s blood vessels—its arteries, arterioles, venules, and veins 5 (see Box 1 for definitions). There is a large body of historical and contemporary literature assessing the exact anatomical configuration of perivascular spaces, with considerable inconsistencies across ...
