Fluid mechanics in the perivascular space

Journal of Theoretical Biology, 2011
Perivascular space (PVS) within the brain is an important pathway for interstitial fluid (ISF) and solute transport. Fluid flowing in the PVS can affect these transport processes and has significant impacts on physiology. In this paper, we carry out a theoretical analysis to investigate the fluid mechanics in the PVS.

Is There a Connection Between Perivascular Space and Subarachnoid Space?

Journal of Computer Assisted Tomography, 2014
Perivascular spaces (PVSs) surrounding the walls of arteries, arterioles, and venules do not directly communicate with subarachnoid spaces. There are a few reports exhibiting subarachnoid hemorrhage (SAH) and intracerebral hematomas extending to the PVSs by leakage of the leptomeninges that surround arteries.

Phylogenesis of the Perivascular Spaces of the Brain

Nature, 1947
According to recent, investigations by Van Rijssel1 on a species of carp (Carassius Gibelio), the perivascular spaces penetrate throughout the brain. Cerebrospinal fluid circulates in the spaces, and thus the external and internal liquors mix. This circulation goes in the same direction as the blood circulation and is created by the pulse wave.

The perivascular spaces of ovine and canine brains

New Zealand Veterinary Journal, 1994
Abstract The specialised histology and anatomy of the central nervous system (CNS) is reflected in its pathology. This is particularly so for the perivenular/periarterial spaces in which inflammatory cells accumulate in inflammation. These spaces, although structurally not lymphatics, act as lymphatics draining fluid from brain to subarachnoid space ...

Dilated Perivascular Spaces

2017
A perivascular space (PVS) or a Virchow-Robin space is a typically narrow tract that is the drainage pathway for the cerebral parenchyma. As there is no lymphatic system within the cerebrum, the PVSs drain interstitial/extracellular fluid peripherally outward to the subarachnoid space (SAS) but are thought not to communicate directly with the SAS.
