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, potentially having an immunological function, but more broadly a dispersive role for neural and blood-derived messengers.

The Virchow–Robin space is a continuation of the [[subarachnoid space]] and varies considerably in depth by species 

[[Cisternostomy]] is a technique that incorporates knowledge of [[skull base surgery]] and micro[[vascular]] [[surgery]]. By opening the brain [[cistern]]s to atmospheric pressure, the technique could decrease the [[intracranial pressure]] due to a backshift of the [[cerebrospinal fluid]], from the swollen [[brain]] to the [[cistern]]s through the [[Virchow Robin space]]s.
