what is a vasospasm in brain
A cerebral vasospasm is the term used to describe when a brain artery or smaller brain blood vessels narrow. A blood vesselâs central lumen becomes narrow in response to the vessel wall contraction. This constriction prohibits blood flow.
Delayed cerebral ischaemia. Delayed cerebral ischaemia, or vasospasm, is another serious and common complication of a subarachnoid haemorrhage. This is when the supply of blood to the brain becomes dangerously low, disrupting the normal functions of the brain and causing brain damage. It's most common a few days after the first haemorrhage.
