A cerebral vasospasm is the term used to describe when a brain artery or smaller brain blood vessels narrow. A blood vesselâs central lumen becomes narrow in response to the vessel wall contraction. This constriction prohibits blood flow.
Vasoconstriction is a narrowing of the blood vessels resulting from contracting of the muscular wall of the vessels. When blood vessels constrict, the flow of blood is restricted or slowed.It is the opposite of vasodilation, the widening of blood vessels.Factors causing vasoconstriction are called vasoconstrictor, also vasopressors or simply pressors. Vasoconstriction usually results in an increase of the blood pressure.Vasoconstriction may be slight or severe.t is the opposite of vasodilation, the widening of blood vessels.
