Vasospasm refers to a condition in which an arterial spasm leads to vasoconstriction. This can lead to tissue ischemia (insufficient blood flow) and tissue death (necrosis).
Along with physical resistance, vasospasm is a main cause of ischemia. Like physical resistance, vasospasms can occur due to atherosclerosis. Vasospasm is the major cause of Prinzmetal's angina.
Cerebral vasospasm may arise in the context of subarachnoid hemorrhage as symptomatic vasospasm (or delayed cerebral ischemia), where it is a major contributor to post-operative stroke and mortality. Vasospasm typically appears 4 to 10 days after subarachnoid hemorrhage, however the relationship between radiological arterial spasm (seen on angiography) and clinical neurological deterioration is nuanced and uncertain.
