Cerebrovascular conditions refers to a variety of problems which can affect the bloodflow to or from the brain. These include cerebral aneurysms, stenosis (narrowing), and arteriovenous malformations (AVMs).
Many cerebrovascular conditions don’t cause symptoms (they are asymptomatic), however in some cases they may cause problems by bleeding or obstructing blood supply to the brain. The result can be a haemorrhage or a stroke.
In general, the treatment of cerebrovascular conditions is determined by weighing up the risk of treating the problem with the risk of not treating it.
