Surgical [[revascularization]] decreases the long-term [[stroke risk]] in [[child]]ren with [[moyamoya disease]] but can be associated with an increased [[risk]] of [[stroke]] during the [[perioperative]] [[period]].
----
Intracranial [[stenosis]] is the severe narrowing of an [[artery]] within the [[skull]]. A blood vessel narrows when fatty deposits (plaque) build up inside the vessel, a condition known as [[atherosclerosis]]. Stenosis can restrict [[blood flow]] to areas of the brain, increasing the risk of [[stroke]].
----
The VERiTAS study is the first [[prospective]] study of haemodynamics and [[stroke]] [[risk]] in the [[posterior circulation]]. The results may impact the selection criteria for interventional candidates and also define a low-risk population in whom the risks of invasive interventions would be unnecessary
