Intracranial angioplasty is used to widen blood vessels in the brain. A blood vessel can be narrowed due to vasculitis which is an inflammation of the vessel due to arthrosclerotic disease and to vasospasm. Angioplasty is used for focal stenosis secondary to arthrosclerotic disease and to also to vasospasm that often occurs after an aneurysm has ruptured and there has been subarachnoid hemorrhage.
