What is an AVM? How do they develop?
Bleeding from a brain AVM, or an aneurysm associated with it, is usually a neurosurgical emergency.
Brain AVM may never bleed but can be associated with other neurological symptoms such as seizures.
The removal of a brain AVM offers a highly-effective means to prevent haemorrhage in appropriately selected cases.
Smaller AVMs may, be reliably obliterated over time by precisely focussed beams of radiation.
Materials desired via a catheter seek to obstruct flow through an AVM or occlude associated aneurysms.
