Brain Arteriovenous Malformations (AVM)
An arteriovenous malformation (AVM) of the brain is a complex condition requiring specialist, multi-disciplinary expertise to manage. Although many are present without causing symptoms AVM is a cause of stroke and epilepsy in young people. These pages are written and medically reviewed by Dr Daniel Walsh.
What is a Brain AVM?
What is an AVM? How do they develop?
Bleeding from Brain AVM
Bleeding from a brain AVM, or an aneurysm associated with it, is usually a neurosurgical emergency.
Unruptured AVM
Brain AVM may never bleed but can be associated with other neurological symptoms such as seizures.
Microsurgical Treatment
The removal of a brain AVM offers a highly-effective means to prevent haemorrhage in appropriately selected cases.
Radiosurgery
Smaller AVMs may, be reliably obliterated over time by precisely focussed beams of radiation.
Endovascular Embolisation
Materials deposited via a catheter seek to obstruct flow through an AVM or occlude associated aneurysms.
