A brain arteriovenous malformation or AVM for short, is a tangle of abnormal blood vessels connecting arteries and veins in the brain.
These arteries are responsible for taking oxygen-rich blood from the heart to the brain. Veins carry the oxygen-depleted blood back to the lungs and heart but having a brain AVM can cause disruption to this vital process.
So, How Common Is This Condition?
Believe it or not, it’s a surprisingly rare condition with fewer than 20,000 cases per year in UK.
Does AVM Diagnosis Require a Lab Test Or Imaging?
The size, shape and location of brain AVMs can be detected using imaging tests such as: MRI (magnetic resonance imaging) CT (computed tomography) Cerebral Angiogram MRA (magnetic resonance angiography
Is AVM a Treatable Condition?
AVM is typically considered curable, if the entire ‘nidus’ or tangled blood vessels where arteries and veins connect are removed or disrupted
What Is The Recovery Time?
Like most strokes, recovery can either take up to 7+ years or be lifelong.
So What Causes AVM To Happen?
The exact cause is unknown but it is usually a congenital condition. Most commonly observed symptoms include headache and seizures with surgery being the most commonly suggested treatment option.
Like Ischemic and Haemorrhagic strokes. The younger generation can also experience Brain AVM (Arteriovenous Malformation) attacks.
