Understanding an AVM, and the options for managing it
An arteriovenous malformation (AVM) is a tangle of abnormal blood vessels. Dr. Rajesh Pathi will explain what yours means, what the risks are, and what the choices are, including careful monitoring.
When to seek emergency care. Sudden severe headache, a seizure, weakness, trouble speaking or loss of consciousness need emergency care. Call 108 or go to the nearest emergency department.
An AVM diagnosis is frightening, but there are clear steps to take
AVMs are uncommon and each one is different. Some are found by chance; others come to attention after a seizure or bleed. The first step is a careful assessment of your particular AVM.
Understanding AVMs
General information to help you ask the right questions.
What is an AVM?
A tangle of blood vessels in which arteries connect directly to veins, bypassing the usual small vessels between them.
How are they found?
Often through a scan done for a seizure, headaches or another reason, and sometimes after a bleed.
Why do they matter?
Because of the risk of bleeding and, in some people, seizures or other symptoms.
Can they be treated?
There are several approaches, and in some cases careful observation. The choice depends on the AVM and the person.
What shapes the recommendation
Size & position
Where the AVM sits and how large it is affect both risk and options.
Bleeding history
Whether it has bled before is an important part of the assessment.
Symptoms
Seizures, headaches or other symptoms are considered.
Your health
Age and general health are part of the discussion.
