Arteriovenous malformations (AVMs), brain tumour treatment


Arteriovenous malformations (AVMs)

Gamma Knife surgery is an increasingly important treatment alternative for arteriovenous malformations (AVMs). So far more than 60,000 AVM therapies have been carried out using Gamma Knife radiosurgery.

What is an AVM?

An AVM is a collection of abnormal blood vessels between the arteries and veins. In most patients it is congenital.

What are the symptoms of an AVM?

More than 60% of AVMs present with a haemorrhage (internal bleed) which can cause anything from a moderate to severe headache as well as neurological problems, such as epilepsy. 

How are AVMs diagnosed?

Normally an MRI will be performed and then detailed evaluation is by performing an angiography.

What is the treatment for an AVM?

Cerebral AVMs are mainly treated using microsurgery, however if the AVM is small, Gamma Knife treatment can be effective. AVMs can also be treated in the short-term by embolisation (using a catheter) following which surgery or Gamma Knife surgery would be required.

Further information on AVMs

Please contact the Gamma Knife Centre directly or go to AVM Support UK.
