Cerebral AV malformations are treated if there is:

  • an expanding haematoma associated with AVM
  • a risk of haemorrhage - especially in young who may bear the AVM for some considerable time
  • poor tolerance of symptoms - except usually unhelpful in resolving epilepsy

Methods of treating the malformation include:

  • surgical - excision of AVM aided by angiography; or occlusion of feeding vessels - less popular today because AVM often shows persistent filling from dilated collaterals; only available with low-grade AVM's
  • selective embolisation of feeding vessels - sponge, muscle, beads, detachable balloons, etc. may be introduced
  • radiotherapy - may be widely used as methods improve
