Arteriovenous Malformation (AVM) Patient Story

A 12-year-old girl experienced sudden onset of a severe headache. CT scans showed bleeding in her brain caused by arteriovenous malformation (AVM), an abnormal connection between the arteries and veins in the brain.

To stop the bleeding, Norton Neuroscience Institute neurosurgeons performed an embolization, in which a micro-catheter was inserted through an artery in the leg to the AVM. The AVM was then completely filled with special surgical glue used to stop the bleeding and surgically removed.

Removal process:


  • CT scan shows bleeding in the brain (arrow).

Micro-catheter directed into AVM Microcatheter contrast injection shows AVM
Embolization: AVM is completely filled with sugical glue
  • Microcatheter is inserted into the AVM (arrow denotes tip of catheter)
  • Angiogram through the microcatheter clearly shows the AVM nidus
