It's important to get medical attention for an AVM as soon as
possible. Often, immediate treatment may help avoid serious
complications of some AVMs. Current surgical methods make treatment for
AVM safer and more effective than ever. The goal of treatment is to stop
the flow of blood within the AVM.
Surgical resection removes the tangled blood vessels.
-
Reaching the brain: The surgeon uses a procedure called
craniotomy to reach the brain. During a craniotomy, small holes called
burr holes are made in the skull. The bone between the holes is cut and
lifted away. Finally, the surgeon opens the dura and exposes the brain.
-
Removing the AVM: Once the surgeon has access to the AVM,
the abnormal arteries and veins are removed. This redirects blood flow
to normal vessels, preventing the AVM from bursting and leaking blood.
-
Closing the skull: When the AVM has been removed, the dura
covering the brain is closed. In most cases, the skull bone is put back.
The skull bone can be held in place using one of several methods.
Titanium clamps are often used, as they provide the most stability and
cover the burr holes. After the clamps are in place, the skin incision
is closed with stitches or staples.
