Treatments and drugs

By Mayo Clinic Staff

Surgery is usually needed to remove a spinal AVM from surrounding tissue.

Before surgery, your doctor may recommend endovascular embolization. This is a procedure to reduce the chance of bleeding during surgery or reduce the size of the AVM so that surgery is more successful.

In endovascular embolization, a catheter is inserted into an artery in your leg and threaded to an artery in your spinal cord that is feeding your AVM. Small particles of a glue-like substance are injected to block the artery and reduce blood flow into the AVM.

If the AVM can't be completely removed surgically, your doctor may recommend radiation therapy to shrink the lesion.
