Arteriovenous malformations (AVMs) are bundles of tangled arteries and veins in the brain or spinal cord. AVMs are present from birth, though it is unclear what causes them.

Some AVMs may never cause any symptoms. Others may cause serious symptoms such as:

  • Bleeding
  • Headaches
  • Loss of speech
  • Memory loss
  • Paralysis
  • Seizures
  • Vision loss

If an AVM bleeds, it can put you at risk for severe neurological problems and even death.

Neurology experts at The University of Miami Health System diagnose and treat AVMs using the latest technology. We work to identify AVMs early to prevent serious complications.

Tests


  • Magnetic Resonance Imaging (MRI)

    An MRI allows your physician to see the blood vessels in your brain and identify any AVMs. Your doctor may use a special dye to see your blood vessels even more clearly.

  • Computed Tomography (CT) Scan

    Computed tomography is a type of X-ray that takes many images of your brain. With the use of special dye, CT scans allow your physician to see the blood vessels in your brain.

Treatments


  • Embolization

    Embolization is an interventional procedure to block blood flow to the AVM. It uses a special type of glue. You may receive embolization to help reduce blood loss.

  • Gamma Knife® Radiosurgery

    Gamma Knife radiosurgery uses precisely targeted beams of radiation to shrink the AVM. The radiation is weak throughout the beams, but strong where all the beams meet. Over time, the AVM shrinks until blood no longer flows through it.

  • Surgery

    A neurosurgeon can treat an AVM by removing the abnormal blood vessels and redirecting blood flow to healthy vessels. This treatment prevents an AVM from bleeding.
