Arteriovenous malformations

Arteriovenous malformations

Arteriovenous malformations, also called AVMs, are a potentially life-threating neurological disease. Tangles of abnormal vessels that may occur anywhere in the brain or spinal cord, arteriovenous malformations can cause headaches, loss of language or motor function, seizures, coma, and occasionally death. About 1 percent of people in the U.S. have arteriovenous malformations.

Leonardo Rangel Castilla, M.D., a vascular and endovascular neurosurgeon at Mayo Clinic in Rochester, Minnesota, discusses considerations used to determine the appropriate treatment for patients and the three types of treatments used to manage arteriovenous malformations safely: microsurgery, endovascular embolization and radiation.

At Mayo Clinic, multidisciplinary teams of neurologists, neurosurgeons and interventional radiologists use the latest technology to tailor treatment of arteriovenous malformations to each individual patient.
