Arteriovenous Malformations (AVM)
Arteriovenous malformations are tangles of abnormal blood vessels that can occur in the brain. These can be found without any symptoms or can be a cause of headaches or seizures. In some cases, AVMs can cause life-threatening bleeds.
AVM can be treated with surgery, often with endovascular embolization done before surgery to minimize bleeding during the surgery, endovascular embolization alone, or gamma knife radiosurgery. The right treatment depends on the individual AVM, and Hoag interventional neuroradiologists work closely alongside Hoag Neurosurgeons to determine which treatment is right for each patient.
