  • Title: Brain arteriovenous malformations.
    Author: Ferrara AR.
    Journal: Radiol Technol; 2011; 82(6):543MR-56MR. PubMed ID: 21771938.
    Abstract:
    An arteriovenous malformation (AVM) is a particular abnormality of blood vessels. Brain AVMs are congenital, but symptoms usually do not appear until the second decade of life - if at all. The most common presenting symptom is a brain hemorrhage, but other possible symptoms include neurological deficits, seizures and headaches. Until recently, the gold standard for diagnosing AVM was conventional angiography. However, computed tomography and magnetic resonance angiography are now the first-line diagnostic tools for AVMs. This article reviews the presenting symptoms, diagnostic procedures and treatment options for brain AVMs, including embolization, micro-surgery and radiosurgery.
