Brain arteriovenous malformations

Abstract

The diagnostic evaluation of a brain arteriovenous malformation requires a thorough understanding of the imaging features seen on CT, MR, and conventional angiography. Therapeutic planning requires a comprehensive understanding of the angioarchitecture of AVMs, necessitation selective and superselective angiography in order to give an accurate assessment of the lesion. This article will discuss the diagnostic work-up of AVMs. AVM treatment requires a multidisciplinary approach that includes interventional neuroradiology, radiosurgery, and neurosurgery. The considerations and philosophies of each discipline will discussed in order to provide the perspective required for the comprehensive treatment of AVMs.
