Pathophysiology and treatment of brain AVMs.
Cerebral arteriovenous malformations (AVMs) are a major source of intracerebral hemorrhage in younger adults. First, some basic ideas about AVM anatomy, the influences of pressure, macrovascular flow, perfusion and the "steal effect", and some recent observations in the field of inflammatory markers and genetics are briefly discussed. Then, some clinical aspects in the presentation and the natural course of AVMs are highlighted, with special emphasis on the prediction of hemorrhage. Finally, some problems of the current treatment options are mentioned, and future directions in diagnostics and therapy considered.
