Arteriovenous Malformations: A Diagnostic and Therapeutic Challenge

Many dermatologists are largely unfamiliar with arteriovenous malformations (AVMs). This is partly due to the low prevalence of these lesions and to the fact that they are generally managed by other specialists, in particular, interventional radiologists and pediatric, maxillofa- cial, and plastic surgeons. In this article, we review the recommended nomenclature for AVMs and look at their clinical manifestations and diagnosis, as well as the ideal type and time of treatment. AVMs should be managed from a multidisciplinary approach, and the dermatologist's primary goal should be to make a proper diagnosis and thereby avoid unnecessary treatments. © 2012 Elsevier Espana, S.L. and AEDV.
