SOLE, Horacio A. Microanatomía de las malformaciones arteriovenosas: Consideraciones quirúrgicas. Rev. argent. neurocir. [online]. 2006, vol.20, n.3, pp.137-142. ISSN 1850-1532.

Arterio-venous malformations (AVM) are a complicated pathology that raise important dilemmas in their treatment. Direct surgery is one of the principal therapeutic options and, for its correct accomplishment it is necessary to know their architecture and microanatomy. They consist of 3 portions: afferent or arterial, nest and efferent or venous. The characteristics of each one of them and the surgical steps that, in the experience of the author, are useful for the surgical resection are described. The possible complications that can appear during surgery are mentioned and also how to solve them. The need to evaluate, as exhaustively as possible, magnetic resonance images and preoperative angiography, to choose the best surgical strategy is emphasized.
