Surgical Strategy for Sylvian Fissure Arteriovenous Malformations

Abstract

We report three cases of the sylvian fissure arteriovenous malformation (sylvian fissure AVM). The sylvian fissure AVM was a circumferential or penetrating type of AVM and many short feeding arteries of less than 1 mm were directly branched from the middle cerebral arteries (M2, M3). Preservation of the parent and transit arteries of the middle cerebral arteries was the most important goal of the operation.
