MARTINEZ, Fernando et al. Bases anatómicas de la hemisferotomía periinsular. Rev. Méd. Urug. [online]. 2004, vol.20, n.3, pp.208-214. ISSN 1688-0390.

Summary Background. Hemispherectomy is a surgical treatment used in selected patients, carriers of partial uncontrolled onset associated with progressive motor deficiency. This technique has evolved to disconnective treatments (hemispherotomy). Rasmussen first described functional hemispherectomy. In 1992, Delalande described hemispherotomy and, in 1995 Villemure y Mascot, peri-insular hemispherotomy. Objective. To anatomically show interrupted serial brain slices by in peri-insular hemispherotomy. Methods. Seven brains of male corpses were used. Axial, sagittal and coronal resections were obtained in two brains, the five left were dissected by Klingler technique. Results. the three-dimensional procedures include interruption of the internal capsule and corona radiata, transventricular corpus callosotomy, disruption of the frontal horizontal fibers and resection of the medial temporal structures. A second step includes sectioning the temporal horn, trígono y se resecan las estructuras temporomesiales. All sectionned fasciculus and anatomical structures were dissected, that allows to figure the three-dimensional procedures.
