Anatomical bases of the periinsular hemispherotomy
Keywords:
HEMISPHERECTOMY, CEREBRAL CORTEX
Abstract
Introduction: hemispherectomy is used as a surgical treatment in selected patients with uncontrollable partial seizures associated with progressive motor deficit. This technique has been modified towards disconnective treatments, with preservation of the parenchyma (hemispherotomy). The first important modification was made by Rasmussen, who described the functional hemispherectomy. In 1992, Delalande described the hemispherotomy and, in 1995, Villemure and Mascott performed the periinsular hemispherotomy. Objective: to show from the anatomical point of view the fascicles of white matter interrupted in the periinsular hemispherotomy. Material and method: seven cerebral hemispheres from adult cadavers were used. In two, axial, sagittal and coronal sections were made; five were dissected using the Klingler technique. Results: the periinsular hemispherotomy begins with the suprainsular window. Through it, the fibers of the corona radiata-internal capsule transition are sectioned. An endoventricular callosotomy, frontobasal resection and anterior white commissure resection are then performed. In the second step (infrainsular window) the temporal peduncle and trigone are sectioned and the temporomesial structures are resected. All fascicles and anatomical structures resected or sectioned were revealed by dissection, which allows a full three-dimensional conception of the procedure.
