Microsurgical Anatomy of the Insular Region and Operculoinsular Association Fibers and its Neurosurgical Application
2019
Objective To analyze the three-dimensional relationships of the operculoinsular compartments, using standard hemispheric and white matter fiber dissection and review the anatomy of association fibers related to the operculoinsular compartments of the Sylvian fissure and the main white matter tracts located deep into the insula. The secondary aim of this study was to improve the knowledge on this complex region to safely address tumor, vascular, and epilepsy lesions with an integrated perspective of the topographic and white matter fiber anatomy using 2D and 3D photographs. Methods Six cadaveric hemispheres were dissected. Two were fixed with formalin and the arteries were injected with red …
Gyral and Sulcal Microsurgical Anatomy
2019
Abstract The complex set of sulci and gyri on the surface of the brain form a map with which neurosurgeons should be familiar when it comes to planning and carrying out their procedures, more particularly in the case of intrinsic brain lesions. Based on the general organization of the lobes and gyral convolutions of the brain, as defined by sulci and fissures, the pre- and intraoperative identification of the anatomical features of each patient is of critical importance. Knowledge of brain morphology is also essential to identify its different functional areas, given that both are closely associated. The correct interpretation of the excellent imaging techniques that are currently available…
Cisternostomy for Traumatic Brain Injury: A New Era Begins
2016
Traumatic brain injury (TBI) is a major cause of death and disability especially in the young generations. In the United States TBI affects about 1.7 million people annually [1] and this number is higher in the developing countries. It is well known that TBI is associated to a primary and secondary brain injury. The first is without solution and depends on the impact. In surviving patients, what plays a critical role is the subsequent secondary injury since, without effective treatments, complex cascades will promote additional brain damage.
The Transcallosal Anterior Interfoniceal Approach: A Microsurgical Anatomy Study
2014
Objectives: A plethora of surgical strategies have been described to reach deeply lesions situated within the third ventricle, including the Rosenfeld or anterior transcallosal interfoniceal approach (TAIF). Firstly, introduced in 2001, it consists of a small callosotomy followed by the midline transseptal dissection of fornices to enter the roof of the third ventricle. The aim of this microsurgical anatomy study is to describe and show each stage of the surgical procedure, focusing on the possible trajectories to anatomic landmarks. Participants: A total of twenty adult cadaveric specimens were used in this study. Using x3 to x40 magnifications the surgical dissection was carried out in a …
