The arteriovenous malformation (AVM) is a vascular malformation characterized by fistulas between arteries and veins forming a nidus, without interposition of capillary vessels and of which early draining vein is identified at the digital angiography. Potential reports of its existence date from the second century AD. Spetzler and Martin (S-M) proposed a classification considering three features and Lawton then added new predictors. A maximum of 10 score can be achieved by applying the modified S-M grade system. This classification guides decision-making and the possible choice of the multimodal treatment (surgery, radiosurgery and embolization). We discuss historical, pathological, clinical and therapeutic …

Clinical Applications Of Direct Cortical Stimulation During Awake Craniotomies. Commentary On Passive Functional Mapping Using Infrared Thermography In Epilepsy Awake Surgery., Ramiro Antonio Perez De La Torre, Ramanathan Siddarth, Pérez Ramírez Pedro, Santiago Noé

Archives of Neurosurgery

As clinicians, we rely on various imaging methods to identify abnormal brain lesions. We can distinguish this myriad of neurological disorders by using imaging alone or together with either or both electrophysiological monitoring and direct cortical stimulation. This last alternative is the most frequently used approach to diagnosing brain lesions requiring awake craniotomies for adequate management. Awake craniotomies have become the standard of care for focal lesions, including vascular malformations like cavernous angiomas, intrinsic brain tumors, gliomas, vasculitic brain lesions, postinfectious brain lesions, brain metastasis, and also for epilepsy surgery. Surgery for epileptic patients requires multidisciplinary team interactions and a …

The Scientific Divulgation In Neurosurgery., Rodrigo Ramos-Zuñiga, Sergio Manuel Ibarra-Navarro

Archives of Neurosurgery

The communication of scientific findings in a young discipline in the evolution of knowledge about the human nervous system, has had a consistent and significant advance. This interdisciplinary and multidisciplinary vision has been a fundamental educational axis in the development of neurosurgery in terms of innovation, scientific progress, technological development and quality of patient care. It is therefore essential that scientific writing and communication channels continue to preserve these quality standards, to validate without bias and with certainty, the value and strength of the advances of neurosurgery as a science.

Microvascular Decompression For Hemifacial Spasm: Surgical Technical Nuances And Results After 300 Microvascular Decompression Surgeries, Rogelio Revuelta Gutiérrez, Miguel Vega-Arroyo, Olivia L. Vales-Hidalgo, Cynthia E. López-Rafael, Jesús Martínez-Manrique, Sergio Moreno Jiménez

Archives of Neurosurgery

Introduction: Hemifacial spasm (HFS) is characterized by the involuntary, paroxysmal, painless, and progressive spasmodic contractions of facial muscles innervated by the ipsilateral seventh cranial nerve. To date, neuroimaging studies (Computed Tomography scan [CT] and Magnetic Resonance Imaging [MRI]) are unable to establish the diagnosis. HFS medical treatment with antiepileptic drugs, and Botulinum toxin application are temporarily effective, however, both have shown side effects and lesser cost-effective results. Currently, surgical Micro Vascular Decompression (MVD) for HFS has the highest curative rates and lower operative morbidity. We analyze the demographics, clinical manifestations, outcomes, and complications that to our knowledge, is the largest …

Passive Functional Mapping Using Infrared Thermography In Epilepsy Awake Surgery: Case Report, Enrique De Font-Réaulx, Javier Terrazo-Lluch, Paul Shkurovich-Bialik, Miguel Ángel Collado-Corona, Ernesto Ramírez-Navarrete, Luis Díaz-López Md, Alma Rosa Martínez-Rosas Msc, Adalberto González-Astiazarán

Archives of Neurosurgery

Background: Active Functional Mapping (AFM) is the gold standard method for localizing cortical and subcortical brain functional areas and tracts. By definition, it requires direct application of controlled electrical stimuli under established protocols. Nevertheless, it entails inherent risks, such as causing intraoperative seizures. On the other hand, Passive Functional Mapping (PFM) doesn´t require electrical stimulation of the nervous system. PFM is based on the knowledge that brain metabolism generates different electromagnetic radiation patterns depending on its metabolism, that are invisible to the human eye, but infrared thermographic cameras can show those changes related to brain activity without the use of …

The Sellar Barrier’S: An Important New Concept In Pituitary Surgery., Juan F. Villalonga, Alvaro Campero

Archives of Neurosurgery

The sellar barrier's concept was created by our team in Tucumán in 2019. There are currently 3 well-defined subtypes: strong, weak and mixed. Published case series studies indicate that there is a strong correlation between radiological, intraoperative findings and risk of cerebrospinal fluid (CSF) leakage. Patients with weak sellar barrier have more risk of intraoperative CSF leak. The strong sellar barrier is a protective factor for intraoperative CSF leak. The sellar barrier's concept is useful for clinical-surgical practice and for the physician-patient relationship.
