BACKGROUND One of the most frequent phenomena in the follow-up of glioblastoma is pseudoprogression, present in up to half of the cases. The clinical usefulness to discriminate this phenomenon through magnetic resonance imaging and nuclear medicine is not yet standardized, in this study we used machine learning on multiparametric magnetic resonance...

OBJECTIVE One of the principles of the surgical treatment of craniosynostosis includes the release of fused bone plates to prevent recurrence. Such bone defects require a reossification process after surgery to prevent a cosmetic problem or brain vulnerability to damage. The objective of this study is to describe and analyze the radiological and cl...

Meningiomas are the most common primary intracranial tumors. Since the adhesions in the plane of dissection are of interest in surgical planning, we suggest that digital image subtraction of FLAIR data from the T2 sequence of MRI may represent better the CSF spaces in the brain-tumor interface and may be a predictor of the intraoperative cleavage p...

Background Linear accelerator stereotactic radiosurgery is one of the modalities available for the treatment of central nervous system arteriovenous malformations (AVMs). The aim of this study was to describe our 15-year experience with this technique in a single tertiary center and the analysis of outcome-related factors. Methods From 1998 to 201...

Background: Spinal instrumentation using transpedicular screws has been used for decades to stabilize the spine. In October 2018, an intraoperative CT system was acquired in the Neurosurgery service of the University Hospital Complex of Vigo, this being the first model of these characteristics in the Spanish Public Health System, so we began a stu...

Anaplastic Pilocytic Astrocytoma (APA) is a subtype of Pilocytic Astrocytoma (PA) that appears when the tumor shows signs of anaplasia and follow an aggressive clinical course. It is a very rarely tumor, especially in older than 18 years. We made a screening of our data base to find patients who was discharged with the diagnostic of APA and we made...

Intracranial aneurysms are dilations of the arterial walls of the cerebral arteries, their most severe consequence is the aneurysmal rupture causing subarachnoid haemorrhage, an entity of high mortality and that is associated with important sequelae among survivors. The objective of this series of studies was to analyse the risk of rupture of multi...

Hemangiopericytoma and Solitary Fibrous Tumor are tumors with low incidence. They have a tendency to recur locally and to metastasize. The WHO integrated both tumors into a new entity but one of the pending issues is to demonstrate the effectiveness of surgery plus complementary radiotherapy (RT) and standardize the use of it. We reviewed the data...

Background Subdural hematomas are one of the most frequent types of intracranial hemorrhage, but there are very few references to explain how different factors can influence the prognosis of these patients. We have tried to establish with statistical significance several elements that influence the Glasgow Outcome Scale at 12 months of follow-up....

Objectives The treatment of hydrocephalus using external ventricular drainage (EVD) seems to favour rebleeding of an untreated ruptured aneurysm. FSI studies are valuable to study this environment. Patients and methods From December 2014 to December 2017, 61 patients with SAH required EVD due to hydrocephalus, 6 patients had aneurysm rebleeding af...

Introduction and objectives The anterior communicating complex is one the most common locations for aneurysm development. It receives blood from both carotid circulations and the effect of synchrony on the arrival of blood flow has not been previously studied. The objective of this study was to compare the asynchrony conditions of the A1 pulse and...

Spontaneous hematomas associated with spinal meningiomas have been very rarely reported. They have been frequently associated with coagulation disorders or traumatic lumbar punctures. We report a case of a 72-year-old woman without coagulation disorders with a dorsal meningioma at D9-D10 level admitted in our hospital for scheduled surgical treatme...

Background Intracranial aneurysm rupture is associated with a high mortality and disability despite modern medical care. Multiple aneurysms occur in nearly 16% of patients, imaging studies of naturally occurring multiple aneurysms are valuable for computational fluid dynamics studies, in this study we describe and analyze the hemodynamic changes pr...

Objective Posttraumatic hydrocephalus and subdural hygromas are common after traumatic brain injury patients. The aim of the study was to analyze the association of both disorders to primary, secondary decompressive craniectomy (DC) and non-craniectomized patients with moderate and severe traumatic brain injury. Methods From 2010 to 2016, 177 pati...

Resumen Objetivos: Descripción del protocolo diagnóstico y técnica quirúrgica para el manejo de un quiste hidatídico cerebral gigante en una paciente de edad pediátrica. Métodos: Se presenta el caso de una paciente de 8 años de origen marroquí, con historia de cefalea mensual de un año de evolución, exacerbada dos días previo al ingreso y asociada...

Resumen Objetivos: Las series publicadas en relación al glioblastoma multiforme sugieren que una resección máxima es un factor relacionado con mayor supervivencia aunque la extensión de la resección óptima aun no está bien definida en la literatura. Presentamos un análisis de la supervivencia en nuestra población, que por sus características basale...

Objectives: It is common to observe the persistence of extra-axial collections after craniotomies. Most of these disappear in weeks or months but some remain. The onset of focal symptoms or the growth of these persistent collections months or years after surgery may indicate the presence of a chronic and latent infection by germs of low virulence...

Objectives: To determine the incidence and factors associated with cerebrospinal fluid dynamics disorders in patients with moderate and severe traumatic brain injury. Methods: From October 2010 to October 2016, 177 patients were admitted to the Intensive Care Unit of the University Hospital Complex of Vigo with the diagnosis of moderate and severe...

Resumen Objetivos: El manejo perioperatorio de anticoagulantes y antiagregantes es problema común en neurocirugía. El envejecimiento de la población y comorbilidades lo convierten en un reto más frecuente cada día. Revisamos la evidencia actual sobre este tema y proponemos un protocolo de actuación para un servicio de Neurocirugía de un hospital d...

Meningiomas are highly vascularized, extra-axial central nervous system (CNS) tumors that derive blood supply from both extracranial and intracranial circulations. This book reviews risk factors, treatment options and outcomes of meningiomas. Chapter One reviews and discusses recent risk factors of meningioma development. Chapter Two provides an up...
