Introducción: Las herramientas para el entrenamiento del neurocirujano en formación ha ido en aumento en la actualidad; con el impulso de la ciencia, nuevas tecnologías permiten el desarrollo de la parte experimental en este campo. Estudios informan sobre la mejora en el rendimiento del especialista mientras más tiempo cursa en el laboratorio. En nuestro país no existe actualmente un programa escolarizado para la simulación y experimentación en neurocirugía, por lo que este trabajo sería la primera piedra en la constitución de los mismo. Objetivos: el objetivo principal es determinar el impacto del uso de simulación para el entrenamiento en neurocirugía vascular mediante modelos de simulación y experimental; además de documentar el paso a paso para poder desarrollar investigación a partir de ello. Diseño: El estudio será de tipo intervencionista prospectivo. Y será llev...

Introduction: Head trauma is one of the main causes of death in Peru. Medical and surgical therapy during the initial stages of severe head trauma focus in preventing the elevation of intracranial pressure. Objective: To describe the associated characteristics and main complications in patients undergoing decompressive craniectomy. Methods: This is a retrospective observational study performed between February 2018 and July 2020 in patients who had been admitted because of head trauma and who had undergone unilateral decompressive craniectomy. Results: Two-thirds (66.7%) of patients were persons less than 40 years of age; 87.5% were males; 16.7% were admitted with Glasgow Coma Score (GCS) scores between 13 and 15; 37.5% were admitted with GCS between 9 and 12; 42.9% had asymmetric pupils; 33.3% were admitted because of traffic accidents; 21.7% were Marshall II, 65.2% were Marshall III, a...

Low-grade fibromyxoid sarcoma (LGFMS) is a soft tissue tumor of mesenchymal origin. Sarcomas are a heterogeneous group, representing 1% of all neoplasm diagnoses. Primary sarcomas of the central nervous system (CNS) are rare, and represent only 0.7% of all sarcomas, with an estimated incidence of 3 per 10 million people per year. The case of a 59-year-old woman who developed a low-grade intracranial fibromyxoid sarcoma in the right parietal region, is described. The clinical course, imaging studies, histopathological features, and treatment approach of this unusual diagnosis, are discussed. Low-grade intracranial fibromyxoid sarcoma is a rare and probably under- reported condition. The definitive diagnosis is usually made through histo-pathological studies.

Discogenic low back pain is a condition whose typical initial medical management is that of physical therapy. A significant percentage of patients experience a reduction of their discomfort, but for those with persistent symptoms, surgery is recommended. Traditionally, open surgery or microdiscectomy has been the preferred choice for the treatment of herniated discs. Nevertheless, endoscopic discectomy is a technique with several advantages; in this review of third-generation endoscopic discectomy, its indications, a brief history of international and national spinal endoscopy, the technique and its application in our context are described, and a case handled in our institution is presented.

Introducción: Los aneurismas intracraneales representan el 85% de casos de hemorragias subaracnoideas, dentro de las cuales las no traumáticas tienen una alta tasa de mortalidad (40-60%). En el manejo endovascular y microquirúrgico de esta enfermedad, el debate ha sido siempre intenso respecto a si el tratamiento temprano produce un beneficioso resultado funcional y reduce la morbi-mortalidad del paciente. Caso Clínico: Paciente mujer de 54 años, admitida con cefalea súbita y cuadro neurológico que cursó con rápido deterioro. La tomografía mostró hemorragia subaracnoidea por ruptura aneurísmica del complejo comunicante anterior; fue sometida a  microcirugía dentro de las primeras 24 horas y transferida luego a UCI, sin complicaciones. Discusión: El tiempo de resolución, sea mediante clipaje microquirúrgico o tratamiento endovascular...

Rosai-Dorfman Disease  is a rare disorder of unknown etiology. Intracranial presentation is even rarer and often mimics the appearance of a meningioma on neuroimaging. Here we present the case of a 38-year-old male patient admitted for an intracranial, extra-axial, supratentorial tumor associated with mild neurological deficit; the presumptive diagnosis was convexity meningioma. After surgery, the definitive histological diagnosis was informed as intracranial Rosai-Dorfman Disease.The differential diagnosis of any extra-axial intracranial lesion suggestive of a meningioma should include intracranial Rosai-Dorfman Disease due to the similarities on clinical presentation and neuroimaging.

Pott’s disease or tuberculous spondylodiscitis accounts for less than 1% of tuberculosis cases. However, the indolent clinical course of this condition leads to a generally delayed diagnosis and to the destruction of the vertebral structures. The resulting spinal deformity requires surgical treatment, which is complex and demands a prolonged hospital stay. In this report, we present the case of a 52-year-old male patient who was diagnosed with lumbar spondylodiscitis by clinical and imaging studies, without response to an empiric antibiotic treatment. Transforaminal percutaneous approach, a minimally invasive technique, allowed the diagnosis of tuberculous spondylodiscitis and a symptomatic improvement of the patient.
