Cirugía de hipófisis: mínima invasividad mediante abordaje endonasal
La hipófisis es una glándula del tamaño de un guisante situada en la base del cráneo, justo detrás de la nariz, que actúa como el centro de mando del sistema endocrino. A pesar de su reducido tamaño, regula funciones tan diversas como el crecimiento, la producción de hormonas tiroideas, la función suprarrenal o la producción […]
Innovación tecnológica: la realidad aumentada al servicio de la neurocirugía
La neurocirugía ha vivido en las últimas décadas una transformación impulsada por la tecnología, y la realidad aumentada se ha convertido en una de las herramientas más prometedoras dentro del quirófano. Esta técnica permite superponer imágenes generadas por ordenador procedentes de resonancias magnéticas, tomografías computarizadas o angiografías, directamente sobre el campo quirúrgico real. De este […]
Hemifacial Spasm: Causes and Treatment Options
Hemifacial spasm is a neurological disorder that causes involuntary and repetitive contractions in the muscles of one side of the face. Although in its early stages it can manifest as a slight tremor around the eye, over time it can spread to the cheek, mouth, and even the neck, eventually affecting […]
Back care on holiday: tips to avoid summer injuries
Summer is a time yearned for by many, synonymous with rest, adventures, and a break from the daily grind. However, this change in habits often comes with activities and postures that can put the health of our spine at risk. From long car journeys to water sports or simply relaxing [...]
Skull Base Surgery: Pushing the Boundaries of Neurosurgery
The base of the skull is one of the most complex and delicate regions of human anatomy. It is the bony structure that separates the brain from the sinuses, orbits, ears, and cervical spine. Vital arteries, major draining veins, and the twelve pairs of […]
MAV Cerebral: A Challenge for Modern Vascular Neurosurgery
Cerebral arteriovenous malformations (AVMs) represent one of the most complex and fascinating pathologies within the field of vascular neurosurgery. They are congenital abnormalities consisting of a direct and anomalous connection between arteries and veins, without the interposition of a normal capillary bed. This structure, termed a «nidus,» subjects the cerebral veins to [...]
CyberKnife Radiosurgery: sub-millimetre precision for brain pathologies
The evolution of neurosurgery in recent decades has been characterised by the relentless pursuit of maximum therapeutic efficacy with minimal invasiveness. In this context, stereotactic radiosurgery has established itself as an indispensable tool, and the CyberKnife system represents the pinnacle of this technology. At the Arráez Institute, we are proud to offer […]
Chronic hydrocephalus in adults: a treatable cause of dementia in adults
The ageing of the population leads to the appearance of pathologies that can sometimes be confused with irreversible degenerative processes. One of the most relevant conditions in this context is Normal Pressure Hydrocephalus (NPH), also known as Hakim-Adams syndrome. At Instituto Arráez, we consider the correct identification of this pathology to be fundamental, as [...]
Normal pressure hydrocephalus: a treatable cause of dementia in adults
The ageing of the population leads to the appearance of pathologies that can sometimes be mistaken for irreversible degenerative processes. One of the most relevant conditions in this context is normal-pressure hydrocephalus, also known as Hakim-Adams syndrome. At the Arráez Institute, we consider the correct identification of this [condition] to be fundamental.
Cerebral Aneurysms: Early Diagnosis and Treatment as Key Factors
A cerebral aneurysm is a localised widening or bulging in the wall of an intracranial artery. This protrusion, resembling a small balloon, occurs due to a structural weakness in the muscular layer of the blood vessel. Although many aneurysms may remain asymptomatic throughout a person's life, the primary risk lies in their potential rupture, [...]
