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 […]
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 [...]
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, [...]
Trigeminal Neuralgia: what it is, its symptoms, and the main treatment options.
Trigeminal neuralgia (TN) is one of the most painful neurological conditions a person can suffer from. Over more than forty years of professional practice as a neurosurgeon, I have been able to observe the profound impact this illness has on the quality of life of those who suffer from it. An accurate diagnosis and a [...]
Arnold-Chiari malformation: diagnosis and surgical treatment
In this new post, we'll talk about Arnold-Chiari malformation, a complex neurological condition characterised by the displacement of brain tissue, specifically the cerebellar tonsils, into the spinal canal. This condition can generate a variety of symptoms due to the compression of the brainstem and spinal cord, as well as the […]
Minimally Invasive Neurosurgery (MIS): Latest Trends and Advances
Today we're going to talk about how minimally invasive surgery (MIS) neurosurgery has undergone a significant transformation in recent decades, emerging as a fundamental pillar in the treatment of various brain and spinal conditions. This evolution has been driven by the constant pursuit of safer, less traumatic procedures with faster recoveries […]
Endoscopic technique in pituitary tumours: advantages and recovery
Today we will discuss how endoscopic techniques have revolutionised the surgical approach to pituitary tumours, offering a minimally invasive alternative to traditional surgery. This procedure allows neurosurgeons to access the pituitary gland via the nasal passages, avoiding cranial incisions and significantly reducing surgical trauma. The evolution of this [...]
