Made up of surgeons dedicated to their profession, our team strives to achieve excellent results for patients through the most advanced diagnostic and treatment methods.
Our centre offers a multidisciplinary clinical service through the collaboration of different specialities brought together in neuro-oncology and neurovascular boards;
- Neuro-oncology – benign and malignant brain tumours
- Neuroradiology – implantation and embolisation
- AVM (arteriovenous malformation)
- Aneurysms
- Carotid stenosis – advanced neuroradiological examination methods
- Tractography
- Spectrometry
- DTI (diffusion tensor imaging)
- Neurology – DBS (deep brain stimulation)
- Pain modulation
- blocking
- VNS (vagus nerve stimulation)
- Radiosurgery (CyberKnife)
- Neurovascular surgery – aneurysms
- AVM (arteriovenous malformation)
- Cavernoma
- Comprehensive Spine Centre – degenerative spinal diseases – lumbar and cervical disc herniation (microsurgery)
- Degenerative spinal deformities
- Spinal and spinal cord tumours
- Trauma
- Metabolic disorders – osteoporotic spine
- Peripheral nerve surgery
- Brachial plexus surgery
"Stereotactic brain biopsy"
In cases where surgical removal is not absolutely indicated but where the brain lesion must be diagnosed in order to define the best treatment, stereotactic brain biopsy is a relatively safe and reliable method of obtaining diagnostic tissue. Our neurosurgery team has acquired extensive experience of this advanced diagnostic technique. The risks associated with stereotactic brain biopsy are minimal.
