The Department of Neurosurgery, in collaboration with the Radiation Oncology Service, perform stereotactic radiosurgery treatments for the treatment of brain tumours.
With this technique, a large quantity of therapeutic radiation is deposited in a small, well-defined volume of intracranial tissue, with a very low incidence of associated complications.
Its use in pathologies that have been confirmed to benefit from its use to date makes it a very valuable resource.
The pathologies that could be treated with this technique are: neuromas of the acoustic nerve, metastatic lesions, vascular malformations, arterio-venous fistulas, carotid-cavernous, meningiomas, and lesions of the base of the skull, among others.
The hospital has a Brain Tumour Committee made up by a multidisciplinary team of professionals (neurosurgery, radiation oncology, interventional radiology, radiation physicists, etc. ) that provide treatment, especially radiosurgery, for patients with very advanced brain and neurological tumours.
The IVO uses a particle (photon) accelerator as a source of radiant energy. These photons are deposited to cover all of the planned volume through a micromultileaf system that controls the passage of the radiation, so the treatment “fits” very closely with the three-dimensional limits of the lesion in question. This sophisticated mechanism requires a special computer programming system called IPLAN by BrainLab©, which gathers the information from the diagnostic images (MRI + CT + PET) and allows specialists to calculate the spatial co-ordinates and dose with the precision that defines this kind of therapy. In order to do so, a BrainLab radiosurgical framework is placed around the patient’s head, to ensure accurate administration of the dose.
