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 our patients access to this treatment modality, which allows us to address brain and spinal lesions with unprecedented precision, without the need for incisions or general anaesthesia.
Unlike conventional radiotherapy which delivers low doses of radiation in multiple sessions over weeks, lCyberKnife radiosurgery It delivers exquisitely focused high-energy radiation beams to the target. The system uses a highly flexible robotic arm and a real-time image-guidance system that compensates for even the subtlest patient movements, such as breathing, ensuring that surrounding healthy tissue receives a minimal radiation dose.
What pathologies can be treated with CyberKnife in Málaga?
The versatility of the CyberKnife system allows for the treatment of a wide range of conditions, both benign and malignant, which previously required complex open surgeries or were considered inoperable due to their deep location or proximity to critical structures.
· Primary brain tumours and metastases
One of the most frequent applications is the treatment of brain tumours, both primary (such as meningiomas or acoustic neuromas) and metastatic. In the case of brain metastases, CyberKnife allows multiple lesions to be treated in a single session or in a reduced number of fractions, offering excellent local control with optimal preservation of cognitive function. For acoustic neuromas, this technology is especially valuable, as it allows tumour growth to be halted while preserving, in many cases, hearing and facial nerve function.
Arteriovenous malformations (AVMs)
Arteriovenous malformations are abnormal connections between arteries and veins that carry a risk of brain haemorrhage. In cases where open surgery or endovascular embolisation present high risks, CyberKnife radiosurgery offers a safe alternative. The radiation causes progressive thickening of the walls of the abnormal vessels until their complete occlusion, a process that occurs gradually over one to three years.
Functional pathology: trigeminal neuralgia
Beyond tumours, CyberKnife has proven highly effective in treating functional disorders such as trigeminal neuralgia. This condition, characterised by lancinating and disabling facial pain, can be treated by directing a precise dose of radiation to the root of the trigeminal nerve, interrupting pain signals without the need for invasive procedures at the base of the skull.
The Arráez Institute's experience with radiosurgery
At the Arráez Institute, we understand that even the most advanced technology is merely a tool in the hands of a specialist. Our approach is based on meticulous, personalised planning for each patient, integrating radiosurgery within a multidisciplinary treatment plan.
A patient-centred process
The CyberKnife treatment begins with a planning phase where high-resolution MRI and CT scans are fused. Radiosurgery precisely outlines the tumour volume and critical structures to be protected with sub-millimetre accuracy. During the treatment session, the patient lies comfortably while the robotic arm moves silently around them, delivering radiation from hundreds of different angles.
Advantages of robotic radiosurgery (CyberKnife System)
The main advantage for the patient is the absence of pain and the speed of recovery. As it does not require incisions or the use of stereotactic frames screwed into the skull (common in other radiosurgery systems), the procedure is much more comfortable. Most patients can resume their usual activities immediately after the session, which is an invaluable benefit to their quality of life.
Furthermore, the CyberKnife's ability to fractionate treatment (administer it in 2 to 5 sessions) allows for the treatment of larger lesions or those located very close to the optic nerves or brainstem, minimising the risk of complications that could occur with a single massive dose.
Innovation in the service of health
CyberKnife radiosurgery has transformed the landscape of neuro-oncological and functional treatment. In the Arráez Institute, We continue to invest in technological innovation as a means to achieve excellence in our patient care. This technique not only offers an effective alternative to conventional surgery in many cases, but also opens new doors of hope for those patients with complex diagnoses.
