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 Arr\u00e1ez 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.<\/p>\n\n\n\n
Unlike conventional radiotherapy which delivers low doses of radiation in multiple sessions over weeks, lCyberKnife radiosurgery<\/mark><\/a> <\/strong>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.<\/p>\n\n\n\n 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.<\/p>\n\n\n\n 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.<\/p>\n\n\n\n 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.<\/p>\n\n\n\nWhat pathologies can be treated with CyberKnife in M\u00e1laga?<\/h1>\n\n\n\n
