Radiosurgery is an alternative form of treatment for:
versus classical craniotomy or total brain irradiation.
It is a non-invasive method, usually performed as a one day treatment and is well tolerated.
With this method, a high dose of radiation is given, with very high precision, to small intracranial targets (tumors or focal lesions), usually in one session, leaving the rest of the brain intact.
No recovery time is required, which is very important for patients who can return to their daily activities the next day of treatment.
It is an ideal treatment for pediatric patients because the dose affecting healthy brain tissue is minimal.
The complications are minimal but relatively insignificant compared to those resulting from the surgical approach, depending of course on the location of the brain injury.
Radiation surgery is not aimed at removing brain damage, but destruction of the DNA of the cells of the tumor, which lose reproductive capacity, are destroyed and removed with the help of the body's defense system.
In arteriovenous malformations, Radiosurgery causes thickening of the walls of the vessels, which are eventually blocked.
In the trigeminal neuralgia, targeted and controlled damage of the trigeminal nerve is performed in the area where the trigeminal nerve stems from the brain stem.
The therapeutic effect for benign tumors and vascular malformations becomes evident in about 6 - 24 months, while for malignant and metastatic tumors even at 2-3 months.
Radiation surgery can be applied as a first therapeutic option on its own or in combination with other therapeutic techniques (surgery, radiotherapy, embolism). Also, a serious advantage is the ability to irradiate more than one targets in the same session, without any further complications from irradiation of part or the entire brain.
It requires close cooperation between Neurosurgeon and Oncologist Radiotherapist for the appropriateness of treatment on a case-by-case basis, the determination of target and radiosensitive areas, therapeutic doses and tolerance limits of the physiological structures, the purpose of therapy and possible combination with other therapeutic options.
