Gamma Knife is an apparatus for high-precision simultaneous irradiation of various pathological formations of the brain. It uses the energy of gamma radiation from radioactive cobalt-60 and is perceived as representative of radiosurgical treatment.
However, unlike other radiation therapy facilities using cobalt-60, the Gamma Knife is based on the method of stereotactic guidance of radiation to an irradiated object.
Why the Gamma Knife is decent medical maintenance?
Pay heed to the information that you can find the best offers for Gamma Knife for AVM treatment on the https://bookinghealth.com/programs/treatment/Gamma-knife/arteriovenous-malformation-radiosurgery-gamma-knife. It’s no accident that well-known clinics from all over the world use this method as it has many positive moments.
- Non-invasive treatment. Despite its name, there are no cuts. Therefore, there are no complications associated with classic surgery.
- The effectiveness of the treatment. More than 85% of tumors treated with a gamma knife do not return. Gamma Knife therapy is a proven method.
- Accuracy. The specified way of treatment is known for its high degree of accuracy (it’s guaranteed to 0.5 mm). It can boast with the ability to accurately focus radiation on the individual cast of the tumor, narrowing down the radiation of contiguous sound tissues.
- One treatment session. As distinct from typical radiation therapy, when the patient has to pass nearly 30-40 sessions and get small doses, a Gamma Knife brings a heavy dose of radiation to brain oncomas in one manipulation. Powerful radiation damages the DNA of abnormal cells, stopping tumor growth.
- Quickly and carefully. Most patients are able and allowed leaving the clinics on the same day but you have to know that the continuance of the specified procedure reaches several hours. The time you spend in the hospital is minimized.
- Minimal side effects. Since the radiation focuses precisely in the tumor, the risk of a negative effect on the neurocognitive function of the cerebrum is diminished. Some people may experience headaches right after treatment.
- Flexibility. A Gamma Knife is a decent option to treat tumors that cannot be safely exsomatizes via surgery. For example, metastases in the brain stem.
- Repeated treatment. Patients undergo a repeated radiosurgery procedure when new tumors appear.
It should be especially emphasized that Gamma Knife therapy is indicated for patients with small abnormal focus (up to 3-3.5 cm), which don’t cause unpleasant neurological symptoms, with a mild benign tumor or brain cancer symptoms. Radiosurgery is also indicated in cases where the surgical intervention did not lead to the complete elimination of the disease, or when it recurs. The radiosurgical treatment is also preferable for elderly and debilitated patients, as they undergo this procedure much easier than classic surgery. Notwithstanding the above, the use of radiosurgery is contraindicated in the case of rapidly developing symptoms of the brain compression, for example, a large tumor.
