Gamma knife surgery is a non-invasive method of treating malignant and benign brain tumors. It uses focused beams of radiation to precisely irradiate the target area, minimizing the impact on surrounding healthy tissues.
The gamma knife delivers about 200 beams of radiation to the exact target area. Each beam has a low intensity, but a high dose of radiation accumulates at the point of their intersection, which makes it possible to destroy the tumor.
Operation procedure using a Gamma knife:
- First, a stereotactic frame will be placed on the patient's head to ensure accurate positioning during the procedure.
- An MRI or CT scan is then performed to determine the exact location of the tumor.
- A treatment plan is created based on these images.
- During the procedure, the patient lies motionless, and the Gamma knife rotates around his head, delivering radiation to the tumor.
- The procedure usually takes from 30 minutes to several hours.
Advantages of the operation using a Gamma knife:
- Non-invasiveness
- High precision
- Minimal impact on the surrounding healthy tissues
- Low risk of side effects
Gamma knife surgery is suitable for the treatment of various brain tumors, including:
- Meningiomas
- Acoustic neurinomas
- Brain metastases
- Arteriovenous malformations
- Trigeminal neuralgia
Gamma knife surgery may be unsuitable for patients with:
- Large or complex tumors
- Tumors located near critical brain structures
- Severe concomitant diseases
Side effects of Gamma knife surgery are usually minimal and may include:
- Nausea and vomiting
- Fatigue
- Hair loss in the treatment area (rare)
Gamma knife surgery is an effective and minimally invasive method of treating brain tumors. It provides high precision and minimal side effects, making it an attractive option for patients looking for an alternative to traditional surgery.
