Stereotactic radiosurgery produces tissue destruction in its intracranial target, which is defined by targeted launching of a focus of ionizing radiation from a linear accelerator. The radiation is given while preserving the majority of the brain tissue surrounding the lesion. The radiosurgical treatment is a minimally invasive treatment and as such the associated mortality and morbidity are very small when compared to the existing microsurgical treatment.
The existing surgical treatment involves surgery under general anesthesia and requires opening the skull in order to reach the target and remove it. The conventional surgery involves a longer recovery time and the rate of complications and neurologic deficit are considerable. On the other hand, the radiosurgery procedure is performed in the Outpatients department. The patient receives radiation therapy once, is released to his home the same day, and can return to his ordinary pursuits the next day.
The immediate complications after radiosurgery are small and relatively negligible compared with conventional surgery. There are long-term complications after radiosurgery whose frequency decreases with the continuous improvement in imaging methods, programming of the operating of the system, and the hardware of the components of the system for radiosurgery. In addition, the cumulative worldwide experience in radiosurgical procedures has resulted in a more accurate determination of the doses of radiation that are now given with various indications, which has greatly reduced the rate of long-term complications.
The radiosurgery treatment using stereotactic techniques has proven to be effective and safe with the following indications:
- AVM - arterio-venous malformations in the brain
- Benign brain tumors
- Acoustic neurinoma, meningiomas in critical areas of the brain
- Malignant brain tumors - brain metastases, primary tumors
- Functional radiosurgery - treatment for trigeminal neuralgia
Stereotactic radiosurgery - Dose 1
The procedure begins by assembling a rigid stereotactic head frame to the head of the patient under local anesthetic. The frame allows a basis for fixing the coordinates of the selected therapeutic target in space and is used for location and fixation of the head of the patient during radiation treatment. With the frame attached to his head, the patient undergoes CT or angiography (depending on the type of lesion) and the imaging data are transferred to a computer for planning the treatment.
The existing programs allow us to set the target and implement the therapeutic planning within 3 to 6 minutes. After approval of the plan by a neurosurgeon, radiotherapist and physicist, the patient is transferred to the treatment room where the tratment is given in one fraction for 30-45 minutes.
During treatment the patient is monitored by CCTV and a microphone that allow continuous contact between the patient and the treating doctor. The rigid stereotactic frame is removed at the end of treatment and after supervision for about an hour, the patient is discharged home on the same day. The patient is allowed to return to his regular activities on the next day.
