Indications

There are numerous brain lesions for which treatment, either surgical or with radiation, is associated with considerable mortality or morbidity due to factors such as depth and inaccessibility of the lesion, its adjacency to arteries, nerves and other vital structures, and the radio sensitivity of adjacent normal tissues. Even if access is possible, surgery still involves risks of hemorrhage, infection and other post-operative complications. In addition, a lengthy hospital stay is usually required.

The Gamma Knife allows noninvasive (without opening of the skull) cerebral surgery to be performed with extreme precision while minimizing dose to the surrounding tissue. Based on preoperative radiological examinations, such as CT-scan, MR-scans, conventional X-rays and/or angiography, the unit provides for accurate irradiation of deep-seated targets, using a multitude of collimated beams of ionizing radiation.

With the Gamma Knife, a surgical incision is not required; the attendant risks of open neurosurgical procedures (mortality, hemorrhage, infection, etc.) are therefore minimal. In addition, the costs of the single procedure, professional fees and hospitalization are often 30 to 70 percent less than those of conventional Neurosurgery.

The Gamma Knife may be used as an alternative to standard neurosurgical operations or as an adjuvant therapy in the treatment of residual or recurrent lesions left unresected by conventional surgery.

Radiosurgery can be especially useful for those patients who are not suitable for standard surgical techniques due to illness or advanced age. In many neurosurgical cases, the Gamma Knife is only feasible treatment modality.
