A Non-Invasive Alternative

The Leksell Gamma Knife® Perfexion™ is an effective, non-invasive alternative to traditional brain surgery. This highly sophisticated technology precisely directs focused radiation to specific targets in the brain. Typically performed in a single outpatient treatment session without general anesthesia, this proven technique helps patients avoid incision, scarring, and long hospital stays while minimizing surgical complications. For many conditions, Gamma Knife Perfexion treatment is the most accurate form of stereotactic radiosurgery available. See the FAQs for more detailed information about the Gamma Knife Perfexion.

Conditions treated with the Gamma Knife include:

• 1.
  Malignant Tumors - metastatic tumors (cancer spread to the brain), gliomas, chondrosarcoma
• 2.
  Benign Tumors - acoustic neuromas (vestibular schwannomas), meningiomas, pituitary adenomas
• 3.
  Vascular Abnormalities - arteriovenous malformations
• 4.
  Functional Disorders - trigeminal neuralgia (also known as tic douloureux or chronic facial pain)

Candidates for Gamma Knife Treatment

Neoplastic and vasculardisorders account for the majority of radiosurgical procedures today. The Gamma Knife is effective in controlling tumor growth and hemorrhaging from vascular malformations and targets lesions so exactly that the risk of harming healthy tissue is minimized. In certain cases, Gamma Knife treatment may serve as an adjunct to standard neurosurgical therapy or as the preferred course of treatment when further traditional therapy is not recommended.

Gamma Knife treatment is often the preferred alternative for patients who are not candidates for conventional neurosurgery or radiation therapy. It also may be recommended as an additional therapy for individuals who have already undergone surgery or radiation and require further treatment.

The Gamma Knife may also be recommended for patients with the following conditions:

• •
  Tumors or vascular malformations that are surgically inaccessible
• •
  Risk factors that make surgery inadvisable
• •
  Need for an additional dose of radiation following conventional radiation therapy
• •
  Recurrent tumors
• •
  Facial pain

Our multidisciplinary team (including neurosurgeons, radiation oncologists, radiation physicists, neuroradiologists, oncologists, neurologists, nurses and radiation therapists) evaluates each patient to determine whether Gamma Knife treatment is the best option. The patient's medical history is reviewed, along with imaging studies and information provided by the patient's physician. If Gamma Knife treatment is not considered appropriate, the team will suggest an alternate treatment option.
