Is Gamma Knife® Right for Me?
Gamma Knife radiosurgery has changed the landscape of neurosurgery, recognized worldwide as one of the most advanced means available for the treatment of brain disease.
The preferred treatment for brain tumors, arteriovenous malformation and brain dysfunctions such as trigeminal neuralgia, it allows noninvasive cerebral surgery to be performed in a single session with extreme precision to the target, sparing surrounding healthy tissues.
Backed by more than two decades of clinical application in the U.S. and supported by thousands of peer-reviewed journal articles, Gamma Knife surgery has become the world’s most widely used radiosurgery treatment due to its extraordinary accuracy, reduction of excess radiation dose to the body, extensive history and clinical documentation.
The successes of the Lancaster General Health Gamma Knife radiosurgery team members are reported in the Seven Year study . Observing more than 1,000 patients at LGH, the team pronounced the treatment safe, “and in many conditions, highly efficacious.” In the time period evaluated, they reported less than 2 percent of patients suffered significant complications, no cases of radiation induced tumors and rare cases of hair loss.
Based on preoperative radiological examinations, such as CT scans, MR scans and angiography, the unit provides highly accurate irradiation of even the most deep-seated targets, using a multitude of collimated beams of ionizing radiation. These beams of low-intensity radiation converge to deliver a single, therapeutic dose of radiation with proven pin-point precision to the most difficult targets; while integrated treatment planning and delivery streamlines the radiosurgery process to treat even multiple brain lesions in a single automated procedure.
Currently, the Gamma Knife is used primarily to inactivate benign brain tumors (acoustic neuromas, meningiomas, pituitary adenomas, craniopharyngiomas and other tumors of the skull base and brain); malignant tumors; pain conditions such as trigeminal neuralgia; movement disorders such as tremor; and treatment-resistant epilepsy. Gamma Knife radiosurgery is a preferred option for many patients with cancer that has spread (metastasized) to the brain.For certain patients with deep-seated tumors or AVMs, the Gamma Knife may be preferable to conventional surgery. Because the unit can tailor radiosurgical doses to lesions of suitable size, it is used as an alternative microsurgical or endovascular embolization in these patients.
The Gamma Knife offers a non-invasive alternative for many patients for whom traditional brain surgery is not an option. Gamma Knife surgery removes the physical trauma and the majority of risks associated with conventional surgery. Only local anesthesia and mild sedation are needed and patients may resume their usual activities within 24 hours.This effective single session treatment may require an overnight hospital stay, but is most often done in an outpatient surgical setting with periodic follow-up. It has been proven safe over the long term and is recognized and covered by insurance plans.
