Benefits to Patients
No surgical complications: The risks of surgery, such as infection, hemorrhage, or leakage of cerebral spinal fluid, are nonexistent.
No general anesthesia: The procedure is performed primarily with local anesthesia and mild sedation, eliminating the side effects and risks of general anesthesia and intubation.
Highly targeted treatment: Gamma Knife radiosurgery affects only the diseased areas of the brain, sparing unnecessary radiation of nearby, normal brain tissue.
Expedited treatment: Gamma Knife radiosurgery is a one-day treatment compared to other treatments that must be repeated several times, though can be repeated if necessary.
Gamma Knife radiosurgery can provide definitive care in a timely manner to avoid delays in systemic treatment for cancer patients. Traditional surgical approaches can often delay radiation treatment and chemotherapy initiation.
Cost-effective: Gamma Knife radiosurgery reduces costs associated with traditional brain surgery and post-operative hospitalization. Patients are usually able to leave the hospital within a day and resume normal activities immediately. Post-surgical disability and convalescent cost are nonexistent.
Patient-friendly: Because Gamma Knife is minimally invasive, patients experience virtually no discomfort. Patients are treated on an outpatient basis.
Excellent success rate: After two decades of research, no other neurosurgical tool has shown such consistently positive results as the Gamma Knife. After treatment, most brain tumors disappear or stop growing over time. After one year, 40 percent of arteriovenous malformations (AVMs) are cured, increasing to 80 percent two years after treatment. More than 1.1 million patients have had Gamma Knife radiosurgery since its introduction in 1968.
