Gamma Knife Radiosurgery

The addition of Leksell Gamma Knife® technology at Vidant Medical Center in 2005 offered new hope for patients with brain lesions that were once considered inoperable. The use of Gamma Knife alleviates much of the pain, scarring and long recovery time associated with conventional open-brain surgery.

Now, we are pleased to deliver the newest tool for non-invasive neurosurgery, the Leksell Gamma Knife® Perfexion. The Perfexion machine is the most advanced radiosurgery technology available. It can be used on an expanded treatment area - including the upper spine - which allows us to treat a greater number of patients and conditions. Only two hospitals in North Carolina provide Perfexion surgery, and we are proud to offer this unique service so close to home.




Precise treatment, expert care

Gamma Knife allows surgeons to effectively treat brain lesions without picking up a scalpel. The technique offers unmatched accuracy and precision, and delivers sophisticated treatment plans in significantly less time. Perfexion makes the procedure even safer by using up to 100 times less radiation than other technologies. Most patients experience little pain, go home the day of the procedure, and resume their normal activities within 24 hours. Two patients, Lee Peter and Connie Nanney, recently shared their experiences with Gamma Knife. Lee, Vidant Medical Center's 1000th Gamma Knife case, shared her story about her struggle with trigeminal neuralgia. Connie shared how Gamma Knife is helping her in her second battle with cancer.

Indications for Gamma Knife therapy

Gamma Knife therapy may be considered for patients with the following diagnoses:

  • Brain metasteses
  • Meningiomas, acoustic neuromas, pituitary adenomas, craniopharyngiomas and other benign tumors
  • Trigeminal neuralgia
  • Primary or recurrent malignant brain tumors including astrocytomas and oligodendrogliomas
  • Vascular malformations of the brain such as AVM and cavernous malformation
  • Intracranial tumors such as nasopharyngeal carcinomas and ocular melanomas

Gamma Knife radiosurgery is an alternative to conventional neurosurgery. The non-invasive procedure is especially useful for patients who are not good candidates for standard surgery because of illness or advanced age. In many cases, the location or nature of the lesion makes Gamma Knife the only feasible treatment. The technique can also be used as an additional therapy when surgery and other treatments are not completely successful.
