GREENVILLE, NC – Last month, Dr. Stuart Lee, neurosurgeon at Vidant Neurosurgery in Greenville, performed the 1,000th Gamma Knife case at Vidant Medical Center. The Gamma Knife machine, only one of two in the state of North Carolina, offers non-invasive treatment of brain disorders, such as metastatic brain tumors, meningiomas, trigeminal neuralgia and vascular malformations. 

“The Gamma Knife allows physicians to accurately perform stereotactic radiosurgery, which is a significant technological advancement in the treatment of brain tumors and other neurological disorders,” said Todd Hickey, senior vice president at Vidant Medical Center.

Before a patient undergoes Gamma Knife surgery, a team of radiation oncologists and neurosurgeons prepare a detailed treatment plan based on comprehensive images of the patient’s brain/face, which can include a magnetic resonance (MRI), computerized tomography (CT) and/or angiography (AI) scan. The imaging information is used to direct the radiosurgery treatment with sub-millimeter accuracy. This accuracy is due, in part to a collimator helmet that focuses radiation beams on a particular target. 

“There is no other technology as accurate as the Gamma Knife,” said Dr. Lee. “This technology gives us virtually unlimited reach to any place in the brain down to the mid-cervical spine and allows us to treat the targeted lesion with the greatest possibly accuracy while sparing nearby normal tissues.”

The new Leksell Perfexion™ system, installed in 2013, also delivers patient comfort and safety.

“The previous system often required the patient’s head to be flexed during treatment,” said Dr. Lee. “With Perfexion™, the patient’s head remains in a neutral position while delivering a high dose of radiation to the lesion with very little radiation to the surrounding normal brain tissue.”

The 2,800-square-foot facility on the Vidant Medical Center campus houses the Perfexion™ Gamma Knife technology and patient preparation rooms. The Gamma Knife was originally installed in October 2005. 
The Gamma Knife option for brain surgery offer many advantages over traditional, invasive methods. Specifically, the cost is less to the patient, recovery time is notably shorter and less painful, and the results are well-validated over several decades. Also, deep brain lesions that otherwise might not be operable, now can be treated with precision.
