Gamma Knife Neurosurgery in the Management of Intracranial

By using this method, doctors are able to focus on the radiation directly, targeting the brain without having to worry about affecting the surrounding healthy tissue. The Gamma Knife is an advanced radiation treatment for small to medium primary or metastatic brain tumors, abnormal blood vessel formations called arteriovenous malformations, epilepsy, trigeminal neuralgia, a nerve condition that causes chronic pain, and other neurological conditions. 2021-02-24 · Comparing stereotactic radiation with microsurgery, studies show substantially less cost for radiation treatment of acoustic tumors smaller than 3 cm in diameter and comparable results in terms of postoperative outcomes, as of mean follow-up periods on the order of 5-10 years for most gamma knife studies and 3-4 years for LINAC based fractionated treatment studies. One of the key components of the Gamma Knife — the tool that allows your doctor to precisely pinpoint your tumor or problem — is the special stereotactic head frame. This lightweight frame, which is attached to your head with four small screws, ensures that the radiation beams are precisely targeted.

Designed specifically for the brain, Gamma Knife radiosurgery replaces the surgeon’s scalpel with multiple narrow beams of radiation targeted to a specific area. Contrary to its name, there is no knife. No incisions are involved in this proven procedure. OBJECTIVE The authors present long-term follow-up data on patients treated with Gamma Knife radiosurgery (GKRS) for acoustic neuroma. METHODS Six hundred eighteen patients were radiosurgically treated for acoustic neuroma between 1992 and 2016 at the Department of Neurosurgery, Medical University Vi … Technologically advanced: The Gamma Knife® is robotically controlled, allowing surgeons to deliver radiation more precisely, safely and faster than ever before.

Gamma Knife uses high-intensity radiation therapy that concentrates radiation to a single targeted area. This approach is meant to kill cancer cells and shrink tumors without harming surrounding healthy tissue. The Gamma Knife approach entails delivering multiple, radiation beams simultaneously to the target area or tumor location. Gamma Knife® is a non-invasive stereotactic radiosurgery instrument that involves no scalpel or incision – it’s not a knife at all. Instead, the Gamma Knife® uses up to 192 precisely focused beams of radiation to control malignant and nonmalignant tumors, … Gamma Knife surgery is a painless computer-guided treatment that delivers highly focused radiation to tumors and lesions in the brain.

Dr. Duma uses the Gamma Knife Perfexion™ to perform surgical techniques on the brain for more accuracy and precision. With the Gamma Knife device, a finely focused, high dose of radiation is delivered from 192 individual radiation sources that are positioned to precisely converge on the tumor area. By having lower doses of radiation from multiple sources converge on a single location, normal tissue in the path of each individual source receives a minimal dose, reducing the chance of radiation injury.
