Gamma Knife Radiosurgery uses radiation to kill cancer cells and shrink tumors :Gamma Knife Surgery for Brain in India

What is Gamma Knife Surgery or Radiosurgery ?

Gamma Knife radiosurgery, also called stereotactic radiosurgery, is a very precise form of therapeutic radiology. Even though it is called surgery, a Gamma Knife procedure does not involve actual surgery, nor is the Gamma Knife really a knife at all. It uses beams of highly-focused gamma rays to treat small to medium size lesions, usually in the brain. Many beams of gamma radiation join to focus on the lesion under treatment, providing a very intense dose of radiation without a surgical incision or opening.

Gamma Knife radiosurgery is called “surgery” because a result similar to an actual surgical procedure is created by a one-session radiation therapy treatment. The beams of radiation are very precisely focused to reach the tumor, lesion, or other area being treated with minimal effect on surrounding healthy tissue.

Gamma Knife radiosurgery is most often used to treat tumors and other lesions in the brain. It is also used to treat certain neurological conditions, such as trigeminal neuralgia (a condition in which pressure on the trigeminal nerve causes spasms of extreme facial pain) and acoustic neuroma (a noncancerous tumor in the brain that affects the nerves that control hearing).

Gamma Knife radiosurgery may be used in situations where the brain lesion cannot be reached by conventional surgical techniques. It may also be used in persons whose condition is such that they might not be able to tolerate a surgical procedure, such as craniotomy, to treat their condition.

Because the therapeutic effects of a Gamma Knife procedure occur rather slowly over time, it is not used for persons whose condition requires more immediate therapy.

In what cases Gamma Knife Surgery is preferred in India?

Following are the conditions where Gamma Knife Surgery is successfuly used in India:

• Intracranial tumors such as acoustic neuromas, pituitary adenomas, pinealomas, craniopharyngiomas, meningiomas, chordomas, chondrosarcomas, metastases and glial tumors

•Vascular malformations including arteriovenous malformations

•Functional disorders such as Trigeminal neuralgia, Intractable pain , Parkinson’s disease, Essential tremors , Epilepsy and Obsessive-compulsive disorder

What are the advantages of Gamma Knife Surgery over traditional Open Surgeries?

•Non Invasive Procedure
•Very less or no complications
•Done on out patient basis so no admission required
•Cost of gamma kife surgery is lower than that of open surgery
•Minimal harm to the healthy tissue as compared to open surgery
•Very high success rate

Who can perform a Gamma Knife Surgery?

Gamma Knife Surgery is performed by a Neurosurgeon who is very well trained in performing the gamma knife surgery. In India there are some of the very good neurosurgeons for gamma knife surgery.

Back to your normal routine 

Once your treatment is complete, the head frame will be removed. If you had an angiogram, you might have to lie quietly for several more hours. Some patients experience a mild headache or minor swelling where the head frame was attached, but most report no problems. Your doctor will tell you whether or not he wants you to stay overnight for observation or if you can go home immediately. Either way, you should be able to return to work or your normal routine in another day or so.

The effects of your Leksell Gamma Knife treatment will occur over time. Radiation treatments are designed to stop the growth of tumors or lesions, which means they won’t disappear immediately but over a period of weeks or months. Your physician and Leksell Gamma Knife® team will stay in contact with you to assess your progress, which will include follow-up MRI or CT images in the near future and periodic check-ups.
